摘    要:小麦种质资源是小麦育种的重要基础,小麦遗传多样性评价不仅有助于种质资源的搜集、管理和利用,也有利于核心种质的研究。为了合理利用小麦种质资源,降低组配小麦杂交组合的盲目性,选取73份国内外种质材料,在旱地条件种植,以株高、穗粒数、千粒重、有效穗数和产量为指标对其进行了聚类分析。结果表明,在雨养条件下各性状的变异系数大小为:产量>有效穗数>穗粒数>千粒重>株高;产量构成因素与产量的相关程度为:有效穗数>穗粒数>千粒重;供试材料可以分为六类,并对各类种质材料的特点及在育种中的应用作了评述。试验中综合表现较好的4个亲本材料为第Ⅵ组的18th FAWWON-IR-023、18th FAWWON-IR-111、18th FAWWON-IR-027和18th FAWWON-IR-169,可为选育抗旱优质丰产小麦新品种提供优异基因。

Abstract:

Wheat germ plasm resources are very important for breeding program. Genetic diversity study on wheat is beneficial to the collection, management and utilization of wheat genetic resources, and the establishment of core collection. In order to make efficient use of wheat germplasm resources and reduce blindness in combination selection of crosses, this study selected 73 cultivars in China to investigate the traits plant height, the grain number per spike, 1000-grain weight, the number of productive ear and grain yield, and all accessions were made clustering analysis based on these agricultural traits. The results showed that: the coefficient of variation among traits size under rain-fed cultivation: yield > spikes > grains per spike > 1000-grain weight > plant height; Yield components and yield related degree: spikes> grains per spike > 1000-grain weight. The cultivars could be divided into six groups. The character and application in breeding of per group were appreciated. Comprehensive trait of 18th FAWWON-IR-023 and 18th FAWWON-IR-111 and 18th FAWWON-IR-027 and 18th FAWWON-IR-169 are good in fourth group, its may be provide fine gene for breeding wheat variety with resistance drought and high quality and high yield.
