Abstract

The present genetic variability studies in chilli (Capsicum annuum L.) was laid out at SKUAST, Chatha, Jammu in 2022. The experiment was conducted in Randomized Complete Block Design (RCBD) with three replications comprising 20 genotypes to study genetic variability, heritability, genetic advance and genetic advance as percent of mean among 17 different characters. Analysis of variance elucidated significant variations among the genotypes for all the characters studied. The GCV and PCV were high for number of fruits per plant (32.43% and 34.09%), yield per plant (32.18% and 33.73%), yield per hectare (32.18% and 33.73%), fruit weight (28.56% and 30.12%), number of seeds per fruit (26.61% and 28.68%) and capsaicin content (21.87% and 24.12%). High heritability was noticed for yield per plant (91.01%) and yield per hectare (91.01 %), number of fruits per plant (90.48%), fruit weight (89.88%), seed vigour index (88.59%), number of seeds per fruit (86.05%), capsaicin content (82.23%), number of primary branches per plant (81.86%), oleoresin content (81.70%), plant height (80.05%), fruit length (79.06%), fruit width (75.09%) and seed germination (60.92%). However, high genetic advance was obtained by yield per plant (388.16), followed by seed vigour index (188.32%), number of fruits per plant (121.00) and yield per hectare (99.38) and genetic advance as percent of mean was higher in case of number of fruits per plant (63.54%), yield per plant (63.25%), and yield per hectare (63.25%), fruit weight (55.77%), number of seeds per fruit (50.84%) and capsaicin content (40.86%), indicated that most of the traits studied were chiefly controlled by additive gene effect and thus selection may be rewarding.

Keywords

Chilli, Genetic variability, heritability, genetic advance, genetic advance as percent of mean

Conclusion

The highest genotypic and phenotypic coefficient of variation, genetic advance and genetic advance as percent or mean was recorded for yield per plant, yield per hectare number of fruits per plant, fruit weight, number of seeds per fruit, capsaicin content, seed vigour index, number of primary branches per plant, oleoresin content, fruit length, fruit width, and plant height. Therefore, showing the importance of these characters in the selection of a genotype for growth, yield and quality in chilli.
