QTL Mapping of Chalkiness Using Chromosome Single Segment Substituted Lines in Rice
摘要
Abstract
In order to evaluate and mapping QTL associated with Chalkiness and then analysis their genetic effects,84 chromosome single segment substitution lines ( CSSSLs ) were derived from the cross of Guangluai 4 as recipient line and Nipponbare as donor line .One-way ANOVA and Dunnett′s test were employed to detect 36 QTLs (P≤0.001) associated with chalkiness,in which 19 were degree of endosperm chalkiness (DEC) related QTLs. The additive effects ranged from -6.44 to 12.86, and the additive effect contributions were -34.04%-68.02%. The other 17 QTLs were associated with percentage of grain with chalkiness ( PGWC) .The additive effects of them were-7 .32-3 .63 and the additive effect contribution were -8 .07%-4 .00%.These results provided useful in-formation for fine mapping and cloning related QTLs ,and will facilitate the improvement of rice appearance quality.关键词
