摘要
在杂交水稻制种中,高柱头外露率不育系可有效提高杂交种产量,降低生产的单位成本,受到广大种业公司的欢迎。因此,对水稻(Oryza sativa L.)柱头外露率进行研究具有重要的意义和广泛的市场需求。对近年来发表的在水稻柱头外露率的遗传和环境因子,以及高柱头外露率水稻品系育种实践的探索进行了综述。
In hybrid rice seed production, the high stigma exsertion rate of a male sterile line is welcomed with Seed Company for higher yield and lower cost. Therefore, the study of stigma exsertion has significance for raising the yield of hybrid seed production. In this paper, we reviewed the genetic and environmental factors influencing the stigma exsertion rate, and the practices of breeding rice lines with high stigma exsertion rate.
