Research Topic: Oat Breeding

  • Project Status: Completed
  • Abstract/Summary: The objective of this project was to demonstrate how seedling vigour of oats can be improved by screening out smaller less vigorous seed. Increasing the average seed size of a seed lot should result in greater emergence, improved stand establishment, greater competitiveness against wild oats, earlier maturity and greater yield.

Research Topic: Intercropping/Other

  • Project Status: Completed
  • Principal Investigators: Lana Shaw, South East Research Farm (SERF), Garry Hnatowich, Jessica Pratchler, Robin Lokken, and Chris Holzapfel, Brian Nybo
  • Project Dates: 2019 – 2021
  • Abstract/Summary: This project will look at how to grow oat and pea together as a grain crop, how to separate grain components using slotted screens, and the effect of varying oat seeding rates in intercrop with pea on yield and agronomic parameters.Peas and oats are both relatively low value crops in the rotation compared withcanola. They are both beneficial to have in a crop rotation in terms of nitrogen useefficiency and mycorrhizal associations. Intercropping oats and pea in a mixed graincrop may result in a more resilient and valuable product with reduced need forherbicides and nitrogen fertilizer. Oat may have beneficial effects on pea disease orreduce weed pressure, which has implications for herbicide-resistant weeds like kochia. An oat-pea intercrop may be agronomically and economically suitable for many of thecrop zones found in Saskatchewan. An intercrop may reduce the need for glyphosate applications by reducing weed competition and may also improve soil aggregate stability. This project is funded by the ADOPT program.

Research Topic: Variety/Trials

  • Project Status: Completed
  • Principal Investigators: Mike Hall, through AgriARM (Applied Research Management)
  • Project Dates: April 2021 – February 2022
  • Abstract/Summary: Many oat millers will no longer accept oats treated with pre-harvest glyphosate. Losing this harvest management tool forces many producers to leave oats standing in the field longer, creating a greater risk of poorer grain quality and higher harvest lost.The objective of this project is to help producers select milling oat varieties that are more likely to maintain yield and grain quality when harvested late. Lodging, shatter loss, grain quality and yield between six commonly grown milling oats will be compared between ideal and late harvest timings. This project is funded by the Saskatchewan Agriculture Demonstration of Practices and Technologies (ADOPT) program.

Research Topic: Insect/Disease/Weeds

  • Project Status: Completed
  • Principal Investigators: Dr. Shaun Sharpe with AAFC
  • Project Dates: April 2021 – Feb 2022
  • Abstract/Summary: The study objective is to characterize the dose response, interaction, and optimal mix of potassium nitrate and pyroligneous acid (liquid smoke) to determine the suitability of either pre-seeding or post-harvest germination stimulation of wild oat, volunteer barley, oats, and wheat. Wild oat is a strong competitor and can cause significant yield loss when emerging prior to cereals. The development of herbicide resistance in wild oats results in additional herbicide inputs and costs, as well as standard practices to control wild oat.

Research Topic: Intercropping/Other

  • Project Status: Completed
  • Principal Investigators: Jaswinder Singh, McGill University
  • Project Dates: January 2019 – March 2022
  • Abstract/Summary: This project will lay the foundation for a new genome editing method in oat. Genome editing allows plant breeders to make targeted improvements within a plant’s existing DNA. The major objective is to integrate CRISPR- based genome editing approaches with oat breeding for the development of future generations of oat varieties. The objectives are to ensure the agility of the oat research community to respond to new opportunities, and hopefully to integrate CRISPR- based genome editing approaches with oat breeding for the development of oat varieties that address new challenges in food security and environmental stress.
