Abstract

The investigational material consisted of fourteen genotypes of maize collected from Crop Science Institute, National Agriculture Research Center Islamabad. The study was conducted to investigate the genetic variability in different maize (Zea mays L.) genotypes for grain yield performance under local conditions of Rawalakot, Azad Jammu and Kashmir. The data was collected for some morpho-physiological traits like days to tasselling, days to silking, number of leaves plant-1, number of cobs plant-1, tassel branching, plant height (cm), ear height (cm), ear length (cm), ear girth (cm), number of kernel rows ear-1, number of kernels row-1, 100-grain weight (g) and grain yield (kg ha-1).  Statistically significant differences were found among all the maize genotypes for the characters under observation. Azam showed maximum number of cobs/plant, 100-grain weight, ear girth, kernel rows/ear and maximum grain yield. Genotype E-77 was a high yielding variety followed by Habib-1, Islamabad Gold and Margalla. These genotypes could be exploited in further breeding activities for the development of high yielding lines.
