摘要: 为了解燕麦茎秆的抗倒伏特性,本试验对98份国内外燕麦品种(系)的13个性状进行了描述性分析、相关性分析、聚类分析和主成分分析,发现98份燕麦品种(系)在不同性状上具有较大差异,具有丰富的变异,其中,茎基部第Ⅱ节间长度、茎基部第Ⅱ节间的抗折力及秆壁厚等3个性状的变异系数均大于40%;回归分析发现,茎粗与秆壁厚是抗倒伏评价的核心指标,综合贡献度达到29%;基于13个茎秆特性指标的聚类分析可将98份燕麦品种(系)划分为 3 个类群,其中,第Ⅰ类和第Ⅲ类群为抗倒伏组,第Ⅱ类群为易倒伏组;通过田间观察和主成分综合评判,筛选出‘ZY25’(S41),‘XZ06005’(S90),‘坝莜13号’(S22),‘远杂1号’(S5),‘WDY1’(S96),‘PX0412’(S85),‘X2060388’(S92),‘白燕20号’(S17)等材料为抗倒伏优异种质,在抗倒伏育种优先选择。

Abstract: In order to understand the lodging resistance characteristics of oat stems, descriptive analysis, correlation analysis, cluster analysis and principal component analysis were conducted on 13 traits of 98 domestic and foreign oat varieties (lines) in this experiment. The results showed that 98 oat varieties (lines) had significant differences in different traits and relatively rich variations. Among them, the coefficients of variation of three traits, namely the length of the second internode at the base of the stem, the flexural resistance of the second internode at the base of the stem, and the thickness of the stem wall, were all greater than 40%. Regression analysis revealed that stem thickness and stem wall thickness were the core indicators for evaluating lodging resistance, with a comprehensive contribution of 29%. Based on the cluster analysis of 13 stem characteristic indicators, 98 oat varieties (lines) could be divided into 3 groups. Among them, the first and third groups were the anti-lodging group, and the second group was the easy-to-lodging group.Through field observation and comprehensive evaluation of principal components, materials such as ZY25, XZ06005, Bayou No.13, Yuanza No1, WDY1, PX0412, X2060388 and Baiyan No.20 were screened out as excellent anti-lodging germplasms. It is preferred in anti-lodging breeding.
