Abstract:
Cotton (Gossypium hirsutum L.) belongs to Malvaceae family which is an often cross-pollinated crop. The present investigation was carried out using twenty-five genotypes for quantitative and qualitative traits of cotton to estimate the genetic variability present within genotypes. The material was evaluated in randomized block design with four replications during kharif, 2019 at Agronomy Instructional Farm, S. D. Agricultural University, Sardarkrushinagar. The differences between genotypes were significant for all the characters, which revealed considerable amount of variability for all the traits under study. The high genotypic and phenotypic coefficient of variation was observed for number of bolls per plant followed by number of monopodia per plant, lint yield per plant and seed cotton yield per plant suggesting the presence of considerable amount of variability. High heritability coupled with high genetic advance as per cent of mean were observed for number of sympodia per plant and number of bolls per plant, lint yield per plant and seed cotton yield per plant indicates the role of additive genes and less environmental influence on the characters and presence of adequate heritable variation. Thus it can be concluded that selection based on the traits like number of monopodia per plant, number of sympodia per plant, number of bolls per plant and lint yield per plant would be beneficial for further crop improvement.
