Uraria picta Desv. (fam. Fabaceae) Sanskrit name ' Prishniparni' is an important constituent of the Ayurvedic drug Dashamoola. The herb is highly valued in traditional medicine for treating gonorrhoea, malaria, hypertension, mouth/throat sore, fever, wounds and to expel tapeworms. Increased industrial demand has threatened its population diversity, necessitating to score genetic diversity to realize genetic improvement to facilitate organized cultivation. Multivariate analysis (MVA) was performed to examine the genetic diversity of 23 accessions for the ten most valuable traits, that enabled grouping of various accessions into nine different clusters. While the inter-cluster divergence between clusters I and III and V and VIII varied from 30.72 to 575.76, the intra-cluster divergence ranged from 0.000 to 14.28 to 30.53. Cluster VIII had the highest average inter-cluster divergence (D2 = 395.80), followed by cluster IX (D2 = 273.81), while cluster II had the lowest average inter-cluster divergence (D2 = 112.08). Average D2 value for other clusters ranged from 131.45 to 162.86. The traits that contributed most towards genetic diversity were root rhoifolin content (22.30%), ranked 1st, followed by root weight (14.42%), ranked 2nd, aerial part weight (11.61%), ranked 3rd, rhoifolin content (11.59%), ranked 4th, and inflorescence length (8.99%), ranked 5th, respectively. Substantial genetic divergence was seen in the accession UP-5, followed by UP-11, UP-44, UP-50, and UP-51. Thus, it is possible that selecting them would result in a high genetic gain for root yield and quality traits. Root yield and rhoifolin content in root were the two traits that were major causes of genetic divergence. As a result, UP-5 is the accession selected for commercial exploitation, followed by UP-11, UP-44, UP-50, and UP-51. [ABSTRACT FROM AUTHOR] |
