高产、多抗、优质是小麦育种的总目的,以品种所需达到的各主要农艺性状为指标。为此,本文采用高产次数分布频率分析法探讨小麦高产(500KG/667平方米)品种的穗粒结构、主要农艺性状的具体指标和高产育种途径。材料和方法用本所1981—1990年度南方冬麦区、湖北省区域试验、襄樊市小麦新品种(系)区域试验和本所小麦 High yield, multi-resistance, high quality is the general purpose of wheat breeding, the variety of the main agronomic traits needed to achieve as an indicator. For this reason, we used high-yield frequency distribution frequency analysis method to explore the grain-ear structure, the main agronomic traits and high-yield breeding ways of high-yielding wheat (500KG / 667 square meters). Materials and Methods We used the 1981-1990 winter wheat region in the region, the regional test in Hubei Province, Xiangfan City, a new test of wheat varieties (lines) and the Institute of Wheat
