福建杉木王种质资源的遗传多样性
Genetic diversity of germplasm resources of the king of Chinese fir in Fujian provenances
摘要
Abstract
On the basis of comprehensive survey, 44 samples of the king of Chinese fir germplasm in Fujian provenances were collected, and the population genetic diversity was detected by inter-simple sequence repeats ( ISSR) molecular markers. The results showed that the king of Chinese fir were mainly distributed in western, southern and northern of Fujian, but rarely distributed in eastern. Twenty-nine primers were amplified into 237 bands, 8.17 bands on average from a primer amplification. Two hundred and twelve bands were polymorphic, accounting for 89%. The population Nei′s genetic diversity index was 0. 342 8, and the Shannon information index was 0.502 6, which revealed a relatively high genetic diversity. Both of the unweighted pair-group method with arithmetic means ( UPGMA) clustering and genetic structure analysis showed the king of Chinese fir in Fujian provenances could be divided into 5 groups, which were comparatively agree with the geography distribution.关键词
