摘　要：

在干旱胁迫下, 本文测定了葡萄3个杂交组合5个亲本和126个F₁代植株的主蔓生长量、叶片相对含水量和叶绿素含量及细胞质膜透性, 综合评价了亲本及F1代的抗旱性, 并分析了F₁代抗旱性遗传倾向。结果表明, 亲本‘火州黑玉’为中抗型, ‘火州紫玉’、‘红宝石无核’和‘红地球’为低抗型, SP522为不抗型; 126株杂交后代中抗型单株6株, 低抗型单株117株, 不抗型单株3株; F₁代抗性呈现连续变异, 表现为数量遗传的特征, 亲本抗性强的组合获得抗旱杂交单株的几率大。

Abstract:

The study determined the degree of growth of the main vines, relative water content, chlorophyll content, and plasma membrane permeability in the leaves of the grape (Vitis vinfera) plants of 5 parents and 126 F₁ generations of 3 cross combinations, comprehensively evaluated their drought resistance, and analyzed the genetic tendency of the drought resistance of F₁ generation under drought stress. The results showed that grage ‘Huozhouheiyu’ was middle-resistance type; ‘Houzhouziyu’, ‘Ruby seedless’, and ‘Red globe’ were low-resistance type; SP522 was non-resistance type. There were 6 mid-resistance plants, 117 low-resistance plants, and 3 non-resistance plants in the 126 of F₁ generations. There was the characteristic of demonstrated continuous heteromorphosis of drought resistance and quantitative inheritance in F₁ generations, and there was more chance to get the panlts of resistance drought in the cross combinations with high-resistance parents.

Key words: grape (Vitis vinfera); drought resistance; genetic tendency
