Abstract
This study included evaluation of five genotypes of maize in two locations (Bije and Hawiga), under three plant densities (A study was conducted to evaluate five genotypes of maize (El-Eiz, Behooth 106, Hybrid 2052, Hybrid 3001 and synthetic Ebia 5012) in two location (Beigie and Al-Hawiga) for its stability under three planting densities (47616, 57140 and 71428 plant / h) with spaces (20, 25 and 30 cm) between plants, and 70 cm between the rows, by using split plot design in RCBD system with three replications. A group of characters were studied (grain yield, weight of 300 grains, ear length, number of ear rows, ear diameter, ear height, plant height and leaf area. Combined analysis of variances showed significant differences for two locations at all studied characters expect number of ear rows, Hawiga location showed significant superior than Bije location in all studied characters except leaf area. The genotypes were showed significant differences in grain yield, ear height and plant height. The variety (106) showed higher stability in field characters, and the variety (5012) showed largest stability as compared with other genotypes. The results showed higher stability of two verities (El-Eiz and Behooth 106) in different locations and with different planting densities.
