Abstract : Field and laboratory experiments were conducted in Bihar, India, in 2001-2002, to estimate the genetic variation in a collection of 20 mango cultivars based on yield per plant, fruit weight, total soluble solids (TSS) and acidity. Higher variation was observed for all characters. The cultivar Mallika recorded highest mean values for all the traits. Lowest yield per plant (9.88 kg) and fruit weight (102.26 g) was observed in the cultivar Neelam, which also showed medium TSS and high acidity. The magnitude of phenotypic coefficient of variation was higher in magnitude than the corresponding genotypic coefficient of variation. High heritability coupled with high genetic advance was observed for fruit weight suggesting additive gene action. The expected genetic advance was low for yield per plant, TSS and acidity.
