Studies on Genetic Diversity on Inflorescence Phenotypic Characteristics of Canarium album Germplasm Resource
摘要
Abstract
To understand the genetic diversity of inflorescence phenotypic characteristics of Canarium album (Loureiro) Raeuschel, the inflorescence characters of 90 germplasms of C. album were observed in Fuzhou Nursery of Chinese Olive Germplasm Resources of Agriculture Ministry. The results showed that the inflorescence characteristics, such as type, peduncle density, position and flower sex had abundant diversity. The variation coefficient of flower number was the largest, followed by the number of flower on peduncle, and that of flower bud diameter was the smallest. In addition, the male inflorescences had more diversities than female inflorescences. The flower bud diameter had significantly positive relation with petal length, and significantly negative relation with inflorescence length, peduncle number, flower number and flower number on peduncle. According to cluster analysis, the inflorescence type of C. album germplasms could be divided into 3 groups, there were distinct differences in most of male and female flower groups. Therefore, it was suggested that there were diversity and complexity in inflorescence phenotypic characteristics of C. album, and the important single trait would affect the overall phenotype.关键词
