Abstract
Genetic variation in sixteen morphometric traits associated with thirty six accessions of Stevia rebaudiana was examined for selection of higher herb yielding accessions. ANOVA exhibited highly significant (p< 0.01) differences between thirteen traits. Correlation analysis resulted highest significant positive interaction between fresh branch weight-fresh stem weight (0.955**) and highest significant negative interaction between fresh stem weight- leaf/stem (dry weight wise) ratio (-0.484**).The most economic character fresh herb weight/plant exhibited high significant correlation between number of branches (0.818**). The path coefficient under study revealed that the highest direct contribution to total fresh herb weight/plant was made by number of branches (0.756).Indirect contribution of spread of plant via number of branches (0.595) for fresh herb weight/plant was large. Therefore, the traits like number of branches, fresh stem weight, dry weight of branch and dry herb weight/plant may be used as a better selection criterion for improvement of fresh herb weight/plant.
