草莓果实若干数量性状的遗传分析研究

对8个草莓杂交组合F_1的181个株系的果实主要数量性状进行了测定和统计分析,研究和探讨了草莓果实主要数量性状的遗传倾向.结果表明:果实一级序果果重、二级序果果重、最大果重、可溶性固形物含量、果实硬度、维生素C含量均为多基因控制的数量性状,呈连续变异.F_1果实一级果重、二级果重、最大果重、果实可溶性固形物含量、维生素C含量都呈现出趋小变异,果实硬度呈现出增大的趋势,趋向变大.

Inheritance Analysis Research of Several Quantitive Characters of Strawberry Fruit

181 seedlings of 8 strawberry cross combinations were used to study the inheritance trend of main fruit quantitive characters. The result indicated that weight of the first grade fruit,weight of the second fruit, the biggest fruit weight, the soluble solid content, fruit firmness, vitamine C were quantitative characters with succession variance. As concerning F_1, the first grade fruit weight, the second grade fruit weight, the biggest fruit weight, the soluble solid content and Vc content trended mainly to be smaller, hut fruit firmness trended mainly to be bigger.
