为了解决玉米育种中产量试验的精确性低、一致性差等问题,并找到一个较好的组合筛选方法,本研究分析了玉米杂交种在不同环境下的产量表现能力,尝试将生产力、竞争力和补偿力进行分别估计,并研究了三者与其他性状之间的关系.结果表明竞争力与生产力呈负相关,同时竞争力与株高、雄穗分枝数、叶面积等性状正相关.这些结果将为玉米育种的组合选择和鉴定工作提供一个新的思路.

In order to resolve the problems of low accuracy and efficiency in the yield trials for maize breeding, and find a good method for maize hybrid identification, the appearance of maize yield in different growth environments in this article. The productivity, competitive ability and compensative ability were estimated, and the relationship between them and other traits were analyzed. It is showed that the competitive ability negatively related to productivity, and it positively related to some plant-type traits, such as plant height,tassel branch number and leaf area. These results will supply a new way for maize breeding.
