Abstract
Genetic parameters like variability, heritability, and genetic advance influence the tomato yield. The present investigation comprises fourteen tomato genotypes augmented from different sources during summer season and were evaluated in randomized block design in three replications in field conditions. Fifteen different traits were evaluated. The aim of this experiment was to introduce traits which will help in improving not only the yield quantity but quality as well. High Phenotypic coefficient of variation (PCV) was observed for number of fruits per plant (NFP) (42.04), number of flowers per cluster (NFC) (32.80), pericarp thickness (PT) (30.72), total soluble sugar (21.34) and fruit yield per plot (FYPP) (20.90). For ascorbic acid (AA) (17.98), average fruit weight (AFW) (17.15), fruit length (FL) (14.18) and fruit yield per plant (FYP) (11.18) moderate PCV and for days to first harvest (DFH) (9.66), plant height (PH) (9.11) days to 50% flowering (DFL) (4.95), harvest duration (HD) (6.03) and number of locules (NL) (0.45) low PCV was observed. For NFP (42.01), NFC (32.70), PT (30.60), total sugars (TS) (26.23), total soluble solids (TSS) (21.32) high Genotypic coefficient of variation (GCV) and for AA (17.80), AFW (16.45), FL (12.82) and FYP (10.47) moderate GCV was noticed. Whereas low GCV was revealed in DFH (9.62), PH (9.07), DFL (4.14), HD (5.28) and NL (0.26). Highly significant variations were observed for all the traits studied. Genotypes shatabadi-314, DVRT-2, Himalaya, Punjab barkha bahar and arka abha performed the best.
