摘　　要：利用粳稻台中65及其F1花粉不育近等基因系和它们的F1作研究材料,对这些遗传背景基本相同但具有不同F1花粉不育基因座位材料进行花粉愈伤组织诱导率及花药开裂性的研究.结果为:亲本与杂种在离体条件下的花粉愈伤组织诱导率无显著差异,杂种F1花粉部分败育并未导致花粉愈伤组织诱导率下降,表明F1花粉不育基因与花粉愈伤组织诱导能力性状无直接联系;但亲本与杂种间的花药裂药性却存在显著差异,并随着花粉败育率的提高花药开裂率下降,表明F1花粉不育基因与花药开裂性状有关.Japonica rice Taichung 65 and its pollen sterile near-isogenic lines were used to study the function of specific-compatibility gene in vitro in order to further perfect the academic viewpoint. By the studies, the main results were as follows: During the anther culture, there were no obvious differences in the pollen callus induction ability between the recurrent parent and their F_1. It meant that the pollen sterility genes which lead to the pollen abortion in vivo might not lead to the decrease of the pollen callus induction ability in vitro. But there was a distinct difference in anther dehiscence between the recurrent parent and their F_1. The lower the pollen fertility was, the worse anther dehiscence was. The character of anther dehiscence might connect with the pollen abortion.
