Maize grain production may be increased by growing varieties that utilize the available nutrients in the soil efficiently. High grain yield of maize could be achieved when hybrid variety was planted under the optimal rate of fertilization. However, application of fertilizer on agricultural land in large quantities have a negative impact on the environment. Therefore, maize variety that is able to use fertilizer efficiently is needed, which would be reducing the environmental impact from a high fertilization and also helping farmers who are less able to provide optimal fertilizer rate or those who are growing maize under the marginal land. Maize genotypes developed by diallel mating and their parents were tested under nested design, three replications on two levels of nitrogen fertilization (low and optimal N level, as nested factor). The full diallel crosses (hybrids and reciprocals) derived from five inbred lines were tested using Griffing method I. Result indicated that H3, H7 and H9 hybrids were adaptable to low N. Inbred G2 and G5 were suitable for optimal N fertilization condition, and their single cross hybrids using H7 as parent was suitable for the low N fertilization condition. Inbred G4 was suitable for low N condition and inbred G5 was suitable for the optimal N condition. Single cross hybrids of H10 was as parent suitable for N optimal condition. It was shown that maize hybrids suitable for low or optimal N fertilizations could be generated from either pairs of inbreds adaptif under low N or optimal N conditions. Inbred lines adapted to certain N fertilization may not necessarily produced hybrid adapted to the same N level of environment.

Improving Ciherang rice variety for earliness and higher productivity was obtained using Marker Assisted Backcrossing (MAB). Among 78 lines of BC2F4 generation of Ciherang x Nipponbare were obtained from greenhouse and molekuler analysis selection. Field evaluations were conducted at two locations, namely field station of Sukamandi (Indonesian Center for Rice Research, West Java), and field station of Maros (Indonesian Cereals Research Institute, South Sulawesi). Molecular analysis was performed using markers RM1362 and RM7601 which are flanking markers for the QTL region for Hd2 gene, located on chromosome 7. Flowering time and grain yield were evaluated among BC2 F4 lines. Five lines flowered earlier and yielded higher than Ciherang were selected for background analysis using microsatellites covering the rice chromosomes. The earliest flowering line was BC2F4 CihNip-60 (at 74 days, 4 days earlier than that of Ciherang), and the highest yield (which flowered earlier than Ciherang) was BC2 F4 CihNip-23, namely (2.20 t/ha higher than Ciherang). A total of 74 (95%) BC2 F4 lines showed QTL region of Hd2 gene in homozygous condition. This showed that molecular selection from F1 generation of BC2 F4 was able to identify homozygous gens and almost free of contaminant plant. Genetic backgrounds of the five BC2 F2 selected lines were similar to that of Ciherang. Based on the agronomic and molecular marker, twenty five lines of BC2 F4 flowered earlier than did Ciherang and yielded higher than did Ciherang. These lines should be further evaluated for their stability

Bacterial leaf blight control in rice (Oryza sativa Lin.) using bactericide is prohibitive, due to its high cost and its negative effect on the environment. Biocontrol when avaible, therefore is the best alternative solution. Bacillus subtilis is a perspective of biocontrol agent to control several plant diseases, because of its ability to produce antimicrobial and produce plant growth promoting substances. This research was aimed to examine the effectiveness of B. subtilis spore formulation by way of seed treatments and foliar sprays, using different frequencies and concentrations, to control bacterial leaf blight disease (BLB) on rice, caused by Xanthomonas oryzae pv. oryzae, and to evaluate its function as plant growth promoter. The experiments were conducted at greenhouse and in the field using factorial design. At the greenhouse experiment, seed treatment and foliar spray, using concentration of 2% produced better result in controlling BLB, and better result on promoting rice plant growth. In the field experiment, application at 2 week interval showed better effect on suppressing the the disease and on increasing yield. Applications of the formulation of B. subtilis B12 spore reduced BLB disease by 21% and potentially increased yield up to 50%.

