Selection of dwarf mango rootstocks through long range field trials is a laborious and time consuming process. hence investigations were carried out to screen the mango genotypes for their vigour at seedling stage. twelve polyembryonic and ten monoembryonic genotypes were screened for their vigour at nursery stage with different physiological parameters like stomatal density, phenolic contents, chlorophyll fractions, bark percentage and relative water content. among the different parameters phenolic contents, bark percentage and chlorophyll fractions were found to be very useful in predicting vigour of mango rootstocks at nursery stage.
