Abstract
The investigation was carried out to determine the genetic diversity, stability, and adaptability pattern among 40 genetic stocks of vetiver assembled from different states of India, with exotic collections from Indonesia, Reunion Island, Haiti, and Thailand. Samples were examined in terms of quantified degree of divergence using multivariate analysis. The range of D2 values from 30.16 to 16356.60 was indicative of high genetic diversity present in genetic stocks of vetiver. Further, stable genotypes for high oil yield were identified over the course of a year by using additive main effects and multiplicative interactions (AMMI) analysis. Based on the AMMI model, genotypes G-4, 5, 16, and 34 showed the widest adaptability/stability due to their ability to tolerate a wide range of environmental conditions.
