水稻抽穗期基因Hd7m的定位及遗传分析
Mapping and Genetic Analysis of Heading Date Gene Hd7 m in Rice
摘要
Abstract
Using Hongqi 16 as the receptor and Minghui 63 as the donor, a BC4 F1 segregation population was developed through cross between the two parents and backcross with Hongqi 16.The early heading gene pool, late heading gene pool, and the parents were analyzed with 643 pairs of SSR markers, and 4 pairs of polymorphic markers were obtained.BC4 F2 populations derived from inbreeding of BC4 F1 hybrid plants with obvious segregation phenotype were selected for field investigation and genotype detection.The results showed that the target gene, named Hd7m, was linked to SSR marker PSM391, which located at the end of chromo-some 7.Based on the targeted interval, 10 pairs of new SSR markers were synthesized.Among which, the polymorphic marker RM22156 was apart from Hd7m of 4.1 cM.The results laid foundations for fine mapping, gene cloning and molecular marker assisted breeding of Hd7m.关键词
