Agronomic Trait Combining Abilities and Correlation with Yield of New Male Sterile Rice Lines

  • 摘要:   目的  探究五良A、酒都A、Z1A和1281A 4个新选水稻不育系主要农艺性状的配合力,同时分析不同农艺性状对产量的影响。  方法  采用6×6 NC Ⅱ遗传设计,利用6个不育系(S)和6个恢复系(R)杂交配组36个组合,对杂交组合的8个农艺性状进行配合力分析、相关及通径分析。  结果  (1)8个农艺性状在不育系或恢复系或两者间的一般配合力方差均达到显著或极显著水平,除株高外其他7个农艺性状的特殊配合力方差均达到显著或极显著水平,说明多数农艺性状受到加性效应和非加性效应共同影响。(2)株高、穗长、千粒重和每穗颖花数等4个性状广义遗传率较高,主要受到遗传的影响,其中株高、穗长和千粒重的狭义遗传率也较高(>70%),三者主要受到基因加性效应的影响,结实率、单株有效穗数和单株产量的狭义遗传率相对较低(<50%),表明这些性状受到基因非加性效应和环境的影响较大。(3)相关分析结果表明,千粒重、穗长、单株有效穗数和结实率与单株产量呈显著或极显著正相关,通径分析结果表明,千粒重、单株有效穗数对单株产量的直接作用达到极显著正相关,农艺性状之间通过相互促进与制约来共同影响单株产量。  结论  4个新选不育系中,五良A、酒都A多数农艺性状的一般配合力和特殊配合力效应较高,具有较好的应用前景;在川南中籼稻区,千粒重和单株有效穗数是影响单株产量的关键因素。
