湖南省果梅资源中渗入了较多的杏、桃种质和少量的李种质,并且其中部分株系同时带有2～3个种的异种血缘。从变种间种质渗入的状况来看,所有试材均为有关变种间的过渡类型。聚类分析和特征对比的结果表明,这些资源可分为高、中、低度回交3个类型。其中,高度回交类的产量指数和单果重显著高于其余两类,而它们的苦味指数和花量指数却无显著差异。 There were more apricot and peach germplasm and a little plum germplasm infiltrated in Hunan plum resources, and some of the germplasm lines also had 2 or 3 species of heterologous blood. All germplasm infiltration from the morphological conditions, all the samples are related to the type of transition between varieties. Cluster analysis and feature comparison results show that these resources can be divided into high, medium and low backcross 3 types. Among them, the yield index and fruit weight of the highly backcrossed class were significantly higher than the other two groups, but their bitterness index and flower index had no significant difference.
