将参加1988年湖南省早熟玉米组区试的7个品种组合的有关数据进行相关分析和通径分析,认为玉米育种时,早熟品种的培育应注意选择长穗类型,而不能盲目追求大粒类型。
The correlation analysis and the path analysis of the data of 7 varieties combinations that participated in the precocious maize regional trial in 1988 in Hunan province suggest that the selection of long-ear type should be paid attention to when cultivating early-maturing varieties of maize, but not blindly pursuing the large-grain type.
