在玉米杂种优势的利用中,如何组配一个强优势的组合是一个关键问题。长期的试验证明,亲本的自身表现不一定与后代的优势有直接的联系,有些亲本自身表观很好,但是用它组配的杂种一代优势并不强;有些亲本表现一般,但它组配的杂种一代的优势比较强,这就涉及到亲本的配合力问题。亲本配合力的高低对于组配强优势的杂交组合具有重要意义。我
In the utilization of maize heterosis, how to combine a strong combination is a key issue. Long-term experiments show that the parents ’own performance is not necessarily directly related to the descendants’ strengths. Some of the parents themselves are well-behaved, but the advantages of the hybrids using it are not strong. Some of the parents show a general performance, The advantages of the hybrid generation is relatively strong, which involves the issue of the combining ability of the parents. The level of parental combining ability is of great significance for the combination of strong heterosis crosses. I
