Selection of tomato lines and populations for fruit shape and resistance to tomato leafminer

ABSTRACT The market requirement regarding fruit type varies from region to region and it is necessary to produce cultivars with different patterns of fruit morphology. Therefore, the aim of this study was to select lines with resistance to tomato leafminer and different fruit shapes in order to meet the different market segments. Seventy-six lines and pre-selected populations were used for pest resistance together with four other susceptible controls (TOM-584, TOM-684, NC-123S, and Santa Clara) and two wild accessions (Solanum pennellii ‘LA 716’ and S. habrochaites var. glabratum ‘PI-127826’) considered resistant. The experiment consisted of tests of resistance to the tomato leafminer Tuta absoluta. The selection of lines was efficient, being obtained 33 lines or populations resistant to the tomato leafminer that comprise the market segments of the types of multilocular fruit, Santa Cruz, Saladette or Italian, as well as intermediate standards of fruits.
