Research on brown planthopper (BPH), (Nilaparvata lugens (Stal.) resistant to insecticide using dipping method was carried out in the wet season (WS) of 2011/2012 at Indonesian Center for Rice Research, Sukamandi. BPH field population from Sukamandi, West Java, known as Sukamandi BPH population and Juwiring, Central Java, as Juwiring BPH population, were measured their degree of resistance to insecticides to be compared with the BPH biotype 1 of screen house population. The insecticides used were imidacloprid, ethiprole, thiamethoxam, fipronil, BPMC, MIPC, buprofezin, cypermethrin and cyhalothrin. The resistance ratios (RR) were measured by LC50 of BPH from fields/LC50 of BPH from screen house. Results showed that Sukamandi BPH population was moderately resistance to imidacloprid and cypermethrin, but was low resistance to buprofezin, and was decreasing into susceptibility to fipronil, thiamethoxam and cyhalothrin, where as to ethiprole, BPMC dan MIPC the Sukamandi BPH was still susceptible. The Juwiring BPH population was low resistance to imidacloprid, buprofezin, cypermethrin and cyhalothrin, but the Juwiring BPH was decreasing into susceptibility to BPMC, ethiprole and fipronil. The population was still susceptible to thiamethoxam and MIPC.

Maize has an important role in the national economy, but at some area, including in Maluku, the productivity is still low, below its potential productivity. The productivity of maize could be improved by planting high yielding and adaptive variety to the local environment. Study was conducted in the Haruru village, District Amahai, Central Maluku, from March to August 2012 aimed to identify maize varieties adaptive on dry land agro ecosystem. The study used randomized block design, replicated three times, where farmersâ€™ fields were used as replications. The varieties tested were Srikandi Kuning, Gumarang, and Sukmaraga composites varieties. Bima-2 and Bima-2 (hybrid varieties) and Mutiara, Ungu Hati Putih, Merah, Orange Hati Putih, and Orange Hati Merah (local variety, obtained from farmersâ€™ fields in the district of MTB). Fertilizers were drilled, 5-7 cm on the side of plant at a rate of 135 kg N, 90 kg P2O5, 60 kg K2O and 1-2 t manure/ha. Variables to be measured were percentage of surviving plants, age at 50% of male flowering, age at 50% of female flowering, plant height, ear height, cob length, cob weight, cob diameter, number of rows/ear, seed number per ear row, 100-seed weight, weight of dry grains, moisture content, and grain yield. Results showed that local varieties indicated a better growth, but grain yield were superior for the hybrid and the composite varieties. Bima-4 hybrid variety produced 10.31 t/ha dry grain, followed by Bima-2 hybrid and the composite varieties of Sukmaraga, Srikandi Kuning, and Gumarang, each was 8.70 t/ha, 7.97 t/ha, 7.60 t/ha and 7.26 t/ha, respectively. Local varieties Mutiara, Orange Hati Putih, Merah, Orange Hati Merah, and Ungu Hati Putih each yielded only 3.74 t/ha, 3.32 t/ha, 3.07 t/ha, 3.02 t/ha and 2.45 t/ha respectively.

Brown planthopper is the most important rice pest in Indonesia. Its high adaptability to feed and reproduce on previously introduced resistant varieties to form more virulent population often causes BPH outbreak and hopperburn that lead to total crop yield loss. Rice breeding for resistant to BPH requires information on the current status of BPH virulences in the fields to anticipate the virulence adaptation on new varieties. The objectives of this study were to investigate the degree of virulence of BPH populations and to cluster the BPH virulence to form BPH core collection. Thirteen BPH populations collected from paddy fields in six provinces (Banten, West Java, Central Java, East Java, South Kalimantan, and South Sulawesi) in 2011 and 2013 were tested on 10 differential rice varieties and seven host varieties of BPH populations, using the standard seedbox screening technique. Based on resistance reaction of four differential varieties (TN1, Mudgo, ASD7, and Rathu Heenathi), most BPH populations were identified as more virulent than biotype 4 (T1, Banten, PG, West Java; BY, East Java; B2 and B3, South Kalimantan; X1 and X3, South Sulawesi), four populations were biotype 4 (JWDL, Central Java; SD, East Java; X2 and X4, South Sulawesi), and one population each was biotype 3 (T2, Banten) and biotype 2 (S1, West Java). Populations X1 and B3 showed broad virulences to all varieties, whereas T2 was the least virulent. BPH fieldâs population had evolved into more virulence than biotype 4. Genotype resistance screening should use the BPH of this virulence population. Five BPH clusters which were further divided into 10 subclusters representing differential virulence toward 10 differential varieties were present in the tested BPH. Each virulence cluster was characterized by its ability to overcome four to eight single or double resistant genes. This BPH virulence core collection can be used in the characterization studies of candidate for resistant varieties or to form near-isogenic lines, or to study the insect and rice plant interaction.

