Abstract
The potential of inbreeding and selective hybridization, along with anther culture, for increasing homogeneity with 2 early flowering cultivars of Streptocarpus X hybridus

was examined. A 'Concorde' and 'Mixed Nymph' genotype expressed inbreeding depression within 2 generations, characterized by a reduction in corolla, leaf, and peduncle size, as well as an increase in floral deformities (flower part

fusions). Inbred populations contained individuals which resembled the parent cultivars for several morphological traits. Such could be selected by cluster analysis of important

traits, for the development of inbreeding depression resistant lines for hybrid production of more uniform, seed—propagated Streptocarpus cultivars. Reciprocal differences were observed among hybrids of first generation inbreds, suggesting that female parent selection is critical for certain ornamental traits such as corolla size and peduncle

length.
