Abstract
RESTREPO S, Edwin F; VALLEJO C, Franco A and LOBO A, Mario. Production of segregating populations with resistance to the fruit borer from crosses between tomato and wild accessions of Lycopersicon spp. Acta Agron. [online]. 2007, vol.56, n.1, pp.1-6. ISSN 0120-2812.
Interspecifics crosses between tomato plants L. esculentum and thirteen wild accessions of Lycopersicon spp. with resistance to the fruit borer were carried out. Six Hybrids population were produced which had low percentages of crossing efficiency and seed germination, and high amount of abnormal seeds. Seeds of four RC1 populations and four RC2 populations were obtained, which presented low percentages of backcrossing efficiency.
Equally seeds of three F2 populations and two F3 population were produced which were obtained from a low number of fruits in comparison with the high amount of isolated Inflorescences.
