Alike in other areas, greenhouse cultivation is getting special impetus in arid regions owing to providing
favourable micro-climate, besides protecting crops from various external crop limiting factors which causes
considerable losses to productivity. Cultivar selection is among the most critical aspect for successful
greenhouse cultivation. In order to select appropriate cultivar for peculiar arid conditions, the performance of
twenty indeterminate tomato hybrids were evaluated under greenhouse condition at Jodhpur during September
to April, 2016-17. The performance of hybrids was assessed for their growth, yield and quality characteristics.
Results obtained from the study reveal that the performance of tomato hybrids differ significantly for different
growth and yield parameters among them. Shoot (leaf + stem) biomass production showed wide variation
among the hybrids, ranging from 162g (IA05) to 225.7g (Avtar) per plant. Fruit yield also varied widely (2.36 kg
to 4.94 kg plant-1). Hybrid Myla (4.94 kg) was found superior in per plant fruit yield, followed by TR4343 (4.71kg) and TR4266 (4.65kg). Significant differences were also observed for fruit quality attributes such as pericarp thickness, total soluble solids, pH and EC in different hybrids. The character association analyses show that the yield per plant had significant positive correlation with average fruit weight (0.72), fruit diameter (0.50) and pericarp thickness (0.45). The highest fruit number was found in TR4266 (68.4), which had statistically similar per plant fruit yield with Myla. Whereas, the highest average fruit weight (166.8g), though lowest fruit number (40.3) was recorded in TR4293. The high mean values of the yield associated parameters in high-yielding hybrids Myla, TR4343, TR4266, TR4293 corroborates their production potential under geenhouse in arid regions.
