Abstract
ABSTRACT
The present study was confined to 19 mother trees of Diospyros montana Roxb. distributed in
Solan districts of Himachal Pradesh. Mother trees were selected from Nalagarh and Baddi area of
Solan district. Variation in fruit, seed and seedling traits were studied by collecting fruits of this
species in the month of Feb- March (2020). Repeatability coefficient was recorded maximum for
seed length. GCV, PCV and heritability was recorded maximum for germination percent. There was
large variation in tree phenotypic characters, fruit and seed traits. The maximum fruit weight, fruit
length, fruit width and germination percent was recorded for M5 and M7. Seedling parameters were
recorded maximum for M7. Great variation was recorded for wood parameters. Maximum specific
gravity was recorded for M7 and M2, fiber length and fiber diameter was recorded for M8 and M19 and
holocellulose content was maximum for M15. Maximum moisture content showed significant
correlation with specific gravity and alcohol- benzene extractives. Fiber length is correlated
with fiber diameter. Seventy three point thirty nine percent of total variation was explained by three
components for leaf, fruit and seed characters and 89.88% of variation was showed by five PCA for
wood parameters
