| 摘 要： | 以国家果树种质熊岳李杏圃中保存的405份中国李和杂种李为材料,依据32个主要形态性状和农艺性状的评价数据,对这些主要性状进行了遗传多样性、相关性和主成分分析.结果表明,中国李表现出丰富的遗传多样性;从字符型形态和农艺性状数据看,叶形、果形、果皮彩色和果肉色泽等性状均表现出较为丰富的多样性;从数值型形态和农艺性状数据看.各性状的变异系数为47.09%～14.85%;其中单果重的变异系数最大,为47.09%,其变幅为4.50～107.90g.其次是维生素C含量,变异系数为40.44%,变幅为0.80～14.70mg/100g;相关性分析得出,节间长度与一年生枝条长度和可溶性糖含量呈正相关,果实发育期与可溶性固形物和可溶性糖含量也呈正相关,而与可滴定酸和维生素C含量呈负相关.

| Abstract: | 405 accessions of Chinese plum resources and hybrids from National Germplasm Repository for Plums and Apricots,Xiongyue were taken as materials.The genetic diversity,correlation and principal components were analyzed,based on the evaluation of 32 morphological and agronomic traits of them.The results showed that the genetic diversity of Chinese plums distributed widely.The genetic diversity of the shape of leaf and fruit,the color of fruit skin and flesh behaved more various according to the character type ... |
