Specific gravity of potato tubers as a character showing small genotype-environment interactions

Abstract

Specific gravity (which is a measure of dry matter content) of potato tubers is an important character for the potato breeder. A survey of published and unpublished data shows that it is but little subject to genotype-environment interaction. Probably, genotype x seasons effects are slightly greater than genotypes x locations effects. © 1973, The Genetical Society of Great Britain.
