Gene Effects for Agronomic Characters of Upland Cotton (Gossypium Hirsutum L.) in Korea

Six populations-P₁, P₂, F₁, F₂, B₁ and B₂-each of three upland cotton(Gossypium hirsutum L.) crosses were used to evaluate gene effects in the inheritance of six useful agronomic characters by Gamble’s six-parameter model for the analysis of generation means. The additive gene action governed the staple length and lint percentage, so that the individual selection for these characters in F₂ generation will be very valid steps. Since the additive gene actions of boll weight and days to flowering were equal to the dominant gene actions of these, since the number of bolls per plant and lint yield per plant were governed by the dominant gene actions, there are hopeful that the desirable types for those characters will be selected by the effective steps, according to increasing the additive gene effects of those in the following generation.
