목차

In order to obtain basic genetical information in pea(Pisum sativum L.), a series of field experiments were carried out with seven typical pea cultivars and F₁ hybrid lines for three years. Based on the information collected from a set of diallel crosses, the behaviours of inheritance of seed yield and othe then major agronomical characters were observed by the distribution of genes and degree of dominance.
Based on the Vr-Wr graphical analysis, the characters, days to flowering, stem length, stem diameter, pod length, number of seeds per pod and 100-seed weight, were found to inherit incomplete dominance, and the characters of number of pods per plant, number of seeds per plant and seed weight per plant were assumed to inherit overdominance.
Based on the estimation of gene frequency, the cultivars having such characters as late flowering, heavy seed weight, and long stem length were found to have a number of useful genes in the characters of days to flowering, stem length, pod length, number of seeds per plant, 100-seed weight and seed yield.
