High-yielding variety is one of the targets in soybean breeding program. High-yielding variety could be developed through simultaneous selection. Simultaneous selection using selection index was more efficient than selection based on an individual trait only. Objective of the research was to select agronomic characters for construction selection index on 11 soybean populations F6 generation based on correlation analysis, path analysis, and heritability. The correlation analysis showed that number of branch, number of total nod, number of filled pod, number of unfilled pod, number of total pod, and percentage of filled pod have positively and significantly correlated with yield per plant. Based on path analysis, characters number of branch, number of unfilled pod, and number of filled pod have positive direct on yield per plant. The result also showed that number of filled pod has maximum positive direct effect on yield per plant. Generally, number of total nod, number of filled pod, number of total pod, and percentage of filled pod have higher heritability than other characters. Key words: Soybean, correlation, path analysis, heritability, selection index

A study was conducted to reevaluate 15 upland lines previously selected in a field experiment and nutrient culture experiment or tolerance to aluminum toxicity and potassium efficiency in the plastic house of Center for Crop Improvement Studies, Tajur, Bogor. The experiment was conducted in pot culture using Red Yellow Podzolic soil from Jasinga, Bogor. Two level of AI stress (no AI stress and AI stress with pH 4.8, Al saturation 80%, and exchangeable Al 16.6 mei/IOOg) and two levels of potassium fertilizer (6 kg K2Olha and 60 K2Olha) were applied. The study showed that the upland rice lines performed poorer under AI-tress condition compared to under non stress condition in plant heigl at harvest, total number of tiller, number of productive tiller, length of spikelet and grain weight/pot. The performance of the upland rice lines was also significantly different under different level of potassium fertilizer in total number off tiller and nun1ber of productive tiller. Lines that showed significant difference in its performance under AI-stress and non stress condition were consiidered as tolerant lines. The result showed that Lalantik Bamban, Sigundil,CT65 I 0-24-3- I, Hawara Bunar, Ketombol, and Grogol were classified as AI-tolerant and K-efficient lines. Key word: Upland rice, Aluminium, Potasium

Anther culture provides rapid route in obtaining pure lines in a single generation through producing green haploid plants that may be spontaneously doubled. This technique has been used for crop improvement especially in rice. The objective of this research was to determine regeneration ability of eight F1s derived from crossess between upland and new plant types of rice and from their four parents through anther culture. Completely randomized design with 25 replications was used in this research. Treatments consisted of four parent lines/varieties i.e. P1 (Fatmawati and BP360E-MR-79-2), P2 (Fulan Telo Gawa and Fulan Telo Mihat) and eight F1s obtained from reciprocal crosses of P1 and P2. Callus induction medium was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1 kinetin + 10-3 M Putrescine, while regeneration medium was based on MS + 0.5 mg L-1 NAA + 2.0 mg L-1 kinetin + 10-3 M Putrescine. The result indicated that F1 derived from Fatmawati x Fulan Telo Gawa (5.00% green plants per total anther) and their reciprocal (3.80% green plants per total anther) crosses were the most responsive genotypes in rice anther culture (had high anther culture ability). The F1 genotypes were more effective to produce green and doubled haploid plants in rice anther culture than their parents. From this research, 161 double haploid plants (29.81%) from total acclimated green plantlets were obtained. Keywords: anther culture, upland rice, new plant type of rice

A study on physiological mechanism of sorghum to aluminum (Al) toxicity and phosphorous (P) deﬁ ciencies was conducted using several sorghum genotypes in rhizotron. The study was conducted in the greenhouse of the University Farm, Bogor Agricultural University from August to October 2009. The experiment was carried out as a Factorial experiment in a Completely Randomized Design with three replications. The ﬁ rst factor was sorghum genotypes consisted of Numbu (tolerant) and B-75 (sensitive), and the second factor was combination of lime and phosphorous fertilization consisted of: no lime-no P (R1), no lime-low P (R2), no lime-sufﬁ cient P (R3), lime-no P (R4), lime-low P (R5) and lime-sufﬁ cient P (R6). The results showed that all variables were signiﬁ cantly affected by the interaction of media and genotype, except for length of shoot and total P uptake. Under low P and Al toxicity, sorghum variety Numbu showed a higher nutrient efﬁ ciency than B-75 with ability of forming greater dry mass. The sensitive genotypes showed a higher nutrient uptake but a lower P nutrient use efﬁciency under Al toxicity and P deﬁ ciency. Total P uptake and P nutrient use efﬁ ciency were highly correlated with root growth and dry material accumulation. Keywords: sorghum, Al toxicity, P deﬁ ciencies, P nutrient use efﬁ ciency, P uptake

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
