番茄的单株产量由单株结果数和单果重所构成,在杂交育种中杂种后代某个产量性状表现良好的单株,由于受遗传和环境的影响,有的可能保持下来,有的则发生分离或变劣,这种情况给准确有效的选择带来一定的困难。为了增强选择的预见性,研究和分析杂种后代的遗传和变异,确定与选择有关 The yield per plant of tomato consists of the number of fruit per plant and the weight of fruit per plant. In hybrid breeding, some plants with good yield traits of the offspring of hybrids may or may not survive due to genetic and environmental factors Separation or deterioration, this situation to the exact and effective choice to bring some difficulties. In order to enhance the predictability of selection, the genetic and variation of hybrid offspring are studied and analyzed to determine the
