Influence of growth parameters on productivity potential in chilli (Capsicum annuum L.) genotypes

Abstract

Experiments were conducted for two years during kharif, 2018 and 2019 at University of Agricultural Sciences, Dharwad to identify potential chilli (Capsicum annuum L.) genotypes for higher productivity. Among fifty two genotypes, the genotypes DCA-33, DCA-37 and DCA-34 recorded maximum CGR (11.85, 8.84 and 8.33 g m-2 day-1), AGR (426.64, 318.18 and 299.93 g plant-1 day-1 x100), RGR (14.58, 14.48 and 13.63 g g-1 day-1 x1000) and NAR (15.20, 11.29 and 10.68 g dm-2 day-1) respectively during maximum peak vegetative growth stage between 60 and 90 DAP. Further, significant positive association of fruit yield with CGR (0.94**), AGR (0.94**), RGR (0.80**) and NAR (0.93**) at 60-90 DAP was observed. It is thus inferred that for developing ideotypes in chilli, higher CGR, higher AGR, higher RGR and higher NAR can be considered as an important physiological traits since, these parameters possess significant positive relationship with yield.
