【Abstract】 Three kinds of insects were used to pollinate for cytoplasmic male sterile lines of soybean in a man made big room covered with net. The results showed that the honey bee ( Apis mellifera ligustica spin.) was the best pollination medium. It greatly increased the number of pods and seeds generated by one single plant compared with the sterile line in open field. The pod generation rate, seed generation rate and per plant’s yield ratio were as 10.5, 12.8 and 11.8 times as those of sterile lines in open field with no honey bees, respectively. Especially, the sterile line’s average yield was about 488.4kg/hm 2. But there was no significant difference among the treatments of spraying sugar, blowing, putting color silk lines and CK (no treated). And there was no active pollination effect by ants and flies, either.更多还原
