I would like to share our experiment (last results) with crossing two rare Tamarillo species: Hardy tamarillo - Cyphomandra corymbiflora = Solanum corymbiflorum and Guava Tamarillo - C. fragrans = Solanum diploconos. The hybrid F1 created a few fruits. The hybrid connect the best features of its parents: is dioecious leaves, more frost hardy than C. fragrans and its fruits are better tasting than both parents fruits.
|  |  |  |  |  |  |  |  |  | I year 2019 we made successful back crossing with both parents (we had 
also success with crossing hybrid F1 with C. fragrans parent - 
combination which failed in experiment of prof. Lynn Bohs in 90' years).

| Over ripe fruits the hybrid F1(the fruits taste better than both parents - they are not astringet like C. corymbiflora, aromatic but not too acid, delicious) | 
 
Cyphomandra corymbiflora x fragrans x corymbiflora - BC1 hybrid
 
 
BC1 hybrid - C. corymbiflora x fragrans x fragrans (the combiation which we succed the first time in world at all) 
|  | 
| It has created flower buds but no flowers in first year from seeds
