Abstract: | Summary Offspring were produced from a cross between two long-day-adaptedSolanum phureja clones which carried resistance to tuber soft rot (Erwinia carotovora subsp.atroseptica). In tests carried out on the produce of field-grown plants raised from tubers, over fifty per cent of the 173 offspring
were found to be highly resistant. Assessments were also carried out of tuber yield, mean tuber weight, tuber number, shape,
regularity, flesh colour, texture of the steamed flesh, fry colour, after-cooking blackening, sprout length after storage
and overall dormancy. There were statistically significant differences between clones for all characters (P<0.001).
Twelve of the clones were selected on the basis of high resistance, yield, tuber weight, regularity of shape and absence of
after-cooking blackening. The value of resistant long-day-adapted diploid material for commercial breeding is discussed. |
