Why is this research important for Alberta ag?
The rate of genetic progress of plant breeding programs to raise seed yield and disease resistance is limited in part by their ability to generate new genetic variation. One of the avenues proposed to overcome this limitation is to access wild relatives and germplasm pools. This approach has been termed "pre-breeding".
Although effective at generating new genetic variation, pre-breeding limits cultivar development-driven breeding programs in that wild programs depend on the progressive accumulation of favorable additive alleles and any genetic recombination causes an inevitable regression to mediocrity. This regression, when using non-elite parents, results in a step back in yield and agronomic performance. The relatively new dry bean genome provides an avenue for exploring areas of chromosomes with low recombination.
Researchers hypothesize that it is possible to generate populations maximized for increased chances of recombination in these chromosomal regions. Therefore, the aim is to develop a DNA-marker aided system directed at uncovering "hidden genes" in the common bean genome, allowing for new variation to be generated to a greater extent among elite bean lines.
What benefits can producers expect from this research?
This research supports Alberta Pulse Growers goals of increasing crop yields by 20% by 2027, and to have a pulse crop option for every arable acre in Canada by 2027.
How will these research findings reach producers on-farm?
Results will be shared with industry stakeholders when applicable.
