Lactal Perennial Ryegrass

Lactal is a tetraploid forage type perennial ryegrass selected for forage yield, digestibility, and good resistance to crown and stem rust. Its yield is characterized by aggressive regrowth and consistent second and third cut performance in hay applications. Bred from European material, it has strong winterhardiness that is suitable for harsher climates and excels in dry conditions.

Lactal offers premier quality hay, pasture or silage. Its excellent digestibility and feed value – attributable to breeding efforts to reduce heading (setting seed through summer) – is suitable for all classes of livestock, especially those with high nutrient requirements.

Distinct by Design: Making a Difference in Clubroot Research

Posted: Oct 20, 2020

It was August 2003, and Dr. Stephen Strelkov was beginning his career as a plant pathology professor at the University of Alberta, intending to specialize in Tan Spot disease on wheat, which had been the focus of his PhD and postdoctoral work. One month later, the first case of Clubroot in canola was reported in Alberta. That’s when Dr. Strelkov’s plans changed. He shifted to specializing in Clubroot research and helped create the Canadian Clubroot Differential set that has helped plant breeders across Western Canada develop next-generation canola traits for Clubroot resistance.

Distinct by Design: Let's Talk About Blackleg

Posted: Oct 06, 2020

Many people in the canola-growing business hear the word Blackleg and think only about how it might affect their yield, if they think of it at all. But there’s at least one person in Western Canada for whom that word sparks excitement and anticipation. Because rather than focusing on the challenges of the past, he’s focused on the gene-stacking potential of the future. That person is Sakaria Liban.
