ABSTRACT Developing new rice varieties adaptive to heat stress is important to maintain high rice production in anticipating global warming effects. This research was aimed to find selection characters and to select the best segregant in early generation based on agronomic characters for adaptation of rice to heat stress. The experiment was carried out in September 2014 to Januari 2015. About 210 F2 segregants generated trough hybridization between IPB 4S (sensitive parent) and Situ Patenggang (tolerant parent), 20 individuals of IPB 4S, and 20 individuals of Situ Patenggang, were used as genetic control. All genetic materials were exposed to high temperature stress by growing in a green house of Bogor Agricultural University. The average temperature in the research period was 24 °C and 42.09 °C, respectively for minimum and maximum temperature. The results showed that charachters of productive and total tiller number, total grain number, and seed weight had high heritability, high coeffiecient of genetics variability-with an additive gene action. That charachters could be proposed as selection criteria in early generation for rice breeding of adaptation to high temperature stress. The characters could be applied in either single trait or multiple traits selection. Based on multiple traits selection we found 50 the best F2 segregation.Keywords: differential selection, early generation, heat tolerant, heritability, gene action, variability genetics coeffiecient

The objective of the research was to identify RAPD markers linked to QTL related to agronomic traits of soybean under low-light intensity condition. The genetic material used in the QTL analysis based on RAPD Markers were Ceneng, Godek, and F6 RILs derived from hybridization between Ceneng (tolerant parent) and Godek (sensitve parent). The results of molecular analysis showed that 9 primers were polymorphic and linked to the tolerant parent. Primers produce 14 RAPD markers which were polymorphic and linked to the tolerant parent. The markers were distributed into a linkage group that containing seven markers. RAPD Markers (OPE15-800, OPM20-800) were linked to two QTL controlling number of productive node and seed weight, respectively. The marker linked to the tolerant parent could be used as a marker assisted selection for high-yielding soybean lines under low-light intensity

The objective of this research was to determine the trait variance in black soybean lines in terms of yield and yield components. The materials used were F8 lines generated from hybridization of two local varieties, i.e. black seeded Ceneng and greenish yellow seeded Godek, and then selected under single seed descent method, except SC-39-1, SC-62-2 and GC-74-7 that were generated through bulk selection method. The results showed that the traits between plant genotypes were significantly different, except number of productive node and number of unfilled pod. Total variance was contributed more by number of filled pod, seed weight per plant and 100 seed weight. Seed weight per plant and 100 seed weight had high heritability with genetic variance and broad-sense heritability which were significantly different from zero. These characters are important for further selection to improve yields of black soybean lines.Keywords: black soybean lines, broad sense heritability, total variance

ABSTRACTDrought has become a main barrier of rainfed rice in dry climate and short wet season areas. Growing drought-tolerance varieties is a practical approach to minimize yield lost of rice by the drought stress condition. The aims of this research were to examine the inheritance of drought tolerance character, to identify selection traits, and to estimate genetic gain for drought tolerant on lowland rice. Four rice varieties, i.e., Jatiluhur, Mentik Wangi, IR64, Way Apo Buru, were fully diallel crossed. The parent varieties and the F1’s were grown at Sawah Baru, Dramaga experimental field in two irrigation treatments, optimum and sub optimum where irrigation was applied until three weeks after transplanting. A randomized complete block design with three replications for each irrigation treatment was applied to the experiment. The results showed that there is a significant maternal effect on tiller number. The values of additive variance were higher than the dominance for all other characters except tiller number and grain weight per plant. The highest value for narrow sense heritability was achieved by panicle length.Keywords: diallel, drought, genetic, rice

Iron (Fe) toxicity is a major constraint in rice production that decreases yield due to high level of soluble Fe. The aims of this experiement were to study the effect of particular Fe concentrations in nutrient solution on rice growth, and to determine Fe concentration in nutrient solution that caused light, moderate, and severe Fe toxiciy symptom. The experiment was conducted in a greenhouse, Bogor Agricultural University from May to July 2010. A randomized block design with two factors and three replications were used in this study. The first factor was Fe concentration in the medium solution (2, 50, 100, 200, 400, 600 ppm Fe), and second factor was rice genotypes (IR64, Margasari). The results showed the higher Fe concentration in the solution resulted in higher scores of iron toxicity symptoms, higher Fe levels in the plant, and caused stunted growth of rice plants. Levels of Fe in a solution of ≥ 200 ppm Fe inhibited plant growth. Iron toxicity symptom in Margasari was lower than the IR64 varieties, especially at concentrations of 200 and 400 ppm. According to the regression equation Y = 0.022X+ 1849, Fe concentration in the solution which caused light Fe toxicity symptom (score ≤ 3) was ≤ 52 ppm Fe, moderate (score = 5) was 143 ppm Fe, heavy (score = 7) was 234 ppm Fe, and severe (score ≥ 9) was ≥ 325 ppm Fe. Keywords: iron toxicity symptoms, iron concentration, rice

