Abstract
"Field investigation wth eight}""^ chilli accessions was undertaken to elicit
information on genetic variabilit>% character association and path analysis. at
Department of Olericulture, Kittur Rani Channamma College of Horticulture,
Arabhavi during 2001-2002.
Analysis of variance reveled highly significant (P=0.01) differences among
treatments for twenty two out of twent^^ eight growth and jaeld characters in
chilli. The values of genotj'pic and phenot5/pic co-efficient of variation were
moderate for the characters like fruit set, fruits per plant, early, late and total
fruit yield, fruit weight, fruit density, chlorophyll-a, chlorophyll-b, fresh and dr>'
red chilli >aeld, indicating the existence of little variability^ in the germplasm
evaluated.
High heritability coupled with high genetic advance over mean were
observed for plant height, plant spread, fruits per plant, late and total fruit
jaeld, ten fruit weight, fruit density, fresh and dry red chilli >aeld indicating
additive gene action for these traits. Therefore, selection for these traits would
be gainful.
Correlation studies revealed significant and positive association of yield
with tertiar^'^ branches, fruit length, fruit girth, fruit number, fruit set, early and
late fruit yield. The red chilli ^ield had highly significant and positive
association with plant height, teriiory branches and fresh red chilli jdeld,
suggesting possibility of simultaneous selection for these traits.
Path analysis revealed that the direct selection on early and late fruit
>aeld for total green chilli yield per plant, fresh red chilli ^deld and seed number
per fruit for dry chilli >deld would be gainful as they had direct effect.
Perse performance revealed that PMR-5, Byadgi Kaddi, 9646, Anagi and
9639 were found promising for green chilli >deld and PMR-5, 9639, 9646, VNa
and Anagi for drS^ chilli >deld. Pant Ci, PMR-5, Hissar Shakti and 9646 were also
found resistant against thrips, mites, aphids and fruit borer."
