摘要
抽穗期是水稻(Oryza sativa)重要的农艺性状,它决定着水稻品种的地区和季节适应性。本试验利用以华粳籼74为受体亲本发展的带有抽穗期基因的15个单片段代换系为试验材料,通过两两杂交,筛选出15个不同亲本组合的双片段聚合系,结合分子标记辅助选择进行水稻抽穗期QTL鉴定,并研究QTL的聚合及其互作关系。
Heading date is an important agronomic trait in rice(Oryza sativa),which decides the variety adaptability of cultivation areas and seasons.Taking 15 single segment substitution lines which developed from Huajingxian 74 and carryed heading date gene as materials,after crossing them in pairs,15 double segment pyramiding lines were selected to identify the quantitative trait loci(QTL) for heading date by marker- assisted selections,and the pyramiding and interacting effects of QTL were also studied.
