Increasing the productivity and market value of pulse crops for arid organic conditions

In this project, we evaluated factors impacting productivity and product value in grain
legume crops in semi-arid organic farms. Specifically, we focused on 1) characterization of yield
and other agronomic traits in diverse grain legume crops grown in semi-arid organic
environments, 2) selection of breeding materials based on yield and other characteristics in these
same environments, and 3) understanding the genetics of unique seed types that provide a high
value to organic farmers.To this end, we evaluated a total of 72 varieties or breeding lines

20 to 20, in 2020

This project investigates 20 promising ancient and heritage grain varieties to measure performance for farm scale organic growing conditions and will increase available seed of these 20 unique varieties to a minimum of 20 pounds each in 2020. Data will be collected on weed suppression, lodging, disease, and pest pressure as well as yield and height and environmental conditions at two sites- Ketchum, Idaho and Paonia, Colorado.

Breeding disease-resistant heirloom-quality tomatoes

The object is to breed disease-resistant heirloom-quality tomatoes, especially those resistant to late blight and a number of other diseases. I have already crossed ten premiere heirloom tomato varieties—full-size red, pink, black, orange, and paste types—to the hybrid ‘Iron Lady’, which is resistant to late blight and a number of other relevant diseases. And I have developed the second-generation (F2) populations from each of these ten crosses.

Evaluation of selection methods and efficacy in on-farm breeding of organic wheat and oat varieties

The availability of crop varieties that are well-suited to organic management practices and to regional environmental conditions is increasingly recognized as crucial for the continued success of organic agriculture, including the ability of organic farmers to minimize environmental impacts and adapt to climate change. Participatory plant breeding (PPB), is internationally recognized as a methodology that works collaboratively with farmers to achieve this goal, but very few PPB programs currently exist in Canada.

Seeding a Culture of Innovation in Organics: Farmer-led breeding of peppers, broccoli and cucumber

This project supports three breeding projects in cooperation with the Ecological Farmers Association of Ontario’s Farmer-Led Research Program. All three projects focus on providing best practices to adapt to climate change by breeding varieties that are locally adapted to low-input organic systems for southern Ontario and the US northeast and meet identified needs of organic growers in the region. By supporting farmer-led breeding efforts for organic production, this project also contributes to an emerging but critically under-researched area of vegetable farming. 

Development and Assessment of Bacterial Wilt and Downy Mildew Resistant Cucumber Seedstocks - Year Two

In this project I will continue to assess downy dildew (DM) resistant cucumber seedstocks, with intensified focus on evaluating and advancing the lines I selected in 2018 from Common Wealth Seed Growers’ DMR breeding population. This population performed very well in our 2018 trials, having the highest yield and best foliage ratings in the DM trial, and above average performance in the bacterial wilt (BW) trial. Because I am increasing focus on cucumbers, I am not including melon research in this year’s proposal.

 

Evaluating the Effects of Seeding and Inoculant Rates on Weed Suppression, Nodulation, and Soil Health on Organic Lentil Production in the Northern Great Plains

Lentils are important for diversifying wheat-based cropping systems and are also beneficial in enhancing soil health. These benefits have contributed to the exponential growth in pulse crop acreage in The Northern Great Plains (NGP). There are several challenges facing organic lentil production. Lack of approved herbicide for use in organic pulse crop production provides a challenge to weed management.

Corn Earworm Management: A Survey of Organic Sweet Corn Growers

The objectives of this project are to attain information about the corn earworm management strategies of organic sweet corn growers. This information will be used to achieve two outcomes: creation of an extension publication about corn earworm management strategies, aimed at organic farmers, and collection of data that will inform longer-term efforts of developing earworm-resistant sweet corn cultivars for organic farmers.

Evaluation of Organic Strawberry Transplants for Organic Strawberry Production

Conventional strawberry nurseries that fumigate soils with methyl bromide and other synthetic chemicals prior to propagation are currently the main source of transplants for both conventional and organic production systems. While many organic strawberry growers have expressed dissatisfaction with having to use conventional transplants, organic transplants simply are not commercially available. In part, commercial availability of organic transplants has been limited due to a lack of tested varieties as well as a lack of supply during the traditional planting season.
