前言近年来育种工作在测验杂交组合,测定自交系配合力,特别是研究和比较品系的性能,是很重要很必要的。配合力是遗传性状,也是杂种一代研究的主要内容,目前玉米杂交工作很普遍,但是用双列法,不完全双列法检验一般配合力,特殊配合力及遗传力等,估算出数量性状有关遗传因素的效应还不太多。格列芬1956年利用双列杂交法进而估算出数量性状的一般配合力特
Introduction In recent years, breeding work in the test hybrid combinations, determination of inbreds combining ability, in particular, to study and compare the performance of the lines, it is very important and necessary. Combining ability is a genetic trait, but also the main content of the hybrid generation research. At present, the hybridization of maize is very common, but the quantitative traits are estimated by using double row method and incomplete double row method to test the general combining ability, special combining ability and heritability. The effect of genetic factors is not too much. Glicofen in 1956 using the double-line hybrid method and then estimate the number of general traits with traits
