The present investigation was carried out in rabi, kharif and summer seasonsat the Vegetable Research Station, Rajendranagar, Hyderabad. Six parents viz., LE-53, LE-62, LE-64, Arka Alok, Arka Meghali and Arka Vikas were crossed in diallel mating design. The resultant 30 F1’s were evaluated along with their parents and two standard checks (Lakshmi and US-618) for characters viz., fruit length (cm), fruit width (cm), average fruit weight (g), fruit yield per plant (kg), TSS (0Brix), lycopene (mg/ 100g) and shelf life (days). Present study revealed that, none of the hybrids have not stable for all traits. Among the all hybrids viz., Arka Vikas × Arka Meghali, Arka Meghali × LE-64, Arka Vikas × Arka Alok were identified as stable and best performing hybrids for fruit yield per plant with a significant higher mean hence, those are suitable for wider environments. Among all the hybrids, stability has been recorded by the Arka Alok × Arka Vikas and Arka Alok × LE-62 for fruit length, LE-62 × LE-53 and Arka Meghali × Arka Vikas for fruit width, Arka Vikas × LE-62 for lycopene, LE-53 × Arka Vikas and Arka Meghali × Arka Vikas for shelf life. The hybrid LE-62 × Arka Meghali followed by four hybrids and the hybrid Arka Meghali × LE-62 followed by six hybrids has been shown stability for the average fruit weight and TSS, respectively. Among all parents, Arka Meghali, LE-64 and LE-53 were recorded stable performance in wider environments for fruit width, TSS and lycopene, respectively.
