Abstract:

S0105, a soybean cytoplasmic-nuclear male sterile line, was used as female parent to test cross with 280 cultivars from home and abroad in different latitudes and ecological zones. The results showed that when the fertilities rate of pollens were over 90 percent, the plant was fertile. According to both fertilities of pollens and plants of F₁, 9 restorer lines (restoring rate ≥97%) were selected. Crossed with the sterile line, superparents and superstandard heterosis appeared in all the 9 crosses by the seed yields of their F₁. Furthermore, 4 crosses showed over 25% of both heterosis.
