Inheritance of a Growth Characteristic of Precocious Restorer Rice Line, DR02

Sanming Academy of Agricultural Sciences, Shaxian, Fujian 365051, China

摘要

摘要: 水稻DR02来源于T251与02K511的杂交后代，具有显性早熟特性。以DR02分别与明恢86、明恢63等6个不同类型的中、迟熟水稻品种杂交后代进行遗传性分析。结果显示，各组合F₁的抽穗期均比中亲值早，DR02与双抗明占和9311的杂交F₂的抽穗期呈双峰分布，与其他4个亲本的F₂抽穗期呈单峰分布，用中亲值进行分组，经χ²测验，仅DR02与粤晶丝苗2号和双抗明占组合的F₂代分离比符合3：1，其他组合均表现显著与极显著差异，不符合预期理论比。综合上述分析结果表明水稻材料DR02的早熟性可能是由1个比较大效应的主效QTL控制的。

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.
