[The breeding of strawberries suited for freezing : I. Breeding potential and ecovalence of two "freezing" characteristics].
Heritability in the broad sense, the expected genetic advance with selection and the repeatabilities for two freezing characteristics were estimated in strawberry clones (Fragaria ananassa Duch.) over several years. The freezing characteristics were extravasation of juice and texture of berries after thawing. It could be shown that after 12-15 years of breeding and selection there was still much genetic variance. An estimation of ecovalence for these characteristics showed that ecovalence depends on genetic diversity.
