本文以11个玉米自交系按双列式组配的55个单交组合为材料,在三个地点进行了两年试验,对九个经济性状的一般和特殊配合力及其与地点互作在年份间的差异性作了初步探讨。结果表明,各性状的一般配合力和绝大多数性状的特殊配合力方差分量在年份间无显著差异。各性状的一般和特殊配合力效应在年均间均呈高度正相关。多数性状的一般或特殊殊配合力与地点互作方差分量在年份间的差异不显著。据此认为,以一般和特殊配合力作为玉米自交系和杂交种的重要指标,在不同年份进行鉴定和选择的效果可能是基本一致的。
In this study, 11 maize inbred lines by double-rowed combination of 55 single cross combinations as materials, two-year trial in three locations, the nine economic traits of general and special combining ability and its interaction with the location The differences between the years made a preliminary discussion. The results showed that there was no significant difference between the general combining ability of all traits and the variance of special combining ability of most traits. The general and special combining ability of each trait showed a highly positive correlation in the annual average. The difference of the variance component of general or special affinities and location interaction of most traits in the year is not significant. Therefore, the general and special combining ability as an important indicator of maize inbred lines and hybrids in different years of identification and selection of the effect may be basically the same.
