In cherry type tomato genotypes, Pusa Cherry No. 214 had maximum fruit length(cm), fruit girth(cm), weight of fruits per plant per plant(kg), total yield, and marketable yield (3.01 cm,2.91 cm, 4.08 kg, 485.33 q/ha, 446.11 q/ha, respectively) while in non-cherry tomato genotypes Arka Rakshak had maximum fruit length (cm), fruit girth (cm), weight of fruits per plant (kg), total yield and marketable yield (5.19cm, 4.69 cm, 3.08 kg, 366.64 q/ha, 334.68 q/ha). TSS was found maximum in TW4 (7.53 0B) and ascorbic acid content in Punjab Rood cherry (38.04mg/100g) in cherry tomato genotypes while Punjab Garud with maximum TSS and ascorbic acid content (6.470B and 11.96 mg/100g, respectively) had shown superior fruit quality in non-cherry tomato genotypes. Among the different cherry tomato genotypes, TF-1 had the lowest number of galls per plant, number of egg masses per root system and was found resistant with root-knot index of 2.00 while among the non-cherry tomato genotypes NT-8(Hisar Lalit) was found moderately resistant with root-knot index of 3.00. Therefore, it is concluded in the present study that among the screened tomato genotypes, TF-1 (cherry type, resistant) and NT-8 (non-cherry type, moderately resistant) can be grown as resistant cultivars or can be used as rootstocks for grafting in tomato for growing under nematode infested fields/polyhouse while Pusa Cherry No. 214 (cherry type tomato genotype) and Arka Rakshak ( non-cherry type tomato genotype) gave higher yield ( 485.33 q/ha and 366.64 q/ha, respectively) in comparison to other genotypes under field conditions in Haryana.EnglishThesis
