摘要:
【目的】研究小麦杂交F1代性状遗传变异规律及杂种优势,为筛选优良杂交子代提供参考。【方法】以邯5316为母本,6个不同小麦品种为父本的杂交组合及其母本为材料,利用方差分析、相关性分析和主成分分析等方法,分析7个表型性状。【结果】①小麦F1代性状存在丰富的遗传多样性,14个性状平均变异系数范围为4.00%~17.71%;②小麦F1代性状间的遗传传递力有差异,穗长、穗粒数、穗粒重和千粒重的遗传传递力最高,均大于100%;③性状中亲优势率为-32.95%~99.13%,且不同组合性状杂种优势不同;④7个性状均存在相互影响,且穗粒重、穗粒数和千粒重之间影响较大。【结论】筛选出18-4、18-5两个优良杂交组合,其子代具有穗长、穗粒数多、穗粒较大等特性。
