山葡萄不同代际间杂交群体抗寒性差异调查分析
Investigation and Analysis of Difference of Cold Resistance in Different Intergenerational Hybrid Populations of Vitis amurensis
摘要
Abstract
In this paper,14 hybrid populations from F1 to F3 generations of Vitis amurensis were used as materials from 2022 to 2023,and the genetic characteristics of cold resistance of Vitis amurensis were discussed by investigating the differences of cold resistance levels between and within different generations.The results showed that cold resistance decreased with the dilution of the blood of Vitis amurensis.The F1 generation had strong cold resistance,at least 87%of the offspring could overwinter without buried in soil,and didn't show maternal genetic characteristics.The cold resistance of F2 generation was significantly weakened.The cold resistance of reciprocal cross combination in F2 generation showed the characteristics of maternal inheritance,and more cold resistant offspring could be obtained by using cold resistant F1 generation as the mother.The cold resistance of F3 generation was weaker when F2 crossed with European subspecies than F2 generation,but the cold resistance of F3 generation was improved after crossing with American species or other parents containing cold resistance genes.关键词
