Quality protein maize (QPM) commercialization can combat the food and nutritional insecurity that is common in some developing nations of the world. Evaluation of QPM hybrids under varying rainfed environments provide valuable evidence for the selection of the most productive genotypes for the target environment. The present study was conducted at three locations to assess the agronomic performance and the grain yield stability of 11 QPM and 2 commercial hybrids (checks) over two years. There were significant (p ≥ 0.01) differences among the environments in the expression of all measured traits while genotype as well as genotype × environment interaction also differed significantly for all the traits except for husk cover and Anthesis-silking interval. The tested QPM hybrids outperformed the local and reference checks by 17.28% and 29.47% respectively. The biplot explained 85.3% of the total variation in yield, with 65.4% attributed to principal component 1 and 19.9% to principal component 2. Three vertex hybrids, EWQH-25, EWQH-21 and Local Check, were identified as the most responsive in the environments within which they fall. Hybrid EWQH-21 produced the highest yield across all environments but was unstable. Therefore, hybrids EWQH-22, EWQH-9, and EWQH-13, with similar yield values and more stable performances were recognized as ideal across environments. Lapai 2017 (E2) proves to be both representative and discriminative, making it the ideal test environment for selecting hybrids with broad adaptability. The study concludes that EWQH-9, EWQH-13, and EWQH-22 be recommended for cultivation across the environments while EWQH-21 be recommended for the specific area of adaptation.

“…One hybrid EI-2145 x EI-2403 showed regression coefficient above unity (bi> 1) with higher mean values than population mean, While, hybrid EI-586-03 x EI-2416 exhibited regression coefficient less than unity (bi<1) with higher mean value than population mean, indicating hybrids performance were stable under favorable and unfavorable as moisture deficit environments for protein content, respectively. similar findings for starch content, oil content and protein content were reported by Dadeech and Joshi [6], Shanthi et al [7], Baudh Bharti et al [8] and Patel and Kathiria [9]. Further classification of genotype as per their suitability in different environment is shown in Table 4.…”

Sixty eight genotypes of maize (48 hybrids, 16 parents and 4 checks were evaluated under three different environments to test their stability. Variance due to genotypes, environments and genotype x environment interactions were found significant for oil content, starch content and protein content. Regression approach by Eberhart and Russel 1966 used to investigate the nature of G x E interaction and for identifying genotypes possessing general and specific adaption. None of the hybrids had stability for all quality traits. For Grain Starch content hybrid EI-1155-1 x EI-2416, for oil content hybrid EI-670-2 x EI-2403 and for Protein content hybrids EI-2187 x EI-2403, EI-536-3 x EI-2403, EI-2176 x EI-561-2,EI-2173 x EI561-7 had higher mean values, non significant deviation from regression and regression coefficient around unity (bi=1) indicating the stable performance in different environment and wider adaptability.

“…To avoid PEU, all essential amino acids must be present in the human diet. The normal endosperm maize commonly found in diets naturally has all essential amino acids, except lysine and tryptophan thus making it impossible to combat PEU without supplementation with other rich protein sources (Bharti et al, 2017). Despite the maize endosperm having other essential amino acids, lysine and tryptophan are equally essential in protein synthesis for tissue growth and also the conversion of tryptophan to niacin in the body reduces the incidence of pellagra (Babu and Prasanna, 2014;Motuma et al, 2015;Sharma et al, 2017).…”
