Genetic analysis and comprehensive evaluation of semi-lethal temperature in F1 progrny of intraspecific hybridization between'Dunkelfelder'and'Ecolly'
摘要
Abstract
To breed high-quality and cold-resistant wine grape varieties,the reciprocal cross progenies of Eurasian grape'Dunkelfelder'and'Ecolly'were used as experimental materials,the genetic analysis and comprehensive evaluation of winter bud mean high-temperature exotherm(mHTE)and mean low-temperature exotherm(mLTE)of 244 intraspecific Hybrid Progenies of'Dunkelfelder'and'Ecolly'were carried out in 2023,2024 and 2025 by using differential thermal analysis(DTA).The results showed that:1)The mHTE and mLTE values of winter buds in the intraspecific hybrids were continuously distributed,conforming to a normal or skewed normal distribution;The heritability of mHTE and mLTE values in the winter buds of the progenies of reciprocal crosses was more than 80％,and the generalized heritability ranged from 0.61 to 0.80.2)There was a positive correlation between the mHTE and mLTE values of winter buds,and the correlation coefficients in 2023,2024 and 2025 are 0.549 8,0.513 9 and 0.303 6,respectively.The judgment coefficients of the regression model differ greatly between years,the determination coefficients in 2023,2024 and 2025 are 0.302 3,0.264 1 and 0.092 1,respectively.3)According to the mHTE and mLTE values of winter buds for three consecutive years,among the 224 intraspecific hybrids of Vitis vinifera L.,2106007,2006008 and 2006014 of combination six,and 2110007 and 2010031 of combination ten can be regarded as the better cold-resistant strains.This study revealed that the cold resistance in V.vinifera belongs to quantitative trait inheritance,and a few superior strains of cold resistance can be created by intraspecific hybridization.关键词