Observation and identification of rice germplasm with advanced traits are important activities in the process of obtaining a variety of rice because every genotype will show unique characters. Genotype derived from breeding program as anther culture need to be characterized to identify the doubled haploid lines that are potential to be developed in red rice breeding. This research was aimed to obtain agronomic characters of doubled haploid lines of red rice. Materials used were 59 genotypes, i.e., 57 doubled haploid (DH0) lines with red grain and 2 check varieties (Inpari 24 and Aek Sibundong) as control. The experiment used a randomized complete block design with three replications. The results exhibited there was agronomic variation among DH0 of red rice lines. Variance analysis showed that genotype affected most characters, except for grain dry weight per hill. Plant height, number of productive tiller, harvesting age, panicle length, number of grains per panicle, and number of filled grain per panicle can be used as a reference for effective selection to develop high productivity of red rice variety.

The imbalanced supply-demand of soybean is the main reason of soybean import in Indonesia. One of the efforts to increase of soybean production was expanding the planting area to acid soil with a low pH, high content of Aluminum, and low nutrient availability, through giving ameliorant, such as liming organic materials, and mineral fertilization.This study was aimed to obtain the best combination of fertilizer and amelioran for soybean production in acid soil. The study was conducted in experimental station of Tenjo, Bogor from November 2015 to March 2016. The experiment used a randomized complete block design with two factors. The first factor was combinations of fertilizer and amelioran, i.e., P0 (without fertilization); P1 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) ha-1}; P2 {25 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 1,250 kg of manure ha-1}; P3 {50 kg urea + 75 kg SP-36 + 50 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P4 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ¼ x Aldd (805 kg) + 2,500 kg of manure ha-1}; P5 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) ha-1}; P6 {75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomites 1 x Aldd (3,220 kg) ha-1}. The second factor was soybean varieties of Tanggamus and Anjasmoro. The results showed that application of 75 kg urea + 150 kg SP-36 + 100 kg KCl + dolomite ½ x Aldd (1,610 kg) produced the highest productivity (2.91 ton ha-1), but it was not different from reducing the dose of dolomite into ¼ x Aldd (805 kg) with the addition of 2,500 kg of manure.

ABSTRACT Sorghum is one of the potential foods with a higher protein content than rice. Sorghum seeds can be milled and cooked as sorghum rice. This study was aimed to obtain information on the inheritance of morphological and agronomic characters from the population derived from crosses of wide genetic background. The study consisted of the formation of F1 population and evaluation of morphological and agronomic characters in the segregated population (F2) of the three selected F1 genotypes. The location of the research was at IPB Experimental Field, Leuwikopo. The performance of the F1 genotypes were between the two parents, except for the yield components of PI-150-20-A x Numbu and PI-150-20-A x Kawali were higher than the parental lines. The performance of the F2 generation population was also between the parental lines, but with a wider distribution. The sorghum seed color is controlled not only by additive and dominant gene action, but also by epistatic gene action. The character of seed weight per panicle is controlled by epistatic gene action. In the F2 population of the crosses of PI-150-20-A x Numbu and PI-150-20-A x Kawali and PI-10-90-A x Numbu, the seed weight character is inherited with moderate heritability value. Based on genes action dan heritability, bulk or single seed descent method are suitable for yield improvement of the populations.Keywords: gene action, heritability, seed color, segregation, sorghum

Most of marginal lands in Indonesia are in the form of acid dry land with low available P and high Al concentrations. Development of tolerant rice varieties to P deficiency and Al toxicity is one way to increase rice production. This study aimed to select BC3F1-Pup1+Alt genotypes from three crosses based on foreground and background markers. This research was conducted at the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development, Bogor, from August to December 2015. The materials used were 300 genotypes of BC3F1 Dodokan-Pup1+Alt, BC3F1 Situ Bagendit-Pup1+Alt, BC3F1 Batur-Pup1+Alt, and the parents. The research included selection in modified Yoshida’s nutrient solutions (0.5 ppm P dan 60 ppm Al) followed by foreground selection and background selection. Selection using Yoshida’s nutrient solution resulted in 150 genotypes with longer root than the recipient parent in each of the BC3F1 populations. Selection with foreground markers using markers RM1361 and RM12031 produced 85 genotypes of BC3F1 Dodokan-Pup1+Alt (56.6%), 105 genotypes of BC3F1 Situ Bagendit-Pup1+Alt (70%), and 77 genotypes of BC3F1 Batur-Pup1+Alt (51.33%). Selection using background markers revealed that genotype number 116 (BC3F1 Dodokan-Pup1+Alt), number 2 (BC3F1 Situ Bagendit-Pup1+Alt), and number 129 (BC3F1 Batur-Pup1+Alt) were the best genotypes with percentage of parent recovery of 95%, 90%, and 90.5%, respectively. These three genotypes were verified to have Alt loci and had the largest genetic proportion of restoring parents. Keywords: Alt, background markers, foreground markers, Pup1, upland rice
