DHWANI SHARMA, ARUNABH JOSHI, DEVENDRA JAIN and P.B. SINGH. 2017. Assessment of genetic diversity amongst some genotypes of groundnut using morphological markers. Green Farming Vol. 8 (5) : 1062-1066 ; September-October, 2017
Genetic diversity based on morphological markers amongst twenty four genotypes of A. hypogaea L. was investigated resulting in the following findings- ANOVA revealed significant mean square values that indicated substantial amount of genetic variability among the genotypes. The ANOVA of data revealed that mean squares due to genotypes were also significant for all the characters. On the basis of performance of genotypes per se viz., UG161, UG162, UG172, UG177, UG181 and UG184 showed superiority in yield attributes, therefore could be gainfully utilized in breeding programmes. Using Hierarchical Euclidean cluster analysis, the 24 genotypes could be grouped into five divergent clusters; Cluster IV was the largest containg 11 genotypes. Intra-cluster distances between the genotypes was maximum for cluster IV (54.04) while inter-cluster distance ranged from 7.78 between clusters IV and V to 13.96 between clusters I and II, indicating considerable amount of genetic variability.
