ABSTRACT
|
|
Fifteen exotic groundnut genotypes collected from ICRISAT along with a local check (Dhaka-1) were used to study their performance, genetic variability, heritability and genetic advance of yield and yield contributing characters. Significant variations were observed for all the characters in all the genotypes used in the experiment. Higher phenotypic coefficients of variations were observed for plant height, primary branches per plant, pods per plant, harvest index and pod yield plant 1. Characters like plant height, pods per plant, 100-pods weight, shelling percentage, harvest index and pod yield per plant showed high heritability. Considerable high genetic advances in percentage of mean were found for plant height, pods per plant, harvest index and pod yield per plant.
