Abstract: The present investigation was carried out to evaluate 47 genotypes with 3 check varieties in respect of genetic variability, heritability and genetic advance for twelve yield contributing traits. Analysis of varience revealed, moderate to high level of genetic variability among different genotypes for all yield contributing triats. In general the value of phenotipic coefficient of variation (PCV) was higher than their respective genotypic coefficient of variation (GCV), but the extent was quite low. This indicates that there is very less environmental influence on the expression of characters. High value of GCV was recorded for the characters such as number of fruit per plant (53.15), unmarketable fruit yield per plant (46.93), average fruit weight (38.67), marketable fruit yield per plant (35.73), total fruit yield per plant (35.33). While low magnitude of coefficient of variability was exhibited by total soluble solid (6.19) and days to 50 per cent flowering (8.70).
