本文分析了番茄品种间一代杂种在早熟性、产量等主要经济特性以及这些特性的构成性状上的遗传表现,肯定了番茄一代杂种优势的利用价值。杂种在早期产量上平均较亲本增产30.85％,在总产量上增加12.72％,同时抗性增强。亲本的选配对杂种优势的表现有很大关系。杂种在产量上存在优势,但是在产量的构成性状上不一定存在优势,因此认为杂种优势的产生是亲本优良性状组合的结果。在选配亲本组合时,要选择早熟或丰产的,并且有最好的配合效果的为亲本。
In this paper, we analyzed the main economic traits such as prematurity, yield and other genetic traits of tomato hybrids and confirmed the utilization value of the hybrid heterosis of tomato. Hybrids in the early yield increased by an average of 30.85% than the parent, an increase of 12.72% in total output, while increased resistance. The matching of parents has a great relationship to the performance of heterosis. Hybrids have advantages in yield, but they do not necessarily have advantages in the traits of yield. Therefore, the generation of heterosis is considered to be the result of the combination of superior traits in parents. In the matching parent combination, to choose precocious or high yield, and the best with the effect of the parent.
