Genetic Studies on Some Quantitative Characters of Adzukibean by the Diallel Crosses Ⅰ. Distributions of Genes for Various Characters in F1 and F2 Generations

A set of 36 crosses of F₁’s and F₂’s from nine Adzukibean varieties(Yeongdong Jeogdu, Gongju Baegdu, Gyeonggi Gaeguri, Wase Dairuyu No.1, Natsu Adzuki, Maruba No.1, Jeogdu, Nesumi Mochi and Hongcheon Jeogdu) were grown in the field for estimating gene distribution and degree of dominance. From a series of experiments conducted in 1981 to 1982, five agronomic characters (day to flowering, plant height, pod numbers per plant, 100-grain weight and grain weight per plant ) were observed. Partial dominance was observed in days to flowering, pod numbers per plant, 100-grain weight and grain weight per plant, and over dominance was found in plant height in F₁’s and F₂’s. But days to flowering in F₂’s, plant height in F₁’s and grain weight per plant in F₁’s were rather found to be inherited in completed dominance.
