The evaluation of early maize hybrids parental forms from alternative heterotic groups

Abstract

The process of creating corn hybrids includes the stages of systematization of lines inbred in germplasm groups, evaluation of parental forms, identification of the best performing pairs of germplasm groups with highly adaptive and reproductive heterosis in heterotic hybridization formulas. In this study 468 hybrids were included in 2021, 578 hybrids in 2022 from the first test stage for the agronomic value of them and their parental forms, represented by inbred lines and inter-related crosses AxA1.
