Hybrid of Hardy Tamarillo’s (Cyphomandra corymbiflora x fragrans) - current update

 We are pleased to have good news. Just yesterday an article was published about the new varieties of Tamarillo that we later breded. The entire work took many years and we are still continuing it. Tamarillo it is exotic fruit, the so-called "tree tomato". ...this that under the breeding of its new varieties there are working enthusiasts from Poland, what is at least strange ... it can be compared with breeding works to obtain new apple varieties in tropics. But as we read on FB - "even the creasiest passion, there is better than living by other people's affairs". ... we shyly hope that our Tamarillo varieties will enter the cultivation ... will it be so, time will tell ...If you are interested read our article:

Tamarillo 'Lynn' (Solanum 'Lynn')

Solanum  corymbiflorum x diploconos (F1)

Older flowers of Tamarillo 'Lynn' are almost pure white

The overripe fruits of Tamarillo 'Lynn'

Tamarillo 'Pinczow Springs' (Solanum 'Pinczow Springs')

(Solanum corymbiflorum x diploconos) x corymbiflorum (BC1)

The overripe fruits. This cultivar ripes very early and has good taste (without astringent aftertaste)

Tamarillo 'Iwona' (Solanum 'Iwona')

(Solanum corymbiflorum x diploconos) x diploconos (BC1)

This cultivar' flowers are very ornamental

 The works under breeding new cultivars will be continued.

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)

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

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)

The hybrid immature fruit
