Uraria picta (Jacq.) Desv. ex DC. (Family Papilionaceae) is a critically endangered plant and one of the most important ingredients among the ten herbs used for ayurvedic formulation called as Dashmula. Considering the importance of the plant, the present investigation was undertaken to (i) evaluate and assess the genetic variability among the 23 accessions of U. picta based on various morpho-metric traits including rhoifolin content in root and aerial part and RAPD profiling (ii) estimate various statistical parameters such as broad sense heritability, genetic advance, direction and magnitude of correlation among the various morpho-metric traits as selection parameters and (iii) identification of potential accessions for their possible application in genetic improvement. The accession UP-18 was found to be most promising as the rhoifolin content in aerial part was 0.67 %, and in the root, it was 0.19 %. While the accessions UP-21 (1.01 %) followed by UP-19 (0.78 %), UP-11 (0.75 %) had highest rhoifolin content in aerial plant part. On the basis of growth and yield performance at CIMAP, Lucknow, UP-21, and UP-22 accessions performed well as compared to rest of the accessions. The RAPD profiling also identified accessions UP-23, UP-21, and UP-01 more genetically diverse which could be utilized in future breeding program to further broaden genetic variability and select desired plant type in Uraria picta.

Uraria picta（Jacq。）设计 前DC。（Papilionaceae科）是一种极度濒危的植物，是用于印度草药制剂的十种草药中最重要的成分之一，称为Dashmula。考虑到植物的重要性，本研究旨在（i）评估和评估美人鱼23种材料之间的遗传变异性根据根和空中部分的rhoifolin含量和RAPD分析等各种形态特征，估算各种统计参数，例如广义遗传力，遗传进展，各种形态特征之间的相关性方向和大小作为选择参数和（iii）鉴定潜在的材料，以便将其可能用于遗传改良。发现UP-18的登录号最有前景，因为其高空部分的rhoifolin含量为0.67％，而在根部为0.19％。UP-21（1.01％），其次是UP-19（0.78％），UP-11（0.75％）在空中植物部分具有最高的rhoifolin含量。根据CIMAP的生长和产量表现，勒克瑙，UP-21和UP-22的种质表现优于其余种质。Uraria picta。