The local Madura maize variety planted on drought stress area suffered retarded plant growth and reduced grain yield. Research was conducted to alleviate the stress on crop plants, to survive under drought condition. The aim of this study was to investigate the effects of MVA and ALA on the growth of Guluk-guluk local maize variety planted under difference drought stresess. The experiment was conducted using split-split plot design with three factors in six replications. The first factor was variation of MVA application, i.e., without inoculation (M0) and with inoculation of mycorrhiza (M1). The second factor was ALA treatment which consisted of 3 levels, namely 0% (P0), 0.05% (P1) and 0.1% (P2). Third factor was plant watering intensity, i.e., watered once every 2 days (K0), watered once every 4 days (K1) and watered once every 6 days (K2) reaching field capacity, respectively. Data were analyzed by two-way ANOVA and Duncanâs Multiple Range Test (DMRT). The results suggested that MVA and ALA treatments gave significant effects in increasing the percentage of mycorrhiza infection, total leaf P content, total chlorophyll content, plant height, fresh and dry weight of shoot and root and shoot/root ratio. It showed a significant effect in decreasing ABA content in maize plant subjected to drought stress. The ABA content was 1.7 ppm in plants watered once every 2 days, where control plant had ABA content of 5.8 ppm. The best treatment was found on plants treated with mycorrhiza inoculation and 0.05% ALA and watered once every 4 days.

Blast is one of major disease on the upland rice in Indonesia. Upland rice lines derived from Kasalath and NILC443 crosses, containing Pup1 gen locus had been developed and evaluated for P fertilizer efficiency. Those lines would be evaluated for blast resistance, due to the fact that Pup1 locus contains genes involved in plant defend mechanism to disease, including blast disease. The BC2F5 plants derived from six crosses (DK, DN, SK, SN, BK, BN) were used in this research. Responses to blast disease in the green house were evaluated at ICABIOGRAD Bogor from March to April 2011, using combination of three blast races (race 173, 033, and 133). The response to blast disease in the field was evaluated at Taman Bogo Research Station, Lampung, and at farmerâs field in Cikeusal Village, Banten, from January to April 2011. Molecular analysis to trace Pup1 gene locus was conducted at the Molecular Biology Laboratory, using specific primer K20-2, from January to August 2013. Based on the molecular analysis all Pup1 lines showed homozygoes alleles, except the heterozygoes alleles on SK7, SK8, SK15, SK16, BN8 line, which were then not included in the next planting. The responses to blast at greenhouse among lines varied, but the Pup1 lines were mostly at level of moderate resistan (AT). Based on the result from the field experiment, most of Pup1 lines were resistance, however the susceptible check plant (Kencana Bali) did not show blast fungus infection. Differences of the result might be due to the blast testing at the green house which was more favorable for blast fungal growth. The effect of Pup1 gene locus showed clearly on resistance of plants obtained from Situ Bagendit cross, where Situ Bagendit was susceptible and does not contain the Pup1 locus. Additional of Pup1 locus in Situ Bagendit genome had increased the degree of resistant to blast.

Breeding for high yielding rice varieties with VVEM (<90 days after sowing/ das) is considered important to increase cropping indexes in the fully irrigated farm lands. This research was aimed to evaluate the yield potential of 200 promising VVE and VE maturing rice lines. A total of 200 VVE and VE maturing rice lines and five check varieties (Ciherang, Dodokan, Inpari 1, Inpari 13, Silugonggo) were evaluated in Preliminary Yield Trial (PYT) at Sukamandi Experimental Farm using augmented design, during the dry season of 2012. The 17 lines selected from PYT along with three check varieties (Silugonggo, Inpari 13, Ciherang) were further evaluated in Advanced Yield Trial (AYT) using randomized complete block design at Sukamandi, Kuningan, Magelang and Klaten, during wet season of 2012. Of the 200 lines tested in PYT, three lines yielded significantly higher than the best check variety (Inpari 1) and 2 lines did equal to Inpari 1. A total of 155 lines were VVE (<90 das), and 45 lines were VE maturing (91-104 das). Based on yield per day, 17 lines were selected to be evaluated in AYT in WS 2012. Based on combined analyses from four locations of AYT, seven lines produced grain yield/ha and grain yield/day higher than did the best check Silugonggo (5.51 t/ha and 51.7 kg/day); there were14 lines did better than Ciherang (5.07 t/ha; 41.9 kg/day), and 13 lines yielded better than did Inpari 13 (5.27 t/ha; 46.7 kg/day). The best seven lines and lines with higher productivity per day than that of the best check, with an average yield of 5.62 t/ha up to 6.12 t/ha, with days to maturity from 87 up to 94 das, were ready to be evaluated in Multi Locational Yield Trial to meet the requirement for the release of new variety.

