Development and characterisation of Brassica napus-Sinapis arvensis addition lines exhibiting resistance to Leptosphaeria maculans

Intergeneric Somatic Hybridization Between Brassica napus L. and Sinapis alba L.

“…In addition to intergeneric hybrids between B. napus and S. alba produced by protoplast fusion (Primard et al 1988;Lelivelt et al 1993), somatic hybrids between B. napus and S. arvensis have been obtained successfully (Snowdon et al 2000;Hu et al 2002). In the present study, we use electrofusion to produce hybrids between B. napus and S. alba, showing a relatively high pollen fertility ranging from 66% to 77%.…”

“…et De Not. were recovered (Snowdon et al 2000). Further work on the identification of disease resistance in progenies with a high erucic acid content is in progress.…”

Plant Breeding: Assessment of Genetic Diversity in Crop Plants and its Exploitation in Breeding

“…Intergeneric sexual hybrids between B. napus and Sinapis arvensis containing novel genes for resistance against blackleg disease on chromosome additions and introgressions were analysed via GISH by Snowdon et al (2000). Selfed BC 3 progenies included fertile plants exhibiting high seedling and adult plant resistance associated with the presence of an acrocentric addition chromosome from S. arvensis.…”

Interspecific Hybridisation between Wild Relatives and Brassica napus to Introduce New Resistance Traits iinto the Oilseed Rape Gene Pool

“…In Table 1 (PLÜMPER 1995). S. arvensis appeared as useful and valuable source of blackleg (L. maculans) resistance to oilseed rape (B. napus), because this species contains resistance to an isolate which has been found to overcome resistance originating from species with the Brassica B genome, until now the major source for interspecific transfer of blackleg resistance (SNOWDON et al 2000). Regarding Alternaria resistance B. elongata appeared as worthless source, because the weak resistance of the hybrid is completely lost after two backcrosses with B.…”
