Cambodia continues to rely on imports of vegetables including tomatoes to fill the local supply gap. A primary reason for the low domestic production of tomatoes is the lack of appropriate, high-yielding varieties with multiple desirable traits including long shelf life and good processing value. This study evaluated advanced lines of long-shelf-life and processing tomato from the AVRDC - The World Vegetable Center. The local commercial variety 'Mongal' served as the control in both trials. In the long-shelf-life tomato trial, CLN3940, CLN3947 and CLN3949 out-yielded the local control by 4-13 t ha-1. However, fruit shelf life of these lines was shorter than that of the control (23 days). Among processing lines, only CLN3125L-5X65 yielded comparably with the control; the rest had much lower yields. Total soluble solids of all entries were below 5 °Brix. Entries with high pulp yield (88-92%) for sauce processing and at the same time with relatively high yield of about 40 t ha-1 or higher included CLN3682C, CLN3552B and CLN3125L-5X65CLN3669a. These entries will be verified in advanced yield trials.
