Abstract
An ideal hybrid of the plant breeder should have both high yield and stable. Thirteen white promising maize hybrids and two commercial hybrids were examined in trial B (first stage evaluation of new maize hybrid registration for grain yield in Egypt) in 2022 season at five Agricultural Research Stations (ARS). A randomized complete block design (RCBD) with four replicates was utilized. This study aimed to identify high yield, and stable hybrids based on different stability parameters. AMMI analysis exhibited that highly significant mean squares were obtained for; locations (L) and attributed by (49.96%) from total sum of squares, genotypes (G) had (13.28%) of the total sum of squares, and G×L interaction had (21.02%) of the total sum of squares. IPCA1 and IPCA2 were highly significant and recorded 58.91% and 27.29% of (G×L) sum of squares, representing 86.2% of the interaction variation for grain yield. Also, AMMI analysis showed that the promising hybrid G-6 had high grain yield and low values of ASV, IPCA1 and IPCA2, so this hybrid is better yield stability than rest hybrids. Meanwhile, according to six parameters (CV% bi, S2di, R2, W2i, Pi) and two non-parametric (Si(1) and Si(2)) as stability parameters, the promising hybrids; G-2, G-4 and G-6 had high yield and stable of most of studied stability parameters. This study recommends moving these hybrids to the following level of evaluation in Egypt hybrid registration program
