Investigations were carried out to draw out information in 30 progenies of Ailanthus excelsa Roxb. genetic resources to elicit information on the Variability, Heritability and Genetic advance among the biometric and physiological attributes. The number of branches registered maximum PCV and GCV followed by volume index, plant height and basal diameter and chlorophyll ‘a’, chlorophyll ‘b’, chlorophyll a/b ratio and total chlorophyll content had recorded low phenotypic coefficient of variation and genotypic coefficient of variation. Plant height, basal diameter, Volume index, chlorophyll ‘a’, chlorophyll ‘b’, chlorophyll a/b ratio and total chlorophyll content had registered high heritability coupled with low, moderate and high genetic advance as percentage of mean. | Variability, heritability and genetic advance of Ailanthus excelsa
