1 BL/1 RS易位系小麦品质性状相关基因等位变异分析
Analysis on Allelic Variation of Quality-related Gene in 1 BL/1 RS Translocation Wheat Cultivars
摘要
Abstract
In order to analyze utilization value of 1BL/1RS translocation in wheat quality breeding,the allelic distribution of five quality-related genotypes,Ppo-A,Ppo-D,Psy-A,Pinb-D1 and Vp-1,in 258 1BL/1RS translocation wheat cultivars(lines)were detected using molecular makers of these genes. In 258 1BL/1RS translocation wheat cultivars(lines),the distribution frequency of Ppo-A1b and Ppo-D1a were 58. 2% and 64. 0%. The allelic combination of Ppo-A1b/Ppo-D1a occupied 36. 8%. The results showed that 1BL/1RS translocation lines could be used in the low-PPO-activity wheat breeding. The frequency for the allele of low yellow pigment,Psy-A1b,was 30. 2%. In low-yellow-pigment wheat breeding,1BL/1RS translocation lines should be selected carefully. The percentage of Pinb-D1b allele was 60. 9%. In 258 1BL/1RS translocation wheat cultivars(lines),27 belonged to the allelic combination of Ppo-A1b/Ppo-D1a/Psy-A1b/Pind-D1b. The 27 cultivars were important in wheat quality breeding. The frequencies of ear sprouting related genes Vp-1Ba,Vp-1Bb,and Vp-1Bc,were 33. 3%,3. 1% and 63. 6%.关键词
