Abstract

This experiment was performed to obtain the basic information on heterosis and heterobeltiosis of quantitative characters in the eggplant by crossing of varieties. The heterosis and heterobeltiosis were estimated in Fl generation. The results were as follows, based on the graphical analysis, the characters, plant height, stem diameter, fruit weight, leaf length, leaf width, and fruit number per plant(yield) were assumed to inherit dominance, and fruit length and fruit diameter were found to inherit incomplete dominance. The degree of positive heterosis of plant height, stem diameter, fruit weight, fruit length, fruit diameter, leaf length, leaf width, and fruit diameter, leaf width, leaf length, fruit weight, and stem diameter showed negative heterobeltiosis.

가지 육종을 위한 기초 자료를 얻고자 9품종을 교잡하여 $F_l$ 세대의 11개 조합을 재료로 각 형질들의 측정치로서 우성의 정도와 잡종강세를 평가하였다. $F_l$세대의 잡종강세는 초장, 경경, 과중, 엽장, 엽폭, 주당과수 등이 초우성으로 유전되었다. 그리고 과장과 과경은 불완전 우성으로 유전되었다. Heterosis의 정도는 초장, 경경, 과중, 과장, 과경, 엽장, 엽폭, 주당과수 등 8개 형질 모두에서 정(+)의 강세를 보였다. Heterobeltiosis의 정도는 초장만이 정(+)의 강세를 보였고, 과경, 엽폭, 엽장, 과중, 주당과수, 과장, 경경은 부(-)의 잡종강세를 보였다
