棉花细胞质雄性不育的胞质效应研究现状及未来展望
Current status and future prospects of cytoplasmic effects of cytoplasmic male sterility in cotton
摘要
Abstract
Cotton has obvious heterosis,which is manifested in traits including yield,fiber quality,and resistance to diseases and insects.Hybrid seed production is a very important step in the utilization of cotton heterosis.Recently,as the cost of manual pollination in seed production increases year by year,the simplified,efficient,and low-cost seed production techniques have become an inevitable trend for future hybrid cotton development.The field practice shows that the use of cytoplasmic male sterile lines not only simplify the procedure of seed production but also save labor costs,so it has become a research hotspot in the utilization of crop heterosis.However,the sterile cytoplasm does have certain impacts on cotton morphogenesis,anther development,yield formation,fiber development,and have negative effects on cotton growth and development,thereby limiting the further promotion and utilization of"three-line(male sterile line,maintainer line,and restoring line)"hybrid cotton.In this paper,the effects of male sterile cytoplasm on the main traits of cotton and the molecular basis for its negative effects were systematically reviewed.And the potential ways to overcome the negative effects of male sterile cytoplasm in cotton were preliminarily discussed,which would provide new ideas for breeding and improvement of cotton cytoplasmic male sterile restorer lines and excellent"three-line"hybrids in the future.关键词
