早熟恢复系DR02生育期特性的遗传分析
Inheritance of a Growth Characteristic of Precocious Restorer Rice Line, DR02
摘要
Abstract
A dominant early maturing trait was identified in DR02 rice bred from T251 and 02K511.Heading dates of the hybrid progenies from DR02 crossed with 6 medium or late maturing varieties, including Minghui 86 and Minghui 63, were analyzed to study the inheritance of the growth characteristic.It was found that the heading dates of F1 progenies were earlier than those of their mid-parents.The heading dates of F2 populations from DR02 crossed with Shuangkangmingzhan and 9311 had twin peaks, while those of F2 from DR02 crossed with the other 4 parents exhibited a unimodal distribution with closely clustered values.The segregation ratio between the early heading and the late heading plants was 3∶1 for the F2 population of DR02 crossed with Yuejingsimiao 2 and Shuangkangmingzhan, while those of other combinations were significantly and extremely significantly different.It suggested that the early maturing trait of DR02 could be largely controlled by a single relatively dominant QTL.关键词
