Abstract

Genetic variation in seedling characteristics was studied in 15 seedlots collected from selected trees representing different regions of Peninsular India and selected clones planted in CSO at Walayar (Kerala). Significant variations were obtained in a nested ANOVA in all the six characteristics, viz., seedling height, collar diameter, number of nodes, leaf length, leaf breadth and leaf length/breadth ratio measured at 3 months and 6 months of age in nursery. Genetic correlation among characters changed as the age advanced. Narrowsense heritability was higher for seedling height, collar diameter and number of nodes at 3 months than at 6 months and vice versa for leaf length, leaf breadth and leaf length/breadth ratio. Possibilities of using these seedling characteristics in measuring genetic distance between populations is also discussed in this paper.
