Agronomic performance and blackleg disease reactions of yellow-seeded Brassica napus canola
The development of low fibre (yellow-seeded) Brassica napus canola cultivars and hybrids is a major focus of canola breeding research at the Saskatoon Research Centre of Agriculture Canada. Early generation interspecific derived true breeding yellow-seeded lines were low yielding and repeated backcrosses to black-seeded elite cultivars and lines had to be made to improve yield, blackleg resistance, standability and seed quality of yellow-seeded lines. We utilized the winter rape cultivar Express of NPZ Germany, to incorporate winter rape genetic material into spring annual lines through cross breeding. Selected spring annual lines derived from crosses with Express were crossed with the AAFC yellow-seeded line Rsyn 2-11 to develop agronomically improved, blackleg resistant, yellow-seeded lines through pedigree selection in progeny from these crosses. F7 yellow-seeded lines derived from these crosses had improved seed yield, were highly resistant to blackleg and had acceptable maturity under Canadian short season growing conditions. Our research proved that winter rape can be successfully used in the breeding of agronomically improved, high quality, yellow-seeded spring B. napus lines for production in Canada.
