Seed Germination and Early Seedling Vigor in Progenies of Inbred Strawberry Selections1

Abstract

Abstract Most progenies from intercrossed or outcrossed inbred selections of strawberry ( Fragaria × ananassa Duch.), germinated as well or better than a control outcross between 2 vigorous noninbred clones. Germination of an S 3 progeny was lower than the control. In general, inbreeding reduced seedling vigor while intercrossing or outcrossing of inbreds restored vigor. Germination total and rate as expressed by an index were unrelated to subsequent seedling growth.
