Variability Studies in Chilli (Capsicum annuum L.) with Reference to Yield Attributes

Field experiments were conducted at Regional Agricultural Research Station, Lam, Guntur, Andhra Pradesh during the rainy season 2004-2007, with ten chilli genotypes supplied by AICRP on vegetables (from different geographical sources). This was to study genetic variability, heritability and genetic...

High GCV and PCV were observed for ripe-chilli yield, dry-chilli yield, number of fruits per plant, number of seeds per fruit and fruit length indicating a higher magnitude of variability in these traits and, consequently, a greater scope for improvement through simple selection. Low GCV and PCV were recorded for plant height, plant spread and fruit girth suggesting a limited variability, for these traits. High heritability, coupled with high Genetic Advance as per cent mean, was observed for ripe-chilli yield, dry chilli yield, number of fruits per plant, number of seeds per fruit and fruit length, indicating the influence of additive genes.
