โœฆ Synopsis

The use of gamma irradiation to control sprouting and increase the length of storage time of potatoes has been proposed as an alternative to cold storage or the use of chemical sprout suppressants. Indeed, it is applied on a commercial-scale to potatoes in Japan. This research reports on the e โ€ ects of di โ€ erent levels of gamma irradiation on seven potato cultivars in relation to chlorophyll and glycoalkaloid synthesis on subsequent exposure to light after a period of storage. There were signiรcant genotype di โ€ erences between cultivars in their response to gamma irradiation, with some cultivars exhibiting dramatically reduced levels of glycoalkaloid synthesis compared with others. Also, cultivars responded di โ€ erently to variable irradiation levels. The implications of the results are discussed in relation to public health concerns and selection within potato breeding programmes.

Potato tubers of four varieties (Brodick, King Edward, Pentland Dell and Record) were stored under commercial conditions and exposed to light for up to 10 days after 0, 10, 20 and 30 weeks. These were analysed for photosynthetic pigment and glycoalkaloid content. There was no signiยฎcant alteration i
