通过对14个优良茄子品种及后代产量以及其构成因素的试验,结果表明茄子的果实数、平均果重和早熟性等产量构成性状不表现杂种优势;认为茄子产量杂种优势是亲本品种产量构成性状相互配合的结果,是基因累加作用的变量,是数量性状遗传现象,在上、下代的传递上是可以固定的。 The results of 14 elite eggplant varieties and their progenies and their components showed that the yield components of eggplant did not show heterosis, such as fruit number, average fruit weight and early maturity. It was considered that the heterosis of eggplant yield was the trait of the yield The result of mutual cooperation is the variable of gene accumulation, which is the genetic phenomenon of quantitative traits, which can be fixed in the transmission of upper and lower generations.
