ASSESSMENT OF GENETIC VARIABILITY AND ASSESSMENT OF GENOTYPE BASED ON MORPHOLOGICAL CHARACTERS OF TOMATO IN THE FIELD CONDITION

The present investigation entitled "Assessment of Genetic variability and assessment of genotype based on morphological characters of tomato in the field condition" was conducted in randomized block design with 30 genotypes of tomato in three replications.The objectives were to assess the relative performance, estimation of genetic parameters.The characters studied were morphological.The experiment materials comprised of 30 genotypes of tomato were collected from IIVR, Varanasi.The experiment was laid out at Vegetable Research Farm, ICAR-Indian Institute of Vegetable Research, Varanasi.The results of the study revealed that high GCV and PCV estimates were recorded fruit set (%) (41.36 and 41.39), pollen viability (28.56 and 28.63), fruit length (37.90 and 39.11), fruit width (41.45 and 42.46), yield/plant (74.57and 74.59) and number of fruits/plant (54.59 and 54.70).High heritability coupled with high genetic advance as per cent of mean indicates operation of additive gene action which was observed in traits plant height (cm) (98.79), number of primary branches/plant (75.51), days to first flowering (86.71), number of fruits/plant (99.61), flower drop (%) (99.98), fruit set (%) (99.84), pollen viability (99.49), fruit length (93.88), fruit width (95.32) and yield/plant (100.00).
