选出优良的玉米单交种,迅速应用于生产,是玉米育种的重点工作。按通常的方法选配组合,工作量大,见效慢。如能根据亲本自交系的外部性状,有预见性地组配组合,可大大提高育种效果。山东农学院、望奎县农业科研所等单位,对此曾有研究和报道。为了摸清在本区环境条件下玉米亲本自交系的外部性状与单交组合的优势的联系,为选配强优势单交种提供依据,我们于1981—1982年进行了此项研究。现将研究结果进
Select a good corn single cross, quickly applied to the production of maize breeding is the focus of work. According to the usual method of matching combinations, heavy workload, effective slow. If based on the external traits of the parental inbred lines, with predictive group combination, can greatly enhance the breeding effect. Shandong Agricultural College, Wangkui County Agricultural Research Institute and other units, which had research and reports. In order to find out the relationship between the external traits of maize parental inbred lines and the advantages of single cross combinations under the environmental conditions in this area, this study was conducted in 1981-1982 to provide basis for the selection of strong single crossbreds. Now the research results into
