Evaluation of general and specific combining abilities of self-pollinated corn lines for yield and harvest moisture of grains

The objective of the study was to evaluate the general and specific combining abilities (GCA and SCA) of self-pollinated corn lines for yield and harvest moisture of grain. The research was conducted on the fields of the P.P. Lukyanenko National Grain Center in 2020–2022 due to the methodology of the All-Russian Research Institute of Corn for field experiments with corn. The evaluation was based on test-crosses using five testers. The results revealed significant differences in the combining ability of the lines, identifying the most promising lines for further use in breeding programs.
