| 摘 要： | 以辽宁省近年来审定的水稻品种为分析材料,对辽宁省水稻不同熟期品种群体品质性状的多样性进行了比较和核心样本的初步构建。结果显示,中晚熟、晚熟品种群体整体多样性较大,中晚熟、晚熟品种群体的多数品质性状的多样性也较大。所建立的核心样本的多样性也有较大的代表性,同时,核心样本品种在育种的亲本选择上也有较大的参考价值。

| Abstract: | Taking rice varieties approved recently in Liaoning as entries,the diversity of quality traits of rice varieties with different maturity was compared and the core collection was built primarily.The results showed that there existed greater diversity in total and also in quality traits in mid-late and late maturity populations.The core collection was rep-resentative and had much more valuable reference for parental selection in breeding. |
