摘要
以国内外搜集的100份黄瓜资源为试材,对商品瓜的单瓜重、瓜长、瓜横径、瓜把长、中心腔横径、瓜心室数、可溶性固形物含量7个品质性状进行主成分和聚类分析,选出特征根累计贡献率为93.9087%的前4个主成分,在主成分分析的基础上,对100份黄瓜种质资源进行聚类分析,将其分为四大类群:第1类为短果型,共38份;第2类为短果优质型,共26份;第3类为长果型,共19份;第四类为多心室型,共17份。该研究为黄瓜优质新品种选育奠定了材料基础。
Taking 100 cucumber resources collected at home and abroad as test materials,the principal component and cluster analysis were carried out on the seven quality traits of commercial melon,including single melon weight,melon length,melon transverse diameter,melon handle length,central cavity transverse diameter,melon ventricular number and soluble solid content.The first four principal components with the cumulative contribution rate of characteristic roots of 93.9087%were selected on the basis of principal component analysis,100 cucumber germplasm resources were clustered and divided into four groups:the first group was short fruit type,a total of 38;the second type was short fruit high-quality type,with a total of 26 copies;the third type was long fruit type,a total of 19;the fourth category was multi ventricular type,a total of 17.It laid a material foundation for the breeding of new high-quality cucumber varieties.
