Abstract
The effect of seed source, physiological age and desiccation date on sprout
growth, crop development, yield and fry colour following storage was
investigated over four seasons for the variety Maris Piper and in a parallel study
for the variety Rooster. Seed tubers were obtained from two areas of production,
Carlow and Donegal and received physiological ageing for either 0 or 200 day
degrees >4oC. Sprout growth, crop development, yield and fry colour following
storage was also compared over two seasons in the varieties Maris Piper, Rooster,
Fianna and Navan which had received physiological ageing for 200 day degrees
>4oC and grown at two sites.
Seed source produced an inconsistent effect on dormancy break, sprout growth,
emergence, tuber yield and reducing sugar concentration, but had no effect on
tuber sucrose concentration or chip fry colour following storage.
Physiological ageing advanced sprout growth, crop emergence, crop
establishment, usually improved tuber yield and dry matter content but had no
effect on chip fry colour following storage.
Delaying the desiccation date significantly increased yield in the grade >45 mm
in most experiments. Tuber sucrose concentration declined with delay in
desiccation date whereas fry colour tended to deteriorate with delay in desiccation
date.
When the varieties Maris Piper, Rooster, Navan and Fianna were planted at
Kildalton, Navan gave the highest yield of tubers >45 mm, while Rooster gave
the lightest fry colour following storage.
