Tomato field trial -- Evluation of germplasm selected in Agadir, Morocco at Sanarate, GT

    The main type of tomato grown in Morocco is for export to Europe and it is the Daniella type (round, indeterminate, firm, 110 g). The goal of the MERC-Moroccan project is to incorporate resistance to both begomoviruses and root knot nematodes into this type of tomato. Commercial hybrids with the appropriate growth habit and fruit type were crossed with the L. hirsutum resistant lines from Hebrew University of Jerusalem and L. peruvianum lines from Volcani Center. Resistant lines were selected in the open field in Morocco, where there are two monopartite begomoviruses, Tomato yellow leaf curl virus and Tomato yellow leaf curl Sardina virus. Several lines selected in Morocco were evaluate at Sanarate (high bipartite begomovirus pressure). The field conditions in Morocco are hot (sometimes near 45 C and dry) with moderate whitefly pressure. All plants selected had DSI < or = 2.
