A History of the Recommendations Made by the PRCWRT

The Prairie Recommending Committee for Wheat, Rye and Triticale (PRCWRT) evaluates candidate cultivars (varieties) of wheat, rye and triticale and, upon the request of the owner or designate, makes recommendations to the Variety Registration Office, Canadian Food Inspection Agency regarding the suitability of the candidate for registration.

The attached file shows a history of their recommendations made from 1959 to March 4, 2014:   PRCWRT Recommendations 1959-PresentNote: some varieties recommended have been registered by CFIA since the file was last updated.

As you look through the list, you’ll see the number of varieties that were supported by the PRCWRT have increased over the years.  You will also note that even though a variety was supported by the PRCWRT, not all lines were registered (see comments column).

Is it okay to seed fall rye back into rye stubble?

Is it okay to seed fall rye back into rye stubble? I know the deadline to seed is Sept 15. Are there any pro/cons to seeding, say Aug. 15? How does rye do in loam soil? I’m thinking of doing a test plot on some land where I’ve never grown it before.

It is not recommended to follow fall rye with either fall rye or winter wheat because of problems with volunteer rye. Also, if ergot has been an issue, you should follow with a non-susceptible crop for at least a year. Fall rye is best seeded into stubble from a previous non-cereal crop that will allow trapping of snow to reduce winterkill risk.

Seeding fall rye too early usually results in reduced yield and lower 1,000-kernel weight. On the other hand, seeding too late can result in reduced yields, delayed heading, later maturity and lower bushel weight. Fall rye should normally have two to four leaves and up to one tiller before freeze-up, which generally means optimum seeding is in late August-early September. Insurance seeding deadlines for fall rye are Aug. 15 to Sept. 20 (full coverage), with an extended seeding period to Sept. 25 (20 per cent reduced coverage). For more information, contact your MASC agent.

Fall rye is adapted to a wide range of soil types and conditions. It’s a good choice for light, sandy, erosion-prone land, but will respond to better soil types and fertility.
