Summary, etc. Broadening the maize (Zea mays L.) genetic base is essential for improving grain yield. Suwan1, developed from a broad base of tropical germplasm in Th ailand, has recently been identifi ed as a heterotic group diff erent from Reid and non-Reid heterotic groups. Th e objectives of this study were (i) to evaluate the grain yield (GY) of crosses to see if there is value to utilizing Suwan1 as a heterotic group in maize breeding, and (ii) to investigate the general combining ability and specifi c combining ability to determine if Suwan1 shows good combining ability with Reid and non-Reid heterotic groups for GY. Th ree testers, one from each of the three heterotic groups, were crossed with 20 elite lines collected from across China. Eighteen lines improved via introgression of exotic germplasm and two lines improved via pedigree selection were crossed with TRL02 (non-Reid), YML46 (Suwan1), and TRL211 (Reid). Grain yield, ear length, ear diameter, kernel rows per ear, kernels per row, and 100-kernel weight of crosses and a check were evaluated at three locations. Th e results suggested that the Suwan1 ´ temperate crossing system was a very useful heterotic pattern. Suwan1 improved all fi ve yield components in crosses and demonstrated good combining ability for GY with Reid and non-Reid heterotic groups. We have also determined that the appropriate percentage of introgressed germplasm should be between 6.25 and 12.5%.
