Genetic variation and correlation analysis of main characters in Malus sieversii resources
摘要
Abstract
[Objective] In order to interpret the genetic variation and correlation of characters in Malus sieversii, [Method] using 300 accessions of Malus sieversii as experimental material, 13 characters were investigated by analysis of correlation, principal component and path analyses. [Result] The results indicated that there was great genetic variation in 13 characters. The variation in fruit weight and Ca content was significant and there was great potential for further selection. Fruit weight was positively correlated to fruit length, fruit diameter, leaf length, leaf width and leafstalk length. Fruit diameter had the biggest direct promoting effect on fruit weight, and TSS content, fruit vertical length, shape index and leaf length could be used as assistant selection characters. [Conclusion] The studies suggested that there was great genetic variation in 13 characters, there was significant correlation or extremely significant correlation between each character, and there was great potential for further selection.关键词
