영문 초록

Nature of gene action and inheritance of the days to flower in mungbean (Vigna γ-adiata (L.) Wilczek) were determined in the F₁ and F₂ generations of 30 possible combinations of six-parent diallel cross. All the F₁ populations were grown in the pots(1/5,000a) under three different day length conditions (natural, 9-hour and 16-hour photoperiods). The F₂ populations were grown under two different plantings, early and late, in the experimental field of Crop Experiment Station, Suweon, Korea in 1984. The analysis of degree of dominance on the days to flower showed partial-to over-dominance, but the direction of dominance varied with different cross combinations. Early flowering in F₁ generation appeared to over-dominance over the late flowering under 9-hour photoperiod with no general tendency under natural and 16-hour photoperiod. Combining ability analysis indicated that both additive and non-additive gene action were involved in the days to flower. The estimation of broad sense heritability was considerably high for the days to flower (78.3%). The heritability estimates and F₂ distribution suggested that the photo-sensitive factor of V1094, which is photo-insensitive genotype was not expressed due to recessive inhibitor factor.
