Abstract:
The current research on" Morphological variations among Brahmi (Bacopa monnieri) germplasm accessions in A.P." was conducted at Dr. Y.S.R. Horticultural University, Horticultural Research Station, Venkataramannagudem, Andhra Pradesh. For 17 characteristics, genetic divergence was examined using Mahalanobis D² analysis on 22 Brahmi accessions. The accessions were classified into five clusters based on morphological characteristics. The greatest inter-cluster distance was found between clusters III and IV, indicating that there was a lot of diversity, and the greatest intra-cluster distance was found in cluster II, indicating that it has the greatest number of distinct accessions within the cluster. Cluster III has high mean values for plant height (54.42 cm), number of leaves (83.50), number of nodes per 15 cm stolon length (7.25), length of the stem (53.63 cm), number of branches (15.0), fresh weight of the leaves (375.00 gm^-2), dry weight of the leaves (93.50 gm^-2), dry weight of stolon+branches (153.75 gm^-2), dry weight of total biomass (247.25 gm^-2) but low mean values for leaf area (3.23 cm²), basal leaf area (411.79 mm²) As a result, these divergent and attractive genotypes may be exploited in future crop enhancement programmes of Brahmi.
