Agronomic potential, pest resistance, and fruit quality in BC1F3 dwarf round tomato populations

Combining broad pest resistance, high yield, and nutritional quality of fruit in the same hybrid is a challenge for round tomato breeders. Thus, development dwarf line obtaining hybrids may be an excellent alternative achieving such objectives. The aim this study was to evaluate agronomic potential, quality, resistance BC1F3 populations. We evaluated 13 treatments 4 replications. Treatments consisted 10 populations originating from self-fertilization selected BC1F2, plus both parents (recurrent donor) commercial hybrid. traits were number fruit, mean weight, locules, shape, pulp thickness, longitudinal transverse diameter precocity index, soluble solids, β-carotene, lycopene, acylsugar content. data analyzed through means test. In general, there increase up 1035% average weight relation donor parent. addition, some had with 49% more lycopene compared hybrid, as well greater content leaves (273%). UFU-DW22 population stood out good higher content, which provides resistance. To continue research, second backcross suggested order obtain lines and, posteriorly, fruits compact plants, fruit.
