Hybrid of Hardy Tamarillo’s (Cyphomandra corymbiflora x fragrans) - part 4

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).

On the left C. corymbifora, on the right the hybrid F1 (C. cormbiflora x fragrans)

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)

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

 

Hybrid of Hardy Tamarillo’s (Cyphomandra corymbiflora x fragrans) - part 3

On July 2019 I posted the photos of first flowers the hybrid of Hardy Tamarillo Cyphomandra corymbiflora (female parent) and male Guava Tamarillo C. fragrans = C. diploconos (male parent). Now the hybrid plants have young (immature yet) fruits. I am posting the photos of fruits and more photos of flowers. And on the and a few images of the parent plants. 

Hardy Tamarillo’s (Cyphomandra corymbiflora x fragrans) photos:

Immature hybrid fruit

The hybrid has saucer-shaped flowers (inetermediate to cup-shaped flowers of C. fragrans and star-shaped ones of C. corymbiflora). Young flowers are purple

Older flowers become almost white

The stem is characteristic maculated

The down part of trunk is not very swollen (resembles C. corybiflora one)

The lower leaves were lobed (similar to the ones of C. fragrans)

The upper leaves are no lobed. This is deciduous plant (as C. corybliflora, but lose the laeves later)

Young fruits (these fruits were created by hand pollination - backcrossing with C. corymbiflora)
