This project will increase the effectiveness of selection and release of two-row hulled malting varieties, as well as develop quality selection criteria for hulless malting lines within the FCDC hulless breeding programs.
The objectives of this study are to increase the effectiveness of selection of two-row hulled malting varieties and to develop quality selection criteria for hulless malting lines within the Lacombe Field Crop Development Centre breeding program. This will include an expansion of Near Infrared Spectroscopy (NIRS) capability.
Developments – June 2016
TR14617, a two-row hulled barley, has good lodging and good disease resistance (Table 1). TR14617 is an early maturing line with yields 3% higher than AC Metcalfe and similar to CDC Copeland (Table 2). In two years of PRCOB cooperative testing and its first year of BMBRI collaborative testing, this line had good malting quality similar to AC Metcalfe.
Objectives for the upcoming year – June 2016
In 2016-17, FCDC will continue studies to improve our selection efficiencies for malting quality in two-rowed hulled and hulless barley. We are advancing promising two-rowed malting lines using marker work. We have continued to enhance the platform of markers we are using, and it is very exciting and encouraging work.
Resistance is not futile (May 15, 2014)
Activity #16 has allowed the breeders, biotechnologists, statisticians and quality teams to work together with industry on enhancing the effectiveness of selection of malting barley at the Field Crop Development Centre. During the project, Lowe was released, and this variety has great potential as a low DON (toxin from Fusarium), low protein, high yielding variety for the craft brewing market. As well several lines are in the Coop system, including the first FCDC hulless malting line, that if approved for registration will greatly expand the portfolio of malting barleys released by FCDC.
Having direct feedback from industry on our malting quality has been a great benefit to the program. Use of markers for quality and disease resistance has also allowed us to adopt new strategies for moving lines more rapidly through our FCDC breeding program.
In 2017, full scale malting by Canada Malting of Lowe has shown it to have good quality. Pilot malting at the Canadian Malting Barley Technical Centre has also shown excellent malting and brewing traits. Lowe was released because of its high yields, good malting quality for the all malt craft brewing market, and its disease resistance, especially to FHB, with DON levels on average similar to the best resistant checks and 50% of AC Metcalfe.

TR16629 is in its final year of collaborative testing in 2018. It showed great potential in its 2017 collaborative testing. We hope to receive support for registration in 2019. TR16629 was originally selected using marker assisted selection for disease resistance, and has moderate resistance for scald and FHB (Table 2).
There is a mega amount of genomic and phenomic data on grain quality, malting quality, disease resistance, and yield that has been collected over the four years of our project, that has the potential to be put into Dr. Rong-Cai Yang’s “Multiple trait genomic selection system (MTGSS) package” for gene discovery work.

FCDC has a strong base for continued release of malting barleys adapted to all growing areas of Alberta.
