据《果树学报》2012年第2期《葡萄杂交后代对葡萄根瘤蚜抗性的遗传分析》(作者刘崇怀等)报道,利用室内离体根接种鉴定法,研究了6个杂交组合后代601个株系对葡萄根瘤蚜抗性的遗传特性,以期为葡萄抗根瘤蚜砧木育种提供理论依据。结果表明,亲本中SO4、5BB、1103P、河岸葡萄580、燕山葡萄0947、香槟尼1148抗根瘤蚜,而贝达和山葡萄对根瘤蚜敏感;6个杂交组合后代的葡萄根瘤蚜抗性分离呈连续性分布,表现出数量性状遗传的特性;在双亲组合过程中,美洲种群组成比例的多少,与其后代根瘤蚜抗性强弱呈正相关,表现为基因的累加作用;杂交后代葡萄根瘤蚜抗性的平
According to the “Fruit Tree Journal” 2012 the second period “hybrid grape offspring grape phylloxera genetic resistance analysis” (author Liu Chonghuai, etc.) reported that the use of indoor root inoculation identification method to study the six cross combinations of 601 offspring Department of grape phylloxera resistance genetic characteristics, in order to provide a theoretical basis for grape phylloxera rootstock breeding. The results showed that the parents were SO4, 5BB, 1103P, riparian grape 580, Yanshan grape 0947 and champagne 1148, but Beida and shan were sensitive to the phylloxera. The resistance of the phylogeny of the phylogeny of the six crosses was continuous Sexual distribution, showing the quantitative traits of genetic characteristics; parents in the process of composition, the proportion of the Americas population proportion of its resistance to the phylogeny of phylogeny was positively correlated, the performance of the cumulative effect of genes; hybrid grapevine phylloxera resistance level
