摘要
本文对14个冬、春性小麦品种的主要性状在南北两地的遗传表现进行了比较研究。结果表明:两种环境条件下小麦主要性状对单株粒重的作用趋于吻合,南北两地小麦育种在性状遗传、相关和选择方向上具有一定的共性。通过聚美分析把供试材料分为不同的生态类群,分类结果与育种实践相一致。
The contribution of main traits to the weight of grains per plantunder the two locations was identical.The main traits inheritance,correlat-ion and selection showed certain general characters in wheat breeding inboth areas.The materials studied were classified into different groups withdifferent ecological types.
