영문 초록

The objective of this study was to determine by using Hayman’s six parameter model whether epistasis played a significant role in the genetic systems for culm length among several winter wheat (Triticum aestivum L.) cultivars. Parents, F₁, F₂ and first generation backcrosses (B₁ and B₂) of five crosses were grown in the field of Wheat and Barley Research Institute in Suwon, Korea, from October, 1984 to June, 1985. There were some deviations between F₁s and their Mid-parent to suggest the presence of the considerably different degree of gene interaction of additive and non-additive depending upon crosses. Narrow-sense heritability estimates on culm length were very high for three crosses and moderate for two. GS(Gain from selection) of each cross ranged from 13 to 30%. Although additive and dominant gene action were considerable in most crosses, fitness of 3-parameter model was not significant for culm length of wheat crosses. Six-parameter model analysis showed that dominant x dominant epistasis, additive x additive epistasis and dominance gene action significantly affected the expression of culm length in most crosses.
