超级稻品种中嘉早17产量相关性状 QTL 定位研究
QTL Mapping of Yield Related Traits in Super Rice Variety Zhongjiazao 17
摘要
Abstract
The rice yield related agronomic traits were examined,and the genetic linkage maps were constructed with the F2 populations derived from Zhongjiazao 1 7 × D50.A total of 66 QTLs for yield related traits were mapped,with the contribution rate ranging from 0.08%~20.45 %,distributed on all the 12 chromosomes except for chromosome 9. Numbers of QTLs for yield related traits were mapped in the same intervals on Chr.3,Chr.7 and Chr.10,respectively, in F2 or F2 ∶3 populations,and the positive alleles were contributed by Zhongjiazao 1 7.Among the mapped 66 QTLs, these detected in both F2 and F2 ∶3 populations with high contribution rate include qP H-10 ,qFLW-4 ,qTGW-2 ,of which the positive alleles were also contributed by Zhongjiazao 1 7.In total,66 QTLs for yield related traits were preliminarily examined in super rice variety Zhongjiazao 1 7,which will provide theoretical and technical supports to breed new super rice varieties with higher yield and better comprehensive characteristics by transfering excellent genes from Zhongjiazao 1 7 into other rice varieties.关键词
