沈农系列水稻高产品种及其衍生系的遗传结构分析
Structure Analysis of High-yielding Rice Varieties and Their Derived Lines Bred by Shenyang Agricultural University
摘要
Abstract
Six high-yield varieties (Shennong 265 ,Shennong 606,Shennong 9741 ,Qianchonglang 1 ,Shennong 9903, Shennong 981 6)and 570 inbred lines were used as materials to analyze the utilization of seven cloned yield-related functional gene (DEP1 ,GS5 ,qSW5 ,Gn1a ,qGW8 ,GS3 and GW2 )and the contribution of indica blood in the japonica rice breeding of Liaoning Province.The results showed that allelic variations were detected from all of the functional gene loci except for GW2 .The loci of DEP1 ,qSW5 and qGW8 were widely used in japonica rice breeding by the breeders at Shenyang Agricultural University.In the 570 inbred lines,467 lines (82.1 3% of the lines)contained DEP1 ,550 lines (96.5 % of the lines)contained qSW5 ,and 35 1 lines (6 1 .6% of the lines)contained qGW8 .The functional alleles of GS5 ,Gn1a and GS3 were also present in a small number of lines,and the rates were 5 .44%, 0.70% and 1 .05 %,respectively.The results of the analysis with 32 indica-japonica specific markers showed that indica-japonica differentiation on these sites existed in 54.0% of the lines.Most of the indica genetic loci were located on chromosome 5 ,with a percentage of 20.8%.关键词
