Several important postharvest characteristics were evaluated in protoplast-derived somaclones after 2 consecutive growing seasons (1987-88). None of the somaclones had tuber yields significantly greater than the protoplast donor Crystal mother clone (MC); however, 8 of 37 clones had significantly lower yields. Of the 25 somaclones selected for Erwinia carotovora soft rot resistance testing, 1 clone demonstrated significantly elevated resistance to soft rot while 12 clones were significantly more susceptible relative to MC. Over half (20) of the 33 somaclones tested showed significant improvement in resistance to tuber bruising while only a single clone was more susceptible than MC. Based upon Agtron colour analysis, 5 somaclones showed significantly enhanced chip [crisp] colour when processed directly out of cold storage (6 deg C). Six clones had significantly improved chip colour after a reconditioning period (20 deg C). Four of the clones with significantly better cold processing characteristi

cs were also among the 6 with significantly enhanced processing quality after reconditioning. Some clones showed improvement in two or more characteristics. Clone 72-93 had significantly elevated resistance to both sof rot and tuber bruising while the bruise resistant clones 74-14, 71-41, 71-18 and 71-2 demonstrated significant improvement in both cold and reconditioned processing characteristics.
