摘要: 为明确小麦(Triticum aestivum L.)产量与其他主要性状的相互关系,基于2021—2022年湖北省区域试验44个小麦品种的主要性状数据,通过灰色关联度分析不同小麦品种产量与其他农艺性状、品质性状和抗病性之间的相关性。结果表明,小麦产量与其他性状的关联度(r)由大到小依次为生育期(r=0.914 7)、容重(r=0.899 0)、株高(r=0.873 0)、千粒重(r=0.852 0)、穗粒数(r=0.827 2)、吸水率(r=0.821 8)、粗蛋白质含量(r=0.814 8)、湿面筋含量(r=0.768 3)、叶枯病发病率(r=0.522 2)、稳定时间(r=0.425 6)。这说明对产量影响最大的因素为生育期,其次为容重、株高;影响较小的因素为稳定时间和叶枯病病株率。在小麦新品种的选育和高产栽培实践时,主攻方向为容重高、生育期适中的品种,同时注重加强对株高的选择。

Abstract: In order to clarify the relationship between yield and the main traits of wheat (Triticum aestivum L.), 44 wheat varieties in Hubei Provincial regional test from 2021 to 2022 were used as materials, and the correlation between yield and other agronomic traits, quality traits and disease resistance of different wheat varieties was explored by grey correlation analysis. The results showed that the correlation degree (r) between the yield and the main traits was in the descending order of growth period (r = 0.914 7), the dry unit weight (r =0.899 0), plant height (r=0.873 0), thousands of grains (r=0.852 0), the number of ears (r= 0.827 2), water absorption (r=0.821 8), crown protein content (r=0.814 8), wet gluten content (r= 0.768 3), the leaf blight rate (r= 0.522 2) and stable time (r= 0.425 6). It showed that the factor that had the greatest impact on yield was growth period, followed by the dry unit weight and plant height; the factors with less impact on yeid were stable time and the leaf blight rate. In the breeding of new wheat varieties and the practice of high-yield cultivation, the main direction was the varieties with high dry unit weight and moderate growth period, and the selection of plant height was strengthened.
