To assist producers with variety decisions this fall, Manitoba Agriculture, Food and Rural Initiatives (MAFRI) and MCVET (Manitoba Crop Variety Evaluation Team) is publishing the most recent variety descriptions and performance data for fall rye, which includes data collected in 2009.
All fall rye varieties available for production in Manitoba have good winter hardiness if no-till seeded into standing stubble. Fall rye is less subject to winterkill than winter wheat, although winter damage can still occur.
Information on height and resistance to lodging, shattering and ergot are presented in the Long-Term Yield Data and Variety Description Table. When looking at the data, the Long-Term Yield column is the best indicator of how a variety will perform over a range of conditions. The “site years tested” column shows the number of sites where the entry has been compared to the check, Prima.
While data from single sites is often more interesting, individual site data, and even data accumulated over numerous sites in a single year must always be viewed with caution. When looking at the Yield Comparison Table, the grey shaded area lists the yield of Prima in bu./ acre below each site. CV is the Coefficient of Variation and it is an indicator of how uniform a trial is; the smaller the CV, the greater the chance that true differences were found between varieties in the trial. LSD stands for Least Significant Difference and it shows the percentage that individual varieties must differ by to be considered significantly different.
A complete data set for all MCVET fall rye sites, along with data for all crops, will be published in Seed Manitoba 2010 this December. Seed Manitoba is a collaborative effort between the Manitoba Seed Growers’ Association, Manitoba Agriculture, Food and Rural Initiatives and the Manitoba Co-operator.
