英文摘要	The choice of testers is important for evaluating combining ability, and defining heterotic groups and patterns of maize germplasm effectively and accurately. This research was conducted on 108 testcrosses among 27 populations and four testers in order to (i) determine the effectiveness of testers to estimate general combining ability; (ii) select the best testers to determine heterotic groups and patterns. Seven trials were carried out in China. Each trial was arranged in alpha-lattice design (11 x 11) with three replications. Data for grain yield and agronomic traits were recorded. The variations among locations and genotypes were highly significant for all seven traits evaluated. The testers and populations showed significant variation for all seven traits evaluated. A high correlations between testers was observed for all traits. Testers HZ4 and Ye478 had large genetic distance and lowest correlation for grain yield when crossed with 27 populations, a finding that indicated these two lines as the best testers for classifying new germplasm into different heterotic groups and defining heterotic patterns in China.
