| 摘 要： | 为了解决杂交粳稻主要品质性状的选育问题,选用5个BT型不育系和40个三系粳稻恢复系,采用p×q不完全双列杂交(NCⅡ)设计,配制200个杂交组合及其亲本为试验材料,对F1品质性状的杂种优势、配合力及遗传力进行分析.结果表明:(1)除长/宽外,其余10个品质性状均有一定程度的超高亲优势,11个品质性状均有一定的正向均亲优势;(2)糙米率、精米率、整精米率、垩白粒率、垩白度、粒长和直链淀粉含量等7个品质性状的遗传以加性效应为主,粒宽、长/宽、碱消值和胶稠度等4个品质性状的遗传以非加性效应为主;(3)除了粒长和长/宽以外,其他9个品质性状受恢复系影响较大;(4)各品质性状狭义遗传力的大小顺序依次为垩白粒率＞垩白度＞整精米率＞精米率＞直链淀粉含量＞糙米率＞胶稠度＞粒长＞碱消值＞长/宽＞粒宽.
