I have Sal Gene,Hardy Chicago,and Sal Corleone,and all three cultivars are different,as to the shape of the fruits,and other minor differencies,-with Sal Corleone being much more different than the other 2.
Sal Corleone is later to ripe,larger fruits,the difference in flavor is much more pronunced,than in the case of ,Hardy Chicago verses Sal (gene).
Yet all three are very cold resistant cultivars,good to be grown outside ideal climate.
71GTO: I have a handfull of 2 years old,Hardy Chicago,but I have none of Sal (Gene strain),or Sal Corleone.
I did have a handfull of each but I sold them in November 2010.
I will make a few more layers,This Summer, from Sal Gene,and Sal Corleone.
I have no Bussiness to speak of,no emploee, just a propagation permit,for myself.
Also My Family members do not like gardening,except my 5 yrs old grandoughter.
