Potential Genetic Resources in Tomato Species: Clues from Observations in Native Habitats
All species can be readily grown for experimental purposes, and L. esculentum is widely cultivated under a wide range of environmental conditions.
Excellent sources of germ plasm now exist in the wild species as well as in modern and primitive cultivars of L. esculentum.
All of the wild species can be hybridized with L. esculentumn, albeit requiring special aids in certain combinations; fertility and viability of the hybrid generations permit the intended gene transfers. All species have 12 pairs of chromosomes, which are essentially homologous.
The cultivated species is well known genetically; its chromosomes have been mapped cytologically and genetically; it behaves as a basic diploid (27, 28).
