Abstract

Field studies were carried out to evaluate the agronomic and yield traits of elite maize hybrids during 2019 and 2020 late cropping seasons with the aim to compare the agronomic and grain yield performance of the hybrids based on multiple traits and to assess the interrelationship among the traits measured. This study included three groups of elite maize hybrids and one open pollinated variety, totalling 126 maize genotypes. Alpha lattice design (RIBD) with three replications was used to lay out the treatments. Data on flowering, agronomy, grain yield, and yield components were recorded. Data collected were subjected to analysis of variance to test for genotypic variation. Genotype by trait analysis was done to assess relationships among traits, and identify which genotypes are outstanding for each trait. Among the 126 elites maize hybrids, EYTWH-3 (E1), SEEDCO1 (E2), M1124-12 (E3) and TZL COMP3 C4 had best performance based on multiple traits.  For early maturing groups, EHT, PLHT, KNO, EL and EG had high correlation with grain yield and was one of the most reliable traits for indirect selection for increased grain yield for early maturing maize hybrids for the late/ intermediate groups, the traits selected for increased grain yield were PLHT, EL, KNO and EG
