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.
