摘　　要：为了在小麦品质育种中合理利用品种资源,以株高、穗长、韧度、有效分蘖、结实小穗数、不孕小穗数、单穗籽粒数和单穗粒重为指标,对引进的17份冬小麦和63份春小麦品种(系)进行系统聚类分析表明,参试小麦材料分为3类,其中24份品种综合表现较好,它们的株高和主茎穗长平均值较大,且植株的韧度较大,分蘖相对较多,不孕小穗数较少,单穗籽粒数和粒重都较高;5份品种(系)的株高很低,植株韧度较小,有效分蘖少,结实小穗数少,单穗粒重较低,不宜选作杂交亲本。In order to use resources rationally in wheat quality breeding, system clustering analysis was conducted based on plant height, spike length, toughness, available tillers, seeding spikelet number, the number of futile spikelets per ear, kernel number per spike, kernel weight per spike in 17 winter wheat and 63 spring wheat cuhivars （lines）. It showed that all the lines were divided into three classes, 24 of them were better than others in synthenic traits. Plant height, main stem and the average of spike length are larger, plant toughness, kernel number per spike, kernel weight per spike, and the number of tillers were relatively larger than that in other lines, but the number of futile spikelets per ear was less than others. Five cultivars was lower than the others in plant height, plant toughness, available tillers number, seeding spikelet number and kernel weight per spike. They were not suitable for the hybrid parent in the cross breeding.
