On the inheritance of spraign resistance in potato varieties

Summary

In evaluating a potato variety as a parent for breeding purposes use was made of the experience gained in cattle breeding. In order to ascertain the influence of for instance Komeet on Record, seedlings of the cross Komeet × Record were compared with Record itself.

It was found that Bintje and Engelum Y 226 exert a favourable influence on the spraign-resistance of the seedlings resulting from crosses using these varieties.

The writer suggests the collection of more data by working on a larger scale with the cooperation of many breeders and the Foundation for Agricultural Plant Breeding, in order to get a clearer perception of the value of potato varieties in breeding work for spraign-resistance.
