作者主要介绍罐藏番茄品种的主要加工性状之一——果实中可溶性固形物含量在一代杂种中的相对优势,并通过双对杂交中的半轮配法,估测该性状的一般配合力、特殊配合力以及遗传力。结果表明,可溶性固形物含量在一代杂种中的表现型是多种多样,但大多数杂交组合的F_1表现为超亲优势,该性状一般配合力和特殊配合力均达到极显著平准,估测其广义遗传力为81.04％,狭义遗传力为55.46％。果实中不同部位的可溶性固形物含量有差异。

The author mainly introduces the relative advantage of soluble solid content in the fruit of one of the main processing traits of canola tomato varieties, and through the half-round method of double-pair hybridization, the general combining ability of the trait, Special combining ability and heritability. The results showed that the soluble solid content in the first generation of hybrid phenotypes varied, but most of the hybrid combinations F_1 showed super-parental advantages, the general ability and special combining ability of the trait reached extremely significant level, estimated The general heritability of 81.04%, narrow heritability of 55.46%. There are differences in the content of soluble solids in different parts of fruit.
