First fruits of Citrumelo 5star x Morton cross
« on: October 30, 2018, 11:09:42 AM »
This year at the end of May the first of the hybrids that I made  in 2011 by pollination of 5* citrumelo flowers by Morton Citrange flowered for the first time:


 
Most of the  flowers were defective without pistils, but eventually three fruits were formed



Fruits began to change color at the end of September, one of them looks ripe now









It is approximately of the size of poncirus fruit, has a pleasant outside odor resembling orange with fruity overtone, albedo is thick with some faint bitter taste, juice is sour like a lemon with no bitterness, no internal oils, no perceptible poncirus aftertaste. By taste it is close  to unripe orange.
I measured a sugar content - it had 13.5 Brix (Spanish clementine in parallel showed only 11)

This  plant (11_03_24) is very resistant, probably more than both of its parents. It is in open ground without any protection since 2012, never was damaged by snow and freezing temperatures under conditions when both 5* and Morton showed some leaf damage. It requires a lot of iron supplement in  spring  to avoid deficiency, otherwise is very healthy 2 m high bush with small largely monofoliate leaves.
Could be an interesting step toward a  hardy citrus with sweet taste.

The plant and the fruit are really beautiful :D.
It takes another few years to evaluate the full potential of the fruit that looks promising.

Well done, Ilya. It will be interesting to see if the fruit quality changes (improves) over time.

Lovely. Morton and citrumelos are rather large fruits compared to other citranges. May this combination of the two produce larger fruit in the future?

I do not think so, evidently this guy decided to be of the size of its poncirus grandparents.
I still have its 5 brothers that survived out of initial three dozens. 
For me it is like a proof of  the concept, that it is possible to get rid of poncirus taste and to improve the hardiness with the respect of first generation hybrids.
It has also a tremendous advantage to ripen very early.
Best regards,

I will certainly follow this hybrid's development with great interest! Keep us updated.

This is very encouraging.