Breeding for sweet potato varieties rich in anthocyanins is essential to promote the use of sweet potato as functional food as well as to support food diversification program. This study was performed to identify physical, chemical, and sensorial characteristics of 10 promising clones of purple-fleshed sweet potato and two varieties (Ayamurasaki and Antin 1) as checks, at the Food Chemistry and Processing Laboratory of ILETRI, Malang from November until December 2012. The trial was arranged in a completely randomized design with three replicates. Observations included physical and chemical characteristics of the fresh roots and sensory attributes of the steamed roots using hedonic test of 20 panelists. The flesh colour varied from white/yellow purplish, purple up to dark purple. The lightness colour (L*) of root flesh was negatively correlated with total anthocyanins (R2 = 0.81), which varied from 1.86 mg (MSU 06044-05) up to 123.92 mg equivalent to cyanidin 3-glycoside/100 g fw (MSU 06046-48). Three clones, namely MSU 06046-48, MSU 06028-71, and MIS 0601-179 had higher total anthocyanins than that of Ayamurasaki (70.41mg/100 g fw) as a check. Moisture, ash, crude fiber, reducing sugar, amylose, and starch contents also varied among clones, ranged from 67.7 to 75.8%; 2.8 to 3.9% dw; 2.5 to 4.8%; 0.9 to 4.4% dw; 20.0 to 27.4% dw and 50.3 to 66.6% dw, respectively. MIS 0601-179 clone had the highest dry matter and starch contents (40.05% dw and 66.64% dw) which were suitable for flour ingredient. The steamed roots of MSU 06044-05 (yellow purplish) gave the highest scores of panelist preferences on colour, texture and taste attributes, followed by MIS 0601-179, Ayamurasaki, and MSU 06028-71 (purple). The bitter taste of MSU 06046-48 steamed roots associated with the highest anthocyanins content was slightly disliked, suggesting that this clone needs an alternative preparation method other than steaming.

Genetic parameters of a character, which is estimated using genetic analysis approach, is important in a character improvement. The aim of this research was to examine the gene action of days to maturity character on soybean using generation mean analysis. The research consisted two steps, first was preparing four populations (F1, BC1.1, BC1.2 and F2) of three single crosses, i.e. Nanti Ã— Grobogan, Grobogan Ã— Malabar, and Nanti Ã— Malabar. The second step was testing those populations consisting of P1, P2, F1, F2, BC1.1 and BC1.2 in the field at Jambegede Experimental Station, Malang, East Java, from July to September 2009. The results showed that there were interaction between the gene loci on the inheritance of days to maturity, from the three cross combinations under study. The role of additive gene action and the influence of dominant inheritance contributed jointly, affecting days to maturity of early maturity (Grobogan) and early maturity (Malabar) cross. The crossing of very late maturity (Nanti) with early maturity (Grobogan or Malabar) showed that early maturity was probably controlled by additive recessive genes.

Information on genetic diversity, homozygosity, drought stress and low N tolerance of maize inbred line are useful for parental selection in developing maize varieties tolerant to drought and low N. The objectives of this study were (a) selection for homozygoes lines and analysis of genetic diversity among 51 maize inbred lines applying simple sequence repeats (SSRs) using thirty six markers (b) selection for inbred lines (homozygosity over 80%) for drought and low nitrogen (N) tolerance. Experiment was conducted using split-split plots design with three replications. Water treatments were as the main plots (well-watered and drought stress conditions), subplots were nitrogen fertilization at rate of 75 and 150 kg N/ha and the sub-sub plots were 51 inbred lines. The results showed that there were broad ranges of genetic variability among inbred lines with genetic similarity coefficient values ranging from 0.22 to 0.87 and polymorphism information content average was 0.57. Thirty inbreds having homozygosity over 80% were spread into six heterotic groups. Drought tolerance inbreds were in heterotic groups C and F, namely DTPYC9-F46-3-9-1-1-B and 1044-30, the drought medium tolerance in heterotic group A and B, namely CML 161/NEI 9008 and MR 14. Inbred for low-N fertility tolerance was in the heterotic group D namely G20133077, while medium tolerance to low-N fertility inbreds were in heterotic group A, B, C, D, and F, and they were CML 161/NEI 9008, CY 11, CY 15, CY 6, CLRCY039, Nei9008, DTPYC9-F46-1-2-1-2-B, G2013627, G2013649, 1044-30. Inbreds tolerance to both medium drought and to low-N fertility were in heterotic group C and F they were DTPYC9-F46-1-2-1-2-B and 1044-30. Inbred lines of maize tolerant to drought and to low-N fertility can be used as parent to develop hybrid or synthetic varieties, posessing stress tolerances, by cross recombination between heterotic groups.
