Variation in Fruit and Seed Traits among Different Seed Sources of Calophyllum inophyllum L. Collected from Coastal Regions of Konkan, India

The present study was carried out in the College of Forestry, ACHF, Navsari Agricultural University during 2015 to understand the variation in fruit and seed traits among 15 seed sources of Calophyllum inophyllum collected from the coastal regions of Konkan (four locations from Maharashtra and one location from Karnataka). Fruits collected from each accession were evaluated for various fruit and seed traits viz. fruit length, fruit width, fruit weight, seed length, seed width, seed weight, seed volume, seed density, shell weight, kernel weight and shell to kernel ratio. It was observed that all the 15 seed sources showed a wide range of variation in fruit length (16.60 to 64.03 mm), fruit width (12.10 to 36.14 mm) and fruit weight (2.40 to 18.66 g) in collected seedlots. Fruits collected from CIMP1, CIMP4, CIMN1, CIMN2 and CIMN3 recorded to be bolder and bigger in size than other seed sources. Significant difference was observed among the seed sources for all seed traits, except seed width. Accession CIMP1 showed highest value for most of the seed traits, followed by CIMD3, CIMP4, CIMN1 and CIMN3 seed sources. Kernel weight ranged from 2.28 to 5.06 g, whereas shell weight varied between 1.13 and 2.88 g with an overall shell to kernel ratio ranging from 0.42 to 0.63. Considering growing condition, seeds collected from Maharashtra sources showed bigger and bolder seeds than Karnataka seed source.
