不同温光条件下水稻抽穗期QTL的定位与分析
QTL Analysis for Heading Date in Rice (Oryza sativa L .) Under Different Temperatures and Light Intensities
摘要
Abstract
QTLs for heading date were identified with 85 rice chromosome single segment substitution lines (CSSSLs) derived from Nipponbare as donor parent in the background of Guanglu’ai 4 ,for means comparisons between CSSSLs and the recipient parent Guanglu’ai 4 by one‐way analysis of variance and Dunnett’s test .A total of 40 QTLs for head‐ing date were identified on all 12 chromosomes under two different temperatures and light intensities with a significance of P≤0 0.01 .Twenty‐one QTLs for heading date were mapped in the two environments ,15 QTLs only in Nanjing ,and four only in Sanya .Thirty‐six QTLs were mapped in Nanjing ,the additive effects of which ranged from 2.8 d to 15 7. d ,the additive effect percentages from 3 8.% to 21 1.% ;25 QTLs were mapped in Sanya ,the additive effect of which ranged from 1 8. to 12 1. d ,the additive effect percentages from 1 7.% to 11 3.% .The results are important for the QTLs cloning and breeding of new high‐quality rice variety in different environments .关键词
