Obtain and Chromosome Fragments Analysis of BC_1 Populations between Lycopersicon esculentum Mill. and L. peruvianum

In this paper,cultivated tomato Lycopersicon esculentum Mill. 1052 was used as female parent and wild tomato L. peruvianum LA3858 was used as male parent.One F1 hybrid was obtained by embryo rescuing method.The hybrid was backcrossed with Lycopersicon esculentum Mill. 1052 to generate BC1 progeny.And 6 single plants of backcross F1 species hybrids were obtained. Moreover,129 primers of CAPS,SSR and InDel on 12 chromosomes were used to analyze chromosome fragments of BC1 . The results showed that these 6 BC1 plants contained the whole genome of L. peruvianum LA3858.
