Meal quality improvement in Brassica napus canola through the development of low fibre (yellow-seeded) germplasm
The importance of the yellow seed trait in improving the feed value of canola meal through fibre reductions has been reported in various Brassica species by several researchers over a number of years. A strong correlation has been reported between seed colour and meal fibre reduction, in particular reduction in lignin content. Research at AAFC Saskatoon has utilized various sources of yellow seed colour genes in related Brassica species, and these were incorporated into adapted spring annual lines and cultivars through interspecific crosses. Interspecific F1 plants were repeatedly backcrossed to B. napus canola followed by reselection of true breeding yellow-seeded phenotypes after each backcross for several inbred generations before the next backcross was carried out. The resulting yellow-seeded lines were field tested under Canadian prairie growing conditions for several years. In all cases, fibre contents were strongly correlated to seed colour with lowest fibre contents observed in lines with strongest expression of the yellow seed trait. Intensive breeding work will be required to develop agronomically superior yellow-seeded (low fibre) canola cultivars and hybrids.
