New Durum Varieties Present Improved FHB Resistance

Two new durum varieties with improved Fusarium Head Blight resistance are on the horizon for Prairie producers.

Durum Breeder Dr Yeufeng Ruan says one of many new strains DT 2009 (generally known as AAC Schrader) is the primary durum line in Canada and the world with Intermediate resistance to FHB.

“As well as, AAC Schrader has excessive yield and straw power (much like Brigade) with excessive protein focus (much like Strongfield).”

The plant peak and maturity of AAC Schrader is much like AAC Cabri, it is rated as having “resistance to average resistance” to all rusts together with Ug99 stem rust.

Ruan says it additionally confirmed good drought tolerance and yield in 2021 below excessive drought circumstances, yielding 9 to 11 per cent greater than different cultivars.

AAC Schrader is now in seed multiplication and will likely be marketed by FP Genetics.

The opposite new durum line developed by Dr Ruan and his crew is DT2005, which exhibits improved Fusarium Head Blight responses in comparison with different present varieties.

Ruan notes that DT2005 additionally launched final yr exhibits excessive yielding, good high quality profile with additionally improved FHB resistance.

Another agronomic traits for DT2005 embrace a wonderful yellow pigment over present cultivars.

A 2.8 per cent increased yield than Brigade with comparable protein focus, plant peak, which is the same as AAC Cabri.

DT2005 has comparable straw power to Brigade and maturity much like Strongfield.

It options resistance to leaf rust, stem rust and stripe rust, and average resistance to Ug99 stem rust, with an improved response to FHB much like Brigade.

Whereas DT2005 has been launched, it’s nonetheless ready to be picked up by a seed firm for multiplication.

DT2005 and DT2009 (AAC Schrader) have been submitted to the Prairie Grain Improvement Committee Conferences for registration approval final yr by Dr Ruan and his crew at AAFC’s Swift Present Analysis and Improvement Centre.

Dr Ruan is evaluating his present work to find out if he will likely be placing ahead any new strains to the PGDC conferences, that are set to start in early March.
