Citrus > Cold Hardy Citrus

F2 citrange winter hardiness trial

<< < (100/117) > >>

kumin:


 Poncirus showing late season flush being damaged by Winter lows of +2F and strong winds.

Undamaged 026 Segentrange grafted on Poncirus.



Undamaged 006 Segentrange sibling to 026.

There are several Segentrange selections that approach the hardiness of Poncirus quite closely.

Akebia:
Amazing work, thanks for the updates Kumin.  I would love to cross these hardy segentranges with my changsha and nagami and select for zone 7 adaptation.

Walt:
Akebia is right.  Working for zone 6 hardiness will have spinoffs for zone 7.

kumin:
My immediate plans are to cross the Conestoga Segentranges with Citrandarins containing Changsha parentage. 852 and progeny such as Bishop.
Additionally, to cross 5 Star Citrumelo with all of the above. 5 Star has survived here, but suffers dieback each Winter.
