Abstract: | Summary Using a modified embryo callus culture technique, hybrids between Lycopersicon esculentum and L. peruvianum were developed and their usefulness as bridge lines for facilitating interspecific gene transfer was evaluated. Four of these lines showed a high level of sexual compatibility with several other L. peruvianum var. typicum accessions, as well as with accessions of L. peruvianum var. humifusum and L. peruvianum var. glandulosum and L. esculentum. These bridge line x L. peruvianum hybrids could be crossed with L. esculentum to introgress genes from L. peruvianum into L. esculentum. |
