| Abstract:
In the present study we report the interspecific hybridization as a breeding tool to produce novel ornamental varieties in Nierembergia. Two species were used in reciprocal interspecific crossing: N. scoparia and N. ericoides. Successful hybrids were obtained and fertility was maintained in successive generations. Quantitative and qualitative characteristics were evaluated in 57 hybrid clones from segregating progeny (F2). The results indicate that segregating progeny from interspecific hybridization between N. ericoides and N. scoparia supplied interesting variation as ornamental material absent in parental species. Seven clones with good ornamental characteristics were selected for future trials. | |
