The efectiveness of selection depends on the gene action cotrolling the character. The presence of epistatic gene action will delay the genetic gain in self pollinated crops like soybean. The objective of this research was to obtain information on genetic control of soybean tolerance to aluminum toxicity on nutrient culture. This research was conducted at green house of the University Farm IPB Cikabayan, Bogor, from April to June 2013. This research used 120 seedlings of F2 population generated from crossing between Argomulyo (Al-sensitive) with Tanggamus (Al-tolerant). Seedlings were grown in nutrient culture for 14 days with Al concentration of 1.5 mM and pH 4.0, to observe the vegetative growth under aluminum stress condition. The result showed that mean of roots length, shoot length, shoot to root ratio, wet and dry weight of root and shoot exceeded both parents mean value with moderate to high heritability. All observed characters had continue distribution pattern, and controlled by many genes. Duplicate epistasis additive gene action controlled only root length while other characters were controlled by complementary epistasis gene action.Keywords: gene action, heritability, nutrient culture, selection, tocixity

Pedigree selection is a method of selection used in segregating populations which takes the expertise of breeders in achieving the desired goal. This method is implemented on the early generations with a high degree of segregation and is generally performed on highly heritable traits. The purpose of this research was to study the performance of F3 generation segregants and to estimate the genetic parameters to be used for identification and selection of wheat segregants under optimum environmental condition. The research was carried out at the experiment field of Research Institute for Ornamental Crops, in Cipanas from May to September 2012. Genetic material used were 58 F3 family and six check varieties, namely Dewata, Selayar, Oasis, Rabe, Basribey, and HP 1744. The experiment used an augmented design. Results of analysis of variance showed that the family effect was significant for days to flowering, days to harvest, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant and seed weight per plant. High heritability estimates were found in days to flowering, days to harvest, seed filling period, percentage of empty florets, number of grains per panicle, grain weight per panicle, number of seeds per plant, and seed weight per plant. These characters are suitable for yield improvement of tropical highland wheat due to its high heritability values. The mean value of F3 generation changes subsequent to selection either based on grain weight per plant, or based on number of productive tillers, number of grain per panicle, and grain weight per plant. Keywords: selection criteria, segregation, tropical, yield

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
