| Description
| - Pansy, Viola x wittrockiana, is a popular ornamental plant. Eff ects of polyploidy on phenotype and four pollination methods on capsule and seed set were studied using ten octoploid (2n = 8x) and two hexadecaploid (2n = 16x) genotypes, originating from induced mutagenesis. Principal component analysis, using 19 phenotypic, phenological and physiological characteristics, revealed that hexadecaploids showed larger diff erences to the corresponding standard cultivars than octoploids. Number of seed per capsule was similar among genotypes. Capsule set with open pollination was 32--64 %, with self-pollination by hand 18--49% and with cross-pollination by hand 14--43%, while no plant successfully set capsules with seeds under isolators if not pollinated manually. Th us, Viola x wittrockiana is self-compatible but requires an agent-mediation for successful pollination. Th e induced phenotypes were found stable over four generations. Hexadecaploids had more attractive phenotypes but fewer seeds than octoploids. However, variation in seed set enabled selection of plants with high fertility, and average seed set increased over generations. Th us, new varieties, fulfi lling aesthetic criteria as well as economic and agronomic traits, can be bred from induced mutagenesis.
