Possible Mechanism Analysis for Heterosis of Hybrid Liriodendron Based on Seedling Growth and SSR Markers
摘要
Abstract
It is well known that there is an obvious heterosis occurred in interspecific hybrid of Liriodendron, however its genetic basis is not clear. In this paper, the heterosis of growth was estimated for 12 interspecific crossing combinations,and their heterozygosities and parentage genetic distances were also evaluated by using SSR markers. It was found that there were no significant correlations between heterosis and genetic distance and heterozygosity, which indicated there would be other factors relating to the heterosis of hybrid Liriodendron besides the genetic distance and heterozygosity.关键词
