영문 초록

Cytoplasmic male-sterility line was found by Shiga in Japan. We have investigated the degree of heterosis of agronomic characters and ability of fertility restoration of F₁ from the cross between cytoplasmic male-sterilie line and 157 varieties as pollen parents of Korea, Japan and Europe. That result has appeared with highly desirable heterosis, particulary in yielding and most yield component characters except on 1,000 seed weight but plant height was tall and maturing was late. Ability of Fertility restoration of F₁ hybrids from Europe pollen parent varieties was 74% but that of Japanese pollen parent varieties was low as 5%. It seems that high yielding of F₁ from fertility non-restoration varieties may be caused by the polly cross.