Al-stress on soybean causes inhibited root growth. Root length sensitivity index might be an indicator of roots tolerance to Alstress. Hematoxylin staining can be used to visualize the movement of Al in plant root tissues. This study was aimed to determine the tolerance level of soybean genotypes to the gradual Al concentrations. The experiment was conducted from February to April 2014, at the greenhouse in Cikabayan Experiments Garden, IPB, using a 4 x 3 factorial treatments in a completely randomized design, three replications. The first factor was the concentration of Al ie: without Al (A0); 0.5 mM Al (A1); 0.7 mM Al (A2) and 0.9 mM (A3). The second factor was the soybean varieties including: Tanggamus, Cikuray, and Ceneng. The observation of variable included root length sensitivity index based on hematoxylin staining, demonstrating the movement of Al on the tolerance and sensitive varieties. Results showed that: 1) Tanggamus was tolerance at 0.5 mM Al concentration and was moderate at 0.7 and 0.9 mM Al, 2) Cikuray was tolerance to a concentration up to 0.5 mM and was moderate at 0.7 mM Al but was sensitive to the concentration of 0.9 mM Al, 3) Ceneng was sensitive at concentration of 0.5 to 0.9 mM Al, 4) Staining hematoxylin indicated the root tissue advanced damages and darker blue color on the susceptible varieties, in comparison with the tolerant ones.

Black rice is a local rice variety with some advantages and weaknesses. The desirable character of black rice is its high anthocyanin content, while the weaknesses are late maturing, tall plant stature and low grain yield. Crosses were made between two parents aimed to recombine the superior traits. The effectiveness and efficiency of selection would be determined by the magnitude of the heritability of traits and the selection progress. This study was aimed to determine the heritability estimates in a broad sense and the genetic advance of agronomic characters of F2 generation, from crosses of local black rice and high yielding variety of white rice. The experiment was conducted in Padasan, Pakembinangun, Pakem, Sleman, Yogyakarta from January to May 2013. The F2 population derived from crosses of black rice x white rice, with the morphological traits of hairless black rice (S) crossed with Situbagendit (G) white rice, Cempo ireng (C) with Situbagendit (G) and Cempo ireng (C) with Inpari 6 (I). The F2 plants population were planted without replication. Genetic parameters estimated were calculated for broad sense heritability and genetic advance from selection. Results showed that the F2 population had high broad sense heritability estimates for all characters observed, including: plant height, flag leaf length, number of productive tillers, panicle length, number of filled grains per panicle, number of empty grains per panicle, maturity and rice color, in the three F2 populations obtained from crosses of S x G, C x G and C x I. Only the plant height of S x G cross had a medium broad sense heritability estimate. The large heritability estimates indicated that the respective character was controlled by genetic factor more than environmental ones. High genetic advance would be obtained in the flag leaf length, number of productive tillers, panicle length, number of filled grains/panicle, number of empty grains/panicle and rice color from S x G, C x G and C x I crosses. Genetic advance of plant height was medium (at S x G and C x I crosses) to high (C x G crosses). The maturity trait had low genetic advance on cross S x G; C x G; and Cx I. The high value of genetic advance of character would suggest that selection on the characterâ€™s appearance would be successful.

Some acid soil is potential for the agricultural development. Constraints for soybean production in the acid soils are Aluminum toxicity and macro nutrient deficiencies. Breeding for soybean varieties tolerant to acid soil is needed. This could be made through genetic engineering, by inserting acid tolerance genes into a soybean genome. Thirty one soybean lines (T0) had been obtained by insertion of Al tolerance genes (MaMt2) through an Agrobacterium mediated transformation, which nine of them contained MaMt2 gene based on PCR test. Further evaluation of those lines was carried out in the Biosafety Containment, where four T1 soybean lines were carrying MaMt2 gene, namely line GM2, GM5, GM10 and GM14. The study was aimed to evaluate the degree of tolerance of T2 generation of GM2, GM5, GM10 and GM14 lines to Al toxicity. Results showed that T2 line were able to grow in hygromicin media, indicating that those T2 lines were containing hygromicin resistant gene (hptII). Phenotypic analysis of T2 lines in four acid soil media treatments indicated that all lines could survive and grow on acid soil without liming and adding compost. GM2 line grew best on the acid medium than did other lines.

