Study of Stability analysis for yield and quality in Tomato (Solanum lycopersicum L.) over the seasons

Abstract

The present investigation was carried out in rabi, kharif and summer seasons at 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.
