Processing qualities of different potato strains
4 varieties were bred, Annabelle, Milva, Salome and Gullauga. The cultivation took place on Korpa in typical peatlands and Annabelle and Gullauga had a better harvest than the other varieties, in addition to which Gullauga had the highest dry matter content. The varieties came out very differently from the production episode that was carried out at Sölufélagið. Salóme's utilization was by far the best, Gullauga had deep eyes that reduced the utilization, part of Milva was damaged and was sorted out and Önnubelle's shape prevented good utilization. In the consumer survey, participants identified smaller differences between potato varieties than they did in the last survey, and the participants' tastes were different. In general, the Gullauga potatoes came out best in the consumer survey, although the differences between varieties were only significant in appearance. All varieties still appear to be processable after storage at 5.7 ° C for up to 200 days after recording, although some varieties have begun to germinate, albeit to varying degrees. In terms of processing, Milva, Salome and Gullauga all came out well in terms of utilization, but the judging group was most impressed by Gullaugar's taste quality.
Four different strains of potato were tested in processing of precooked potatoes. The strain Salome had best yield, but the strain Gullauga was best liked by consumers, which is in contrast with previous results. All four strains still qualified for processing after storage for almost 200 days at 5.7 ° C, although some strains had started sprouting. The strains Milva, Salome and Gullauga all had good yield, however, group of sensory panelist liked the flavor of Gullauga.
