Genetic variability, heritability, correlation and path analysis in seenthil kodi (Tinospora cordifolia)

Abstract

India has a vast range of medicinal plants at its disposal. Tinospora cordifolia, often known as "Seenthil Kodi" , is a dioecious hanging shrub, proven to be a valuable botanical for herbal medicine, with an extensive array of bioactive components. The goal of the current research was to determine the ideal lines with high stem yield and also the assess genetic diversity, heritability, genetic advance and trait association in the crop. During 2021-2022, 48 genotypes were examined for 16 characters in CRBD. Higher PCV, GCV, heritability and GAM, according to studies on variability, indicate lesser environmental impact. According to correlation analysis, leaf fresh weight, leaf dry weight, stem fresh weight, stem dry weight, root fresh weight, root dry weight, whole plant fresh weight and whole plant dry weight were very significant and strongly connected with single plant yield. The path analysis revealed that the yield is directly and positively impacted by the stem yield. Thus, selection based on the fresh leaf weight and stem weight would aid in boosting whole plant weight.
