Abstract:

Cotton is a crop of prosperity having a profound influence on men and matter. The assessment of genetic variability is prerequisite for organization of breeding programmes in any crop. Experiment on estimation of genetic variability parameters in F2 population of cross a RHAP 24 × RHAP 15 was carried out at College of Agriculture, UAS Dharwad during kharif 2016-17. In the present investigation yield and yield attributes viz., number of monopodia per plant, number of sympodia per plant, number of bolls per plant, boll weight and seed cotton yield exhibited high PCV and GCV whereas, medium PCV and GCV was observed for plant height and maturity ratio. The fibre quality traits viz., upper half mean length, fibre uniformity ratio, fibre strength, strength to length ratio and fibre elongation percentage exhibited low PCV and GCV. In the present study plant height, boll weight and seed cotton yield per plant exhibited high broad sense heritability coupled with high genetic advance as per cent mean (GAM). Simple selection is effective for the traits exhibiting high heritability and high genetic advance.


Keywords: Heritability, Genetic variability, PCV, GCV and GAM
