Abstract:

The present experiment aimed to evaluate variability, heritability and genetic advance as per cent over mean for physiological and biochemical traits in twenty one thermo tolerant tomato genotypes. The experiment was conducted at the Experimental Farm, Division of Vegetable Science, Indian Agricultural Research Institute, New Delhi during spring–summer season (March-June) of the year 2014. Analysis of variance indicated highly significant mean sum of square due to treatment for all the traits and there was a sufficient amount of genetic variation in all the genotypes under study. Phenotypic coefficient of variation (PCV) was higher than the corresponding genotypic coefficient of variation (GCV) in most of the traits under the experiment. High PCV was observed in the characters viz., yield per plant (39.15), chlorophyll ‘b’ (24.40), chlorophyll ‘a’ (22.71), total chlorophyll (21.94) and lycopene content (22.46), whereas high GCV was recorded for yield per plant (38.79), chlorophyll ‘b’ (24.00), chlorophyll ‘a’ (22.26), total chlorophyll (20.95) and lycopene content (20.99). Yield per plant recorded maximum heritability (98.84%) followed by TSS (98%), proline (95%) and membrane stability index (MSI) (95%). High heritability coupled with high genetic advance was recorded in yield per plant, chlorophyll ‘b’, chlorophyll ‘a’ and total chlorophyll content. Similarly a joint consideration of heritability, GCV and genetic advance revealed high value for yield per plant, chlorophyll ‘b’, chlorophyll ‘a’ and total chlorophyll content. This showed that selection for these traits may be highly effective.
