Abstract
ABSTRACT
The secondary data for the present study “ Statistical investigation on yield attributing
characteristics of Punica granatum” were collected from the Department of “ Tree Improvement
and Genetic Resources”, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni ,
Solan, Himachal Pradesh.Data on different morphological and seedling characters, namely tree height
(m), tree diameter (cm), crown spread E-W (m), crown spread N-S (m), fruit weight (g), leaf
length(cm), internodal length(cm), collar diameter (mm), number of branches per plant and leaf
petiole (cm) were considered from five different districts. Two locations were considered from each
district viz; Narag and Neripul from Sirmour district, Waknaghat and Sadhupul from Solan district,
Sundernagar and Rewalsar from Mandi district, Mohal and Banjar from Kullu district, Basantpur and
Sunni from Shimla district. Different morphological and seedling characteristics of ten seed sources
were evaluated by contrast analysis, which varied significantly among the different districts and
within the districts. It is concluded that tree diameter (cm), crown spread E-W (m) and crown spread
N-S (m) was found maximum in Solan district and minimum in Shimla district, whereas collar
diameter (mm), leaf length (cm) and number of branches per plant was found maximum in Mandi
district and Minimum in Shimla district. Tree height (m) and Leaf petiole (cm) was recorded
maximum in Kullu and Sirmour district and minimum in Shimla district, whereas fruit weight (g) and
internodal length (cm) was found maximum in Mandi district and minimum in Solan and Sirmour
district. Cluster analysis was performed and the seed sources were grouped into three clusters.
Discriminant analysis was carried out to categorise the seed sources into high and low yielders. Tree
diameter, Tree height and crown spread E-W are the most important characters that discriminate the
two groups. Six seed sources from Mandi, Kullu and Shimla district were high yielder whereas other
four seed sources were lowyielder. Three principal components (PCS) were extracted out of ten which
explained 34.675, 23.002, and 11.587 per cent of the total variation respectively amounting to 69.26
per cent of total variation.
