Hybrid Fruits of Camellia oleifera from Different Geographical Provenances and Seedling Growth Characteristics of F1 Generation
摘要
Abstract
In order to create new germplasm of Camellia oleifera,superior clones from two geographical prov-enances of "Cenruan" series and "Xianglin" series were hybridized as parents through artificial pollination. The main economic characteristics of hybrid fruits and the growth characteristics and heritability of F1 generation at seedling stage were studied. Results showed that the heritability of seedling height and ground diameter of the hybrid F1 generation was 0.821 5 and 0.828 5,respectively. It indicated that they were susceptible to genetic control and could be more stable. Compared with each trait,the two combinations of Cenruan 24×Xianglin 210 and Xianglin 210×Cenruan 2 had better performance,and the growth rates of seedlings were faster. The fruit setting rate and yield rate of Cenruan 24×Xianglin 210 were 82.50%and 52.5%,respectively,and the fresh seed rate was 50.45%. The fruit setting rate and yield rate of Xianglin 210×Cenruan 2 were 97.37%and 68.42%,respectively,and the single fruit weight and the single seed weight were the largest.关键词
