The average F1 yields were found to be significantly correlated with the genetic diversity of the parental strains calculated from the zymogram patterns of five enzyme systems in a sample of eight strains and their diallelic crosses.Despite the relatively small number of loci (eight) studied, there is evidence that these codominant alleles are good markers for genetic heterogeneity that is a source of heterosis.
平均 F1 产量与从 8 个品系及其双列杂交的 5 种酶系统同工酶图谱模式计算得到的亲本品系遗传多样性呈显著相关。尽管研究的基因座数量相对较少（8 个），但有证据表明，这些共显性等位基因是遗传异质性的良好标记，而遗传异质性是杂种优势的来源。
