Abstract
ABSTRACT
Chilli (Capsicum annuum L.) is an integral part of Indian cuisine valued for its green
as well as dried ripe berries. Considering the economic importance of chilli in domestic
markets as well as in dried ripe berries, the present investigation entitled “Variability studies in
local chilli germplasm” was formulated and carried out at Experimental Farm of Vegetable
Science, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal
Pradesh, during the Kharif season, 2019. A total of twenty five genotypes including check
variety; DKC-8 were evaluated to ascertain the extent of variability, correlation and path
analysis for yield and other horticultural and biochemical traits along with estimation of
genetic divergence among the genotypes. The experiment was laid out in a Randomized
Complete Block Design with three replications. Analysis of variance showed presence of
significant differences among all the genotype studied. Six genotypes namely, LCC-5, LCC6,
LCC-7, LCC-13, LCC-16 and LCC-17 were found promising over the standard check
DKC-8 in terms of yield and other horticultural traits. High estimates of PCV and GCV
coupled with high heritability and high genetic gain was depicted for number of fruits per
plant, average fruit weight, green fruit yield per plant, ripe fruit yield per plant, dry fruit yield
per plant, dry yield as percentage of fresh ripe, ascorbic acid content, oleoresin content and
capsaicin content. Correlation together with path analysis studies revealed the importance of
number of fruits and average fruit weight on green fruit yield per plant whereas, ripe fruit
yield per plant and dry yield as percentage of fresh ripe parameters revealed their importance
on dry fruit yield per plant. Genetic divergence studies revealed that, the hybridization
between the genotypes belonging to clusters V and VI and clusters IV and V will be more
rewarding for getting superior progenies.
