The present study was carried out to investigate popping volume, yield and yield attributing traits in popcorn in order to generate information regarding the extent of genetic variability, heritability and genetic gain. The experiment was conducted with 20 hybrids with two checks during kharif, 2019 at Maize Research Centre, Rajendranagar, Hyderabad. Analysis of variance showed significantly superior for all the traits, indicated that considerable variability among the popcorn hybrids evaluated. Phenotypic Coefficient of Variation (PCV) was slightly higher than Genotypic Coefficient of Variation (GCV) for all the characters studied. Popping expansion ratio, grain yield per cob, number of kernels per row, cob length and ear height recorded higher estimates of genetic parameters indicating the predominance of additive gene action for expression of these traits and profuse scope for improvement of these traits through simple selection in pop corn.
