Abstract
ABSTRACT
The present investigation entitled “Genetic evaluation of wild pomegranate (Punica granatum
L.) germplasm for various pomological traits”were carried out at the Kalaghat farm of Department of
Fruit Science, Dr. Y.S Parmer University of Horticulture and Forestry, Nauni, Solan, HP, during 2013-15.
The plant material was collected from four different district of Himachal Pradesh (Sirmour, Shimla, Solan
and Mandi) and planted at Kalaghat. This plant material has been flowering and fruiting for four to five
years. The experiment was laid out in FRBD. Evaluation study was carried out for various growth and
foliage characters, pollen viability and germinability, fruit physico-chemical characters, yield and insect
pest reactions among the germplasm. Among all the genotypes studied the plant material collected from
Shimla district had better vegetative growth (height, girth and spread) and maximum pollen germination
percentage (66.61 %) whereas Sirmour district plants performed best in terms of fruit characters viz.
weight (147.9 g), length (60.17 mm), diameter (66.00 mm), aril weight (65.68 g), peel and rag weight
(88.46 g), titratable acidity (6.84 %), yield (7.6 kg) and was most resistant to fruit spot disease. Thickest
rind among the germplasm was in Solan district. Pollen germination was found maximum (96.06 %) in
Mandi district’s plant. Genetic variability studiesrevealed that phenotypic coefficient of variation (PCV)
was higher than genotypic coefficient of variation (GCV) for all the traits studied. Higher heritability was
recorded for all the characters except stamen number, percentage of male flower. Genetic correlation
coefficient was higher than phenotypic correlation coefficient in most of the cases. Gross fruit yieldhad
positive and significant association with plant height, fruit weight, fruit length, fruit diameter, aril weight,
peel and rag weight, rind thickness, TSS, and total sugar. The path coefficient analysis revealed that
hermaphrodite flower had maximum positive and direct effect on yield and good amount of positive and
direct effect was also by intermediate flower, fruit weight and plant height.
