摘　　要：杂交粳稻不育系异交结实差导致杂交粳稻繁殖制种产量低是杂交粳稻发展缓慢的一个重要原因。综述了杂交粳稻不育系异交结实研究进展和高异交结实率粳稻不育系育种成果。重点介绍了杂交粳稻不育系柱头外露和早花时2个有利异交结实性状的研究进展,同时还介绍了环境条件和父本特性对提高杂交粳稻繁殖制种产量的重要性。为选育高柱头外露率、早花时等有利异交结实的粳稻不育系提供参考,促进中国杂交粳稻跨越式发展。The low yield of male sterile line multiplication and hybrid seed production due to poor outcrossing of male sterile lines is an important reason for the slow development of japonica hybrid rice.The research progress of outcrossing of male sterile lines and the breeding results of high outcrossing male sterile lines in japonica hybrid rice were reviewed.This paper focused on the research progress of high stigma exsertion rate and early flowering time,two favorable outcrossing traits of male sterile lines,and also introduced the importance of environmental conditions and male parent characteristics in improving the yield of multiplication and hybrid seed production of japonica hybrid rice.The results would provide a reference for developing japonica male sterile lines with high stigma exsertion rate and early flowering time which are favorable to improve outcrossing,and promote the leapfrog development of japonica hybrid rice in China.
