N2  - Tropical and subtropical maize germplasms are usually more stress tolerant and display greater genetic diversity than temperate germplasm. The new introgression germplasm, between tropical and subtropical germplasms and temperate germplasm, has displayed greater adaptability and stress tolerance. This will help to establish new heterotic patterns and develop new hybrids with higher yield and multiple tolerances. In order to achieve this, the genetic relationship between exotic tropical and subtropical maize germplasms and domestic temperate maize germplasm must be identified. Tropical populations such as Suwan1, Pop 21 (Tuxpeno ), Pop 32 (ETO), and Pop 28, and land races such as Antigua have high combining ability. Therefore, this study has analyzed the genetic relationship and combining ability of lines from these populations with temperate maize germplasm to assist in the creation of new heterotic patterns
