如何准确测定、评价玉米自交系的配合力,是玉米育种中的一个十分重要的问题。 玉米自交系的配合力有“一般”和“特殊”之分。所谓一般配合力,是指被测自交系与品种、综合种杂交后所表现出来的产量能力。品种或综合种是一个复杂的多基因群体,用一个自交系和它进行测验杂交的结果,相当于一个自交系分别和多个自交系测验杂交配合力总和的平均值。所谓特殊配合力,是指被测自交系和某自交系杂交后所表现出来的产量能力。
How to accurately determine and evaluate the combining ability of maize inbred lines is a very important issue in maize breeding. The combining ability of maize inbred lines has “general” and “special” points. The so-called general combining ability, refers to the tested inbred lines and varieties, hybrids after the hybrid output shown by the capacity. A variety or variety is a complex polygene population that is crossed with an inbred line and tested for its hybridization, which is the equivalent of a single inbred line with multiple inbred lines tested for the sum of the combining power. The so-called special combining ability refers to the yield capacity demonstrated by inbred lines and inbreds tested.
