库尔勒香梨杂种实生苗性状分离初步研究
A Preliminary Study on the Trait Segregation of Hybrid Seedlings of Korla Fragrant Pear
摘要
Abstract
[Objective] The purpose of this article is to search the effective indicators of early selection for hybrid seedlings of Korla fragrant pears . [Method]The leaf characters such as leaf shape, leaf base, leaf margin,leaf vein and leaf color of 12 hybrid combinations of one - year Korla fragrant pear seedlings were observed, and the seeding height, diameter, leaf length, leaf width, petiole length and other related plant traits about combination of hybrid seedlings were measured. The separation variability and the extent of variation in plant traits of hybrid combinations were analyzed.[Result]The male parent such as Zaosu, Jinmi, Cuiguan, Suanli is growing stronger than other hybrid seedlings of 12 combinations, and the male parent named 81 - 15 - 10 hybrid combination for the significant variation of leaf shape is showing palmate notch shape ; plant traits displayed separate variability in one -year hybrid seedlings, and leaf size, seeding height were the largest in variation coefficient which can be used as the effective indicators of early selection for hybrid seedlings . [ Conclusion] The observed results of separate traits of one - year Korla fragrant pear hybrid seedlings could provide theoretical foundation to determine and select suitable seeding at earlier stage during the process of Korla fragrant pear hybrid breeding.关键词
