Under the climate change scenario, protected cultivation may possibly provide ample scope for ‘off’ season production of high value vegetable crops like tomato (Solanum lycopersicum Mill.). The performance of four tomato cultivars (Heemsohna, NS-1218, KSP-1113 and Heemshikhar) in terms of yield and quality parameters under polyhouse (greenhouse) condition was evaluated. The lycopene content and three pectin fractions (water soluble, ammonium oxalate soluble and alkali soluble) of fruits were analyzed by spectrophotometric methods. The total fruit weight/plant varied from 4.16 kg (KSP-1113) to 18.04 kg (Heemsohna). The fruit number per plant varied from 114.2-263.0 and individual fruit weight ranged from 18.47-121.12 g. Heemsohna registered higher yield along with maximum marketable shelf life (13 days) as compared to other cultivars. Lycopene content ranged from 2.63 to 5.81 mg/100 g FW with maximum lycopene in KSP-1113. Though alcohol insoluble solid was maximum (2.36%) in KSP-1113, water soluble and ammonium oxalate soluble pectin fractions were maximum in Heemsohna (9.02 and 15.76 g/100 g AIS, respectively) and alkali soluble pectin was maximum in NS-1218 (4.72 g/100 g AIS). Heemsohna can be grown in polyhouse for higher yield and overall quality characters and KSP-1113 (cherry tomato) can be grown particularly for higher lycopene content under protected condition in subtropics.
