Soybean is one of the crops that produce seeds with high protein content, as well as used by the inhabitants of Indonesia. Domestic soybean production can not meet the needs of the national soybean thus needs to be improved, one through breeding varieties with superior. One important step in plant breeding is the selection. To save time and costs of selection, it is necessary to determine the estimated correlation between characters and to determine the causal relationship between characters used path analysis. Through path analysis can be seen directly and indirectly influence between variables forecaster with the response variable. The purpose of this study to obtain information (1) correlation between characters agronomic towards production. (2) direct and indirect effects of agronomic between characters towards production. The research was conducted from October 2013 until January 2014 in the integrated field laboratory of the Faculty of Agriculture, University of Lampung and observations made in Laboratory of Seed and Plant Breeding, University of Lampung. Soybean seeds used were F5 generation zuriat from Wilis x Mlg 2521, Willis and Mlg 2521. The treatment laid out in a randomized block design, 2 replications. The results showed that there was a positive phenotype correlation between character of days to flowering, plant height, number of branches, number of pods, weight of 100 grains with grain weight per plant and there was no correlation between day to harvesting with the seed weight per plant. Direct selection of the most effective was through the number of pods because number of pods have a direct effect almost equivalent to the correlation. The relationship between the number of pods and weight of seeds per plant explained a real relationship. Keywords: correlation, path analysis, selection, soybean

The purpose of this study was to determine the amount of genetic diversity and phenotype, heritability in a broad sense as well as the numbers of soybean expectations F5 generation from crosses Wilis × B3570 which has a middle value the better of both parents. The experimental design used randomized group design by three replications. Genotypes were tested as much as 25 genotypes. he results showed that the amount of genetic diversity of soybean agronomic characters F5 generation from crosses Wilis x B3570 found in almost all the characters except the characters age observed flowering and harvesting age. The genotype diversity found in all agronomic characters were observed. The magnitude of the high heritability values found in the character of a weight of 100 grains. Heritability values were on plant height, number of productive branches, and the total number of pods. Character weight of seeds per plant, flowering age, and time of harvest had the lowest heritability. Numbers expectation obtained by the genotypes number 163-1-4, 130-2-11, 130-2-11, 163-1-15, 102-3-2, 163-1-1, 140-1-15 , 163-1-6, 181-5-4, 140-1-2 are rated according to the weight of the weight of seeds per plant that would refer to the high production Kata kunci: variability and heritability, and Soybean

Soybean is an alternative stapple food which use by all people in Indonesia. However,domestic soybean production does not meet the needs of the national soybean. To meetthe needs done, it important to assemble the soybean breeding to improved the noblevarieties. Plant breeding is largely determined by the ability of breeders to select.Selection can be done by estimating the correlation coefficient between thecomponents of the results and outcomes. To determine the causal relationship betweenyield and yield components used path analysis. Path analysis of correlation coefficientwill break into the direct and indirect influence. The purpose of this study are todetermine (1) the correlation between the components of the results and outcomes; (2)direct and indirect influence between the components of the results and outcomes. Theexperiment was conducted from March to July 2014 in field trials of POLINELA(Lampung State Polytechnic) and in Seed Laboratory of University of Lampung.Soybean seed used is the result of crossing Wilis F6 generation x B3570. Treatmentarranged in a perfect randomized group design with two replications. The results ofcorrelation analysis showed correlation great and positive value indicated by thecomponent total number of pods per plant and grain weight per plant (0.80 *),hundred grain weight and grain weight per plant (0.72 *), and the number ofproductive branches and grain weight per plant (0.57 *). Results of the analysisshowed cross large direct effect on the character of the total number of pods per plantto grain weight per plant (0.89), which is almost as large as the correlation (0.80 *).Then the correlation coefficient was actually measure the degree of closeness of theirrelationship. Therefore, the selection is based on the total number of pods will be veryeffective to get genotype expectations that have high yields.Keywords: Soybean, Selection, correlation, analysis of cross

The objective of this study was to evaluate the resistance to cowpea mild motlle virus (CPMMV) of 19 F1 population of soybean showing good agronomic characters. The F1 population were generated by complete diallel crosses involving a resistant parent (Mlg 2521), a moderately resistant parent (B 3570), and three susceptible parents (Orba, Wilis, and GKUL-1). The experiment was arranged in a completely randomized block design consisted of two replications. The results indicated that F1 population B 3570 x Mlg 2521 was resistant to CPMMV and superior in seed weight per plant, number of branches, plant height, total number of pods, total number of seeds, and the number of healthy seeds. F1 population Wilis x B 3570 and B 3570 x Wilis were moderately resistant and less superior in agronomic characters than B 3570 x Mlg 2521.Key words: CPMMV, diallel, Glycine max,viral resistance

Experiments were conducted at farm area Gedung Pakuon village?s Kecamatan Baradatu Kabupaten Way Kanan ? Lampung and the Laboratory of Seed of Lampung University, on April 2009 to Januari 2010. In the first experiment used P1 (brown/C), P2 (black), dan F1 (C x H), to have seed for planted on the second experiment. In the second experiment the population of P1 (coklat), P2 (hitam), F1 (C x H), F1 resiprok (H x C), BC1 (F1 x C), BC2(F1 x H), dan F2. Were tested to estimasi number of controlling gen, gene action, and maternall effect. The character were observed i.e. the colour of seed skin and the colour of pods. The result showed that F2 population in the colour of pods were not normal distribution, and base on estimated number of gen this character was controlled by 2 genes with inheritance controlled by a simple gen. Inheritance pattern of the colour of seed skin have complex equivalent, and segregation in F2 population. The colour of pods with mendelian ratio of 12:3:1 (dark green : green : bright green). Result of experiment to maternal effect indicated that there was maternal effect in the the colour of seed skin, but not in the colour of pods.Key Words: yardlong bean, maternall effect, heritability