Grain yield of rice is determined by genotype (G), environment (E), and interaction between genotype x environment (G x E). Variety can achieve its maximum yield potential if it is grown in suitable environments. This study was aimed to determine the adaptability and the yield stability of rice genotypes grown in different environments. Sixteen rice genotypes were tested using RBD in 16 sites during the wet season of 2010/2011, and dry season of 2011. The tested rice lines were developed for resistance to pest and diseases. The experiment unit was 4 m x 5 m of plot, plants were fertilized with urea, SP36, and KCl at rates of 250 kg/ha, 100 kg/ha, and 100 kg/ha, respectively. Variable observed was grain yield per plot. Combined analyses of variance showed that there was no lines yielded higher than did check variety Conde. The AMMI analysis showed that the largest variation was contributed by the environment factors (76.49%), genotype x environment interactions (17.55%), and the smallest was contributed by the genotypes (5.97%). Data exploration using boxplot method indicated that the low contribution of the genotype x environment interaction variance in this study was due to the high degree of similarity of yield potentials among the genotypes, and due to high similarity of environmental conditions of the sites.Based on the analysis of AMMI 2, lines B12743 - MR-18-2-3-8, IPB107-F-82-2-1, and Conde was each classified as widely adapted genotypes, while G8, IPB107-F-27-6-1, and BIO111-2-BC-PIR-3714, each was considered as genotype having a specific adaptation.

Information on genetic diversity of QPM and Provit-A maize germplasm is important to support breeding program, in order to form a high yielding maize hybrid. Simple sequence repeats (SSR) have been extensively utilized as genetic markers to study the genetic diversity, cultivar identification, and gene mapping. The objectives of this research were to investigate the genetic diversity and to obtain information the genetic relationship among 20 maize accessions using 29 SSRs. The research was carried out at the Moleculer Biology Laboratory of Indonesian Cereals Research Institute (ICERI) in Maros, South Sulawesi. Twenty nine polymorphic primers that covered the 10 maize chromosomes were used to fingerprint the genotype of the lines, detecting 83 allels, with an average allel number of 3 allels per locus, ranging from 2 to 6 alleles per locus. The results indicated that polymorphism information content (PIC) ranged from 0.10 (nc133 and phi072) to 0.74 (phi064) with the average of 0.45. Genetic distance based on genetic similarity estimate ranged from 0.39 to 0.92. The high level of PIC values and wide genetic distances indicated the large variability among maize germplasm. Cluster analysis divided the 20 maize accessions into three groups. Coefficient cofenetic value (r) was 0.85 indicated a good fit based on the genetic similarity value. As many as 30 inbred heterotic recombinants were derived by incorporating 20 QPM and Provit-A with genetic distance of â‰¤0.65. The SSRs proved to be reliable and is practical technique for revealing the relationship among specialty maize genotypes.

Maize yield represents the interaction between genotype and environment. An excellent genotype should have high mean yield and small variation across common locations.This information could be obtained through yield performance test and stability analysis of yield data obtained from multilocation trials. This research was aimed to find out yield stability of eight early maturing maize promising lines at five sites using the AMMI method. There were total 12 genotypes of maize hybrids used in this research, consisted of eight hybrids (CH-1, CH-2, CH-3, CH-4, CH-5, CH-6, CH-7, and CH-8) and four check varieties (Gumarang, Bima 3, AS-1, and Bisi 2). This research was conducted at five locations ie. Gowa (South Sulawesi), Donggala (Central Sulawesi), Manado (North Sulawesi), Probolinggo (East Java) and Lombok Barat (West Nusa Tenggara) from April to September 2013. The treatments were arranged in a randomized complete block design (RCBD) with 3 replications. Variable measured was grain yield at all trial locations. Analysis of variance was performed for each site data to determine the performance of each genotype at each location. Results showed that genotype CH-2, CH-4 and CH-6 were considered as stable genotypes. Genotype CH-2 and CH-4 have a potensial to be released as new early maturing variety, due to its high yield of 8.71 and 7.52 t/ha averaged over 5 locations. Genotype CH-6 yielded below the mean yield of all genotypes, while genotype CH-8 was adaptive to a specific location, such as in Donggala, with yield of 8.38 t/ha.
