Genetic variability, heritability and genetic advance for growth, yield and quality components of Byadgi Dabbi ecotypes of chilli (Capsicum annuum L.)

In the present study, an attempt has been made to generate information on genetic variability using 55 Byadgi Dabbi ecotypes collected from different locations along with one local check. The variability, heritability and genetic advancement over the mean were performed for 16 selected parameters among the selected Byadgi ecotypes of chilli at Horticultural Research and Extension Station, Devihosur (Haveri). Higher phenotypic coefficient of variation is observed over genotypic coefficient of variation for all the traits studied, indicating the predominance of environment over the genetic parameters. Higher GCV and PCV were observed for Number of fruits per plant, stalk to fruit ratio, plant yield, capsaicin and oleoresin content of fruit. High heritability coupled with high GAM was observed for number of fruits per plant, stalk length, stalk to fruit ratio, plant yield, dry matter content, capsaicin content and oleoresin content. So, these traits imply the potential for crop improvement through selection.
