Hyola hybrid canola offers superior blackleg resistance

Hyola hybrid triazine tolerant (TT) canola varieties are showing superior levels of blackleg resistance compared to commonly grown open pollinated (OP) TT varieties, according to the GRDC 2019 spring blackleg management guide.

The industry publication assigns canola varieties one of nine blackleg ratings, from the highest rating of R (resistant) to the lowest rating of VS (very susceptible).

Varieties Hyola 350TT, Hyola 550TT and Hyola 559TT are rated R, R-MR and MR respectively, while popular OP TTs like ATR-Mako, ATR-Stingray, ATR-Bonito and ATR-Wahoo are rated MR-MS, MR-MS, MS and MS respectively.

The twice-yearly guide, published in autumn and spring, can help growers determine whether they are in a high-risk situation and what practices they can change to reduce or prevent yield loss from blackleg.

Its release comes at the perfect time for canola growers, some of whom are already planning their 2020 sowing.

Pacific Seeds, the producer of Hyola, continue to invest in research at its state-of-the-art blackleg screening glasshouse facility in Toowoomba, along with the intensive field screening program right across Australia’s major canola growing regions.

The company has established an industry-leading intensive blackleg screening program that is actively applied across all its parent lines and new hybrids under development.

The result is that Hyola hybrids in each herbicide tolerance group continue to demonstrate some of the highest adult resistance ratings possible in the industry – a major credit to the diligent and focused research team.
