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 greenhouse in arid regions.Not Availabl

Not AvailableClimatic vagaries of arid zones make cultivation of annual crops risky and unsustainable. Horticultural sector proved beyond doubt its potentiality for gainful economy in such fragile ecosystems. Immense opportunity existed in arid zone for quality production of some of the most water economizing horticultural crops. In recent years arid and semi-arid regions witnessed a greater shift from traditional to commercial horticulture with constant government support and technical input of research and development institutions. Technologies developed on ber, pomegranate, date palm and other arid fruits by Central Arid Zone Research Institute, Jodhpur, Rajasthan showed significant impact on development of dry regions at national level. However, after near plateau for some time, horticultural scene in arid region was brightened up with introduction of newer options viz. commercial tissue culture techniques in date palm and pomegranate, protected cultivation of high value crops and new varieties and technologies in region's adapted species. However, expanding the scale of horticultural production is often hindered by lack of market access, technological awareness and abiotic stressesNot Availabl
