영문 초록

The nature of combining ability and the components of genetic variance were studied in a diallel set of six-parents in various generations. Mean square values of GCA were more greater than those of SCA for all eight charaters estimated. Degree of dominance for p[ant height and pods per plant showed more than 1 and additive portion in variance in components were more greater than heterosis portions for days to flowering, stem diameter, pods per plant, pod length, seeds per pod and 100-seed weight. Heritability estimates for days to flowering, plant height, pod length and 100-seed weight were high, but stem diameter, pod number per plant and seeds per pod were very low. Direction of dominance in plant height, stem diameter, pod length and yield were positive values. But pod number arid 100-seed weight were negative in F2 and F3. The effect of GCA were differ from parents, generations and characters, and the effects of SCA were also differ from parents, crosses, generations and characters.
