Abstract
ABSTRACT
The present investigation entitled “Genetic evaluation of exotic germplasm of red cabbage
(Brassica oleracea var. capitata f. rubra)” was carried out at Vegetable Research Farm, Department
of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP)
during Rabi season, 2018-19. Twenty eight genotypes including check variety Kinner Red were
evaluated to ascertain extent of genetic variability, correlations, path analysis and genetic divergence.
The experiment was laid out in randomized block design with three replications. The observation
were recorded on days to fifty per cent marketable maturity, number of non-wrapper leaves, head
compactness (g/cm3), head color, head shape, gross and net head weight (g), equatorial and polar
diameter of head (cm), stalk length (cm), core length (cm), yield per plot (kg) and per hectare (q) and
vitamin C content (mg/ 100g). Analysis of variance showed highly significant differences among all
the genotypes for all the characters under study. Three genotypes namely EC 890012, EC 890013 and
EC 890011 gave higher yield and also performed better for quality and other horticultural traits than
Kinner Red. High heritability estimates coupled with high genetic advance were observed for days to
fifty per cent marketable maturity, stalk length and core length. Moderate to high heritability along
with moderate genetic advance was observed for head compactness, net and gross head weight, polar
and equatorial diameter of head, vitamin C content. Net head weight was positively associated with
vitamin C content, gross head weight, polar diameter of head, core and stalk length, number of nonwrapper
leaves, head compactness, days to fifty per cent marketable maturity, while it had negative
significant association with equatorial diameter of head at genotypic level. Among all the traits
studied, core length had maximum positive direct effect on net head weight followed by polar
diameter, gross head weight, number of non wrapper leaves, vitamin C content and days to fifty per
cent marketable maturity. Genetic divergence studies revealed that cluster II accommodated
maximum genotypes (13) and cluster I and IV being more diverse, hybridization between genotypes
will be more rewarding for getting superior hybrids and transgressive segregants
