Abstract:

The experiment was conducted to screen the suitable maize hybrids available in Bangladesh on the basis of their vegetative characteristics. The mean and range were calculated by using MSTATC software program. Highly significant variations among 50 maize genotypes understudied. The range of cob height was recorded from 53 to 90 cm with a mean value of 74.29 cm. The highest cob height (90 cm) was recorded in genotype BM-5, and the lowest cob height (53 cm) was observed in the genotype PAC-999. Plant height varied significantly in different maize genotypes. It ranged from 156.67 cm to 298.90 cm, with a mean value of 210.34 cm. The lowest (156.67 cm) plant height was recorded in genotype Badsha, and the highest (238.90 cm) plant height was observed in genotype NZ-510. The average number of leaves per plant was recorded at 12.82, and it ranged from 10.53 to 14.63. The maximum (14.63) number of leaves per plant was recorded in the genotype BHM-6, and the minimum (10.53) number of leaves per plant was observed in maize genotype PAC-999. The average leaf length was recorded at 87.04, and it ranged from 65.33 to 102.10. The longest (102.10) leaf length was found in genotype BM-5, and the shortest (65.33) leaf length was observed in genotype Badsha. The average leaf breadth was recorded at around 8.81, and it ranged from 5.80 cm to 10.37 cm. The broadest (10.37 cm) leaf was recorded in genotype NZ-003, and the narrowest (5.80 cm) leaf was observed in the genotype of Badsha, which was followed by Kbd-222 (7.56 cm). The lowest plant height (156.67 cm) was recorded in genotype Badsha, and the maximum number of the leaf (14.63) per plant was recorded in the genotype BHM-6; these two hybrids can be cultivated as a commercial variety.
