Will peruvianum cross with pimpinellifolium?
What characteristics does this species pass on to crosses?
There are some interesting Hawaiian varieties that trace back to some peruvianum parentage?

Will peruvianum cross with pimpinellifolium?
What characteristics does this species pass on to crosses?
Although the debate concerning Lycopersicon is still on, it is generally considered to consist of eight species. Dr. C.M. Rick, whom has spent a lifetime collecting and researching tomato genetics, has divided the species into two complexes (the L.esculentum complex and the L. peruvianum complex) based on their ability to cross with the common tomato Lycopersicon esculentum. The species can be classified differently when one considers geographic distribution, morphological features and compatability relations (see Taylor, 1986). We will consider the classification by Rick to examine the differing species.
The L.esculentum complex consists of six other species which are relatively easy to cross with the common tomato. All species in this group are diploid (2n = 2x = 24). Most (except L. hirsutum f. typicum and some L. pennellii) are self-compatible. They have yellow flowers and the stamens are joined to produce an anther cone. Fruit color varies depending on the species. Several members of this complex have provided sources of pest resistance in the cultivated tomato.
The L. peruvianum complex consists of two extremely diverse species which only hybridize with great difficulty. Both are diploid (2n = 2x = 24) and both occupy unique environments. These two species represent a wealth of characteristics which are potentially valuable to the cultivated forms. Their fruits are green and they are mostly self-incompatible. These species have been limited in their usefulness to cultivated forms due to various barriers present in sexual transfer (convential breeding). Often expensive techniques like embryo rescue are required to obtain plants from these crosses. However there are a few documented examples of crosses which have been utilized, for instance tobacco mosaic virus resistance and nematode resistance can be traced to sucessful sexual crosses between L. esculentum and L chilense.
