Abstract
ABSTRACT
The present study entitled “Combining ability analysis of fruit, seed yield and component traits in
sweet pepper (Capsicum annuum L. var. grossum)” was carried out under greenhouse conditions at the
Experimental Farm of the Department of Seed Science, Dr YS Parmar University of Horticulture and
Forestry, Nauni, Solan, Himachal Pradesh during the years 2017 and 2018. The experimental material for
the present study comprised of six parents and their fifteen crosses which were developed by crossing
these six diverse red sweet pepper lines in diallel design (excluding reciprocals). All the parents and their
hybrids along with the standard check (Bomby) were planted in Randomized Block Design for their
evaluation in kharif, 2018. The observations were recorded on eleven different traits, viz., days to first
flowering, fruit set (%), number of fruits per plant, fruit weight (g), fruit yield (kg per plant), days to first
ripe fruit harvesting, number of seeds per fruit, seed weight per fruit (g), seed yield per plant (g), thousand
seed weight (g) and percent seed recovery. The analysis of variance indicated highly significant
differences among the genotypes for all the traits studied. Experimental results revealed that two lines
viz., RSPUHF-7 and RSPUHF-2 were found to be superior for earliness. Whereas, the parents RSPUHF-4
and RSPUHF-2 were superior on the basis of mean performance and general combining ability studies for
fruit yield and seed component traits. Crosses RSPUHF-7 x RSPUHF-2 and RSPUHF-7 x RSPUHF-1
were found to be the best for earliness. Three cross combinations viz., RSPUHF-3 x RSPUHF-2,
RSPUHF-4 x RSPUHF-2 and RSPUHF-5 x RSPUHF-2 were found to be the best on the basis of mean
performance, heterosis studies and specific combining ability effects for fruit and seed yield traits. The
parents showing earliness, better yield and component traits and seed yield traits can be released as open
pollinated varieties for commercial cultivation. Similarly, the hybrids showing earliness, better yield and
component traits and seed yield attributes along with per se performance can be adopted for commercial
cultivation after their multilocation testing.
