摘要:

为筛选网纹甜瓜优质种质资源,本研究以32份不同来源的网纹甜瓜种质为材料,对9个农艺性状,采用基础统计分析、方差分析、相关分析、主成分分析及聚类分析等方法开展综合评价。结果表明,9个农艺性状的变异系数为5.72%~24.50%,其中小区产量的变异系数最大。相关分析显示,有23对性状间均达极显著(p0.01)相关。主成分分析将9个性状简化为3个主成分,累计方差贡献率达79.907%,分别代表果实产量与外观、生育期与网纹品质、果实内在品质与果形结构3个因子。聚类分析在欧式距离20处将32份种质划分为3个类群。综合得分范围为-1.37~1.05,其中19份种质得分呈正值,表现优于群体平均水平。排名前3位的优异种质为M3、M20和M9,可作为育种的核心亲本。

Abstract:

To screen high-quality netted muskmelon germplasm resources,32 netted muskmelon germplasm resources from different sources were used as materials,and comprehensive evaluation was conducted on 9 agronomic traits by adopting basic statistical analysis,analysis of variance,correlation analysis,principal component analysis and cluster analysis. The results showed that the coefficient of variation of the 9 agronomic traits ranged from 5.72% to 24.50%,among which the coefficient of variation of plot yield was the largest. Correlation analysis indicated that 23 pairs of traits showed highly significant(p0.01)correlation. Principal component analysis simplified the 9 traits into 3 principal components,with a cumulative variance contribution rate of 79.907%,which represented three factors of fruit yield and appearance,growth period and reticulation quality,and fruit intrinsic quality and fruit shape structure,respectively. Cluster analysis classified the 32 germplasm resources into 3 groups at the Euclidean distance of 20. The comprehensive scores ranged from -1.37 to 1.05,among which 19 germplasm resources had positive scores,performing better than the population average level. The top 3 excellent germplasm resources were M3,M20 and M9,which could be used as core parents for breeding.

Key words: netted muskmelon, germplasm resource, agronomic trait, comprehensive evaluation
