The experiment was conducted to estimate the genetic diversity in 14 different maize genotypes at
Agricultural Research Station Baffa, Mansehra Pakistan. The experiment was laid out in RCBD with three
replications. The results of analysis revealed that all the characters like days to 50% pollen shedding, days to
50% silking, plant height, ear height, 100 grain weight, harvest index and grain yield were significantly affected
due to various maize genotypes. The days to 50% pollen shedding ranged from 43.00 to 53.33 showed by
genotypes 24K42 and 2236, days to 50% silking from 46.67 to 55.67 days by genotypes 24K42 and 2234, plant
height from 139.00 to 230.70 cm by genotypes 25K56 and KT304, ear height from 68.33 to 104.33 cm by
genotypes 25K56 and 2236, 100 grain weight from 26.67 to 35.33 g by genotypes 24K42 and ND6876, harvest
index from 0.311 to 0.461 by genotypes CKD933 and 2235 and grain yield from 5.35 to 12.51 kg/plot by
genotypes 24K42 and ND6876, respectively. Evaluation revealed genotype ND6876 and genotype 2235 to be
the most promising ones and their adaptation to the agro ecological condition of this area can bring a substantial
increase in a maize grain yield.
Key words: Genetic diversity, genetic variations, maize yield parameters, seed yield, , ,
