为筛选优异外源小麦种质材料,分析了94份引进小麦种质的有效穗数、穗粒数、千粒重等7个主要农艺性状的变异情况及它们间的相关性,并以7个主要农艺性状为指标,对94份小麦种质进行了聚类分析。结果表明,除了容重外,94份小麦材料的其他6个主要农艺性状均表现出较大的变异性,以不孕小穗数的变异系数(62.07%)最大;有效穗数、株高与产量的相关性达到极显著水平,有效穗数与千粒重极显著负相关;通过聚类分析,将供试材料分为9个类群,其中第Ⅱ类群的g-1020、g-1043、09A452等6份种质的产量三要素极为协调,产量水平与不孕小穗数也表现较好,可以用作配置杂交组合的亲本。
In order to screen excellent foreign germplasm materials, the variation of seven main agronomic traits of 94 introduced wheat germplasms, the number of spikelets per panicle and the thousand-kernel weight were analyzed and their correlations were also analyzed. Seven main agronomic traits Traits as indicators, the cluster analysis of 94 wheat germplasms. The results showed that in addition to the bulk density, the other six major agronomic traits of 94 wheat cultivars showed great variability, with the coefficient of variation (62.07%) of the spikelets of infertility being the largest; the effective panicle number, plant height and yield The correlation between the panicle number and the 1000-kernel weight was significantly and significantly negatively correlated. According to the cluster analysis, the tested materials were divided into 9 groups, of which 6 were g-1020, g-1043 and 09A452 The three elements of germplasm yield are extremely coordinated, the yield level and the number of spikelets also perform well, and can be used as the parents of the hybrids.
