To gain an deep understanding of the genetic characteristics of domestic and foreign wheat germplasm and to screen superior resources for rational parental combinations, 490 wheat germplasm resources were used as experimental materials. Genetic diversity analysis, correlation analysis, clustering analysis, principal component analysis, subordinate function analysis and comprehensive evaluation were conducted on 22 major agronomic traits (including flag leaf length, plant height, number of fertile spikelets, thousand-kernel weight, kernels per spike, yield and et al.) and 7 quality traits (including grain crude protein content, wet gluten content, sedimentation value, volume weight and et al.). The results showed that the 490 wheat germplasm resources had abundant phenotypic diversity. The coefficient of variation (CV) for major agronomic traits ranged from 1.65% to 16.75%, being lowest for heading period and highest for kernels per spike. The genetic diversity index ranged from 1.74 to 2.07, with an average of 1.97, being highest for the number of fertile spikelets and lowest for growth period. The CV for grain quality traits ranged from 1.45% to 15.93%, being highest for sedimentation value and lowest for bulk weight. The genetic diversity index of grain quality traits ranged from 2.01 to 2.07, with an average of 2.04. Correlation analysis results indicated that: flag leaf length, plant height, number of fertile spikelets, kernels per spike, and thousand-kernel weight showed highly significant correlations with yield. Grain crude protein content, wet gluten content, and sedimentation value showed highly significantly positive pairwise correlations with extensibility. Principal component analysis (PCA) extracted three principal components, with a cumulative contribution rate of 64.64%. Among these: the first and second principal components mainly reflected information related to yield-related traits, and the first and third principal components mainly reflected information related to quality traits. Through cluster analysis, the 490 wheat germplasm resources were divided into five groups. Group Ⅰ had the highest average yield; Group Ⅱ had the highest average kernels per spike; Group Ⅳ had the shortest average growth period, and Group V exhibited significantly higher crude protein content, wet gluten content, sedimentation value, and extensibility compared to the other groups. Overall, Groups Ⅰ and Ⅳ demonstrated superior yield-related traits, while Group V showed outstanding quality-related traits. Comprehensive evaluation based on subordinative function analysis indicated that 22 wheat germplasms, including xf19200, Xikemai 3, Shannong 71, and Flanders exhibited better comprehensive traits. These can be selectively utilized based on the characteristics of their respective clusters in conjunction with the cluster analysis results.

为深入了解国内外小麦种质的遗传特征，筛选优异资源进行合理的亲本组配，以490份小麦种质资源为试验材料，对其旗叶长度、株高、可育小穗数、千粒重、产量等22个主要农艺性状，以及籽粒粗蛋白含量、湿面筋含量、沉降值、容重等7个品质性状进行遗传多样性分析及综合评价。结果表明，490份小麦种质资源表型多样性丰富。主要农艺性状的变异系数为1.65%~16.75%，抽穗期最低，穗粒数最高，遗传多样性指数为1.74~2.07，平均1.97；籽粒品质性状的变异系数为1.45%~15.93%，沉降值最高，容重最低，遗传多样性指数为2.01~2.07，平均2.04。经相关性分析，旗叶长度、株高、可育小穗数、穗粒数、千粒重与产量之间呈极显著相关；籽粒粗蛋白含量、湿面筋含量、沉降值与延展性之间两两互呈极显著正相关。通过主成分分析提取到3个主成分，累计贡献率为64.64%，其中第1、第2主成分主要反映产量相关性状信息，第1、第3主成分主要反映品质相关性状信息。通过聚类分析将490份小麦种质分为5个类群，类群Ⅰ平均产量最高，类群Ⅱ平均穗粒数最多，类群Ⅳ平均生育期最短，类群V粗蛋白含量、湿面筋含量、沉降值、延展性明显高于其他类群。综合来看，类群Ⅰ、Ⅳ产量性状较优异，类群V品质性状表现突出。基于隶属函数值分析的综合评价结果显示，xf19200、西科麦3号、山农71、Flanders等22份小麦种质的综合性状较好，可结合聚类分析所属类群的特征有选择地利用。
