Evaluación de especies silvestres de Lycopersicon sp, como fuente de resistencia a Scrobipalpula absoluta (Meyrick) y su intento de transferencia a Lycopersicon esculentum Mill

Thirty two (32) wild accessions of Lycopersicon sp. and one (1) cultivated accession of Lycopersicon esculentum Mill was evaluated to determinate the resistance to Scrobipulpa absoluta (Meyrick). The experiment was conducted with a complete random design and tour repetitions. Three (3) susceptibles cultivated accessions of L. esculentum (Chonto Mata Verde, Napoli and Chonto Santa Cruz Kada) was sowed to have natural infestation of S. absoluta. Demage intensity, number of buds demaged, number of leaves demaged and number of "blister" in the leaves was evaluated. AII evaluated accessions of L. hirsutum and L. peruvianum showed height resistance. 1406 and 1407 accessions of L. pimpinellifolium also was highly resistant. All evaluated accessions of L. esculentum var. ceraciforme and 1759 accession of L. esculentum was very susceptibles L. pimpinellifolium and L. hirsutum accessions have not problem to cross with L. esculentum var. tropic L. peruvianum accessions L. esculentum tropic do not produce hybrid seed; was necessary to cultivate unmaturity embryo, in vitro, using Murashige & Skoog medium but the plant regeneration was not possible.
