粳稻02428×02428c重组自交系孕穗期耐冷性QTL分析
QTL Analysis of Cold Tolerance in Japonica Rice Using Recombinant Inbred Lines from 02428 × 02428c at Booting Stage
摘要
Abstract
A cold-sensitive japonica rice variety 02428 and a cold-resistant rice variety 02428c were used as parents to produce an FS|, population composed of 336 recombinant inbred lines. Numbers of filled grains, unfilled grains, total grains and seed-setting rate were measured as phenotypic values for evaluating cold tolerance at the booting stage. A genetic linkage map was constructed with 486 SSR markers for QTL mapping. The markers RM6092, RM6702, RM5954, RM1095, RM1183, RM7643 and RM3411 were linked to the cold tolerance at the booting stage. Three QTLs controlling cold tolerance at the boo ting stage were identified on the chromosome 1 with QTLMapper 1. 6.关键词
