Abstract:

The experiment was conducted to screen some maize varieties available in Bangladesh on the basis of their reproductive characteristics. Mean data were used to statistical analyze like analysis of variance, mean, range were calculated by using MSTATC software program. Significant variations among 50 maize genotypes in terms of all the yield contributing characters were found in this study. The lowest (24) days to 50% tasselling was found from the genotype 25KSS and VA-786, while the minimum (54) days to 50% silking was observed in the genotype PAC-984. The longest (21cm) cob was observed in the genotype VA-786, and the highest (17.07cm) cob diameter was recorded in the genotype GP-838.The highest (16.61) row per cob was recorded in the genotype NZ-001, and the highest (40.40) number of grains per row was recorded in the genotype PAC-399. The highest100grain weight (383.33g), was recorded in the genotype 25KSS, while the lowest (153.3g) was observed in the genotype of Uttaran-2. Statistically, significant variation was recorded for days to maturity in different maize genotypes. The highest (116) days to maturity were found in the genotype Elite, while the lowest days to maturity (107.3) were found in the genotype BHM-3. Grain yield (t ha-1) varied significantly in maize genotypes under the study. The average grain yield was recorded at around 6.14(t ha-1), and it ranged from 2.30 to 8.17. The highest grain yield (8.17 t ha-1) was recorded in genotype BHM-9, which was followed by PAC-984 (7.90t ha-1) and Pacific-98 (7.90t ha-1). Therefore, this experiment suggests that these three hybrids– namely,   BHM-9, PAC-984, and Pacific-98 have a high potential to produce more yield and are suitable for commercial cultivation in Bangladesh.
