RAPD markers are also identified for the distinctness of the new variety. Photosynthetic rate is also higher, and respiration rate is lower in “Vallabh Medha”. Fresh herbage and dry herbage yields harvested in “Vallabh Medha are 12331 kg ha-1 and 2113 kg ha-1 , respectively” comparing to 2050 and 392 kg ha-1 in the local variety. Active ingredients (asiaticoside, madecassic acid and Asiatic acid) are also present in higher quantity in “Vallabh Medha”.
