Abstract:

The research was conducted Kano University of Science and Technology teaching and research field and National Institute for Horticultural Research Bagauda both in Kano State, Nigeria. Population development was carried out in Wudil while evaluation of six parents, fifteen hybrids and four checks were carried out in both Wudil and Bagauda during 2022 raining season. The data collected were analysed using Statistical Tool for Agricultural Research System (STAR, 2018) for combined analysis across the two locations. The result significant difference between the entries for most traits measured days to 50% Flowering (24.4days), days to 50% silking (25.02days), Anthesis Silking Interval (3.55), Plant Height (450.87cm), Ear Height (372.41cm), Days to Maturity (26.72days), Ear Length (20.32cm), Moisture (5.96%), Crude Protein (3.28%), Crude fat (14.0%), Ether (8.50%) and Nitrogen free extract (5.15) indicating substantial variability among the entries for the affected traits.The means ranged from the highest entry P6 (57.33, 57.33, 95.67 and 9.73) for days to 50% flowering, for days to 50% Silking, days to maturity, crude protein, to the lowest entry TZEI 124, TZEI 125, P5, P1x P2, P4 X P5, (49.00, 51.33, 144.13 and 87.00) for days to 50% flowering, Plant height and days to maturity with a CV (4.67, 8.89 and 12.97) respectively. P1 shows highest mean for Ear length (20.33cm) and ear diameter (38.53cm) with CV of 11.1 and 76.65 respectively. TZEI 25 shows highest mean for percentage Ash (24.4%) followed by P1 x P2 (17.2%), P3 shows highest mean for moisture (18.63%) while check TZEI 124 has the lowest mean (12.90%) with CV of 2.98%. P6 shows highest mean for crude protein (97.3%) while P4 X P6 and P2 x P3 shows highest mean for Ether (50.6) and Nitrogen Free extract (87.13) respectively. The data indicate that seeds of the studied genotypes vary greatly in term of days to 50% flowering, days to 50% silking, anthesis silking interval, plant height, ear height, days to maturity, ear length, ash, crude protein, fats, crude fiber contents, ether and nitrogen free extract. The variability observed is both genetic and environmental which may influence the individual chemical composition. These results will be useful to know about the physicochemical properties of the studied maize genotypes and may guide us in designing strategies that maximize the utility of maize genotypes.
