Genetic variability and correlation studies were made on the quantitative morphological features of six taxa of Brugmansia Pers. and five taxa of Datura L. from Kerala and Tamil Nadu. Pedicel length, acuminal peak length and fruit length showed higher values PCV and GCV reflecting a high degree of variability for these characters. ECV values were not high suggesting less environmental influence in the origin of such variations. All the flower and fruit characters studied showed a high percentage of heritability, above 85%. Maximum heritability (98%) was observed for fruit length, followed by 97% for corolla diameter and interacuminal peak length. Majority of the floral characters except calyx length, free filament length and fruit breadth showed higher values above 60%. Lamina length was found to be highly correlated genotypically to all the other foliar and floral characters studied at 1% level. The pedicel, calyx and corolla traits were highly correlated to most of the floral characters except fruit breadth
