A study was conducted during the period of October 2013 to May 2014 at Pedstock Investments, Harare, Zimbabwe. The primary objective of the study was to assess growth and yield performance of new Israeli hybrid tomato (Solanum lycopersicum) varieties against Nemo-Netta variety under Zimbabwe conditions. The experimental was laid in a Randomized Complete Block Design with four treatments replicated four times. Treatments consisted of Israeli varieties (72061, 72205 and 79272) and Nemo-Netta as a control. Seedlings were transplanted at a spacing of 30cm x 1m in-row and interrow respectively and spacing between blocks was 50 cm. Data was analyzed using GenStat 14th edition and means were separated using Least Significant Difference (LSD) at 5% level of significance. There were no significant differences (P > 0.05) in stem thickness and distance between clusters among tomato varieties. There were significant differences (P < 0.05) in leaf area, days to maturity, shelf life and total fresh yield among varieties. Variety 79272 had the highest leaf area (131.2 m2) but was not significantly different from variety 72205 (127.1m2) whilst variety 72061 had the lowest leaf area (115.6m2) but was not significantly different from Nemonetta variety (116.3m2). Nemo-Netta took the shortest time to maturity (65.25 days) followed by variety 72061 (68.5 days) whilst variety 79272 took the longest time to maturity (90.25 days) followed by variety 72205 which was intermediate (70.25 days). Variety 72205 had the highest yield (153.6t/ha) followed by variety 79272 (134.6t/ha) which was not significantly different from Nemonetta variety (129.1t/ha). Variety 72061 produced the highest yield (116.5t/ha).  Variety 72205 had fruits with the highest shelf life (25.5 days) followed by Nemonetta variety (23.75 days). Variety 72061 had the shortest shelf life (20.25 days) followed by variety 79272 which was intermediate (21.25 days).  Results of this study show that Israeli tomato variety 72205 is better than Nemo-Netta variety in terms of yield and shelf life. Therefore farmers are recommended to grow 72205 and variety 79272 though further research is recommended in terms of diseases tolerance and other quality parameters
