Analysis on Major Characters of the 73 Indica Hybrid Rice Combinations Registered in Fujian Province During 2008-2012

摘要: 对2008-2012年通过福建省审定的73个籼稻组合的主要特征特性进行分析,结果表明:审定品种中以三系杂交稻组合为主;配组使用的不育系数量较多。审定品种的产量水平较高,稻米品质得到较明显的改善,优质与高产性状得到初步协调.不育系对组合的抗瘟性影响较大;恢复系的配合力对组合的产量优势起着重要作用。讨论了加强优良组合选育的策略。Abstract: The major characters of 73indica varieties released in Fujian province from 2008to 2012were analysed. The results showed that the majority of registered varieties were three-line hybrid rice combinations,and many male sterile lines were used.Most of the combinations had a high grain yield and good rice quality,the quality and yield traits in rice were preliminary coordinated。The male sterile lines had great ffect on blast resistance of combination and the the combining ability of restorer line has important roles in yield heterosis.Base on these results,the strategis about combinations breeding were discussed.
