摘要:
为探明品种复壮前后的性状区别及其对应的基因型变化,对种性严重退化的云南香软型水稻品种滇屯502及其复壮品种滇屯506进行研究,分析复壮品种滇屯506的农艺和品质性状及其主要性状基因位点的差异。结果表明,与滇屯502相比,多个生态环境条件下复壮品种滇屯506在全生育期、株高、穗长、穗粒数、谷粒大小等性状上无显著差异,在单位面积有效穗数、结实率和单位面积产量的性状上显著提高,稻瘟病抗性明显提高,达到抗性级水平,其稻米具有香味,米饭软而不回生。对与生育期、株型、品质、产量、抗逆性相关的63个基因位点检测结果显示,2个品种仅有3个基因位点存在差异。发现滇屯506携带稻瘟病抗性基因Pid3和Pi5,稻瘟病抗性提高,提高了结实率和产量,且滇屯506仍携带香味基因badh2和低直链淀粉基因Wxhp,保留了米饭香软的特性和优良食味品质。基因型检测结果与田间性状表型一致,同样表明复壮品种滇屯506稻瘟病抗性提高,恢复了生产力,品质没有下降。本研究结果可为香软型水稻品种复壮提供数据参考。
