Q&A with Potato Breeder Dr. Sagar Sathuvalli

By Sonia A. Hall, Center for Sustaining Agriculture and Natural Resources, Washington State University

This article is part of a series where we share insights from conversations that I had with public plant breeders across the Pacific Northwest about their breeding programs and how climate change considerations intersect with their work. Through these conversations, I wanted to better understand the complexities of the plant breeders’ world, where there are elements that already provide useful information about adapting to future climates, and where there are questions—about the climate in the future, or the plants’ responses, or production, market, or other factors affecting a particular crops’ future—that intersect or even overshadow questions about how to prepare for future climates.

Potato is a high-value, irrigated crop grown across Pacific Northwest states. It is affected by a range of pests and diseases, including many soil-borne pathogens. The need to break the cycle of some of these pathogens is a driver of crop rotation decisions. In my conversation with Dr. Sagar Sathuvalli, Associate Professor, Potato Breeding and Genetics at Oregon State University, it was clear that plant breeding had an important role to play in resistance to a wide range of pests and pathogens. He described a two-fold challenge to breeding for future climates. First, potato breeders don’t yet have good data on how climate change might change the dynamics of different pests and pathogens, and which might become greater threats in the future. And second, breeders must meet high expectations: neither yield nor quality can be compromised in pursuit of tolerance to climate-driven biotic or abiotic stresses. So here is how Dr. Sathuvalli is approaching these issues.

Maintaining yields under stressful climate-driven conditions is important in Oregon State University’s aroma hop breeding program, as in most breeding programs. However, two other aspects drive the work of Dr. Shaun Townsend, Associate Professor, Crop and Soil Science at Oregon State University. The first is how warmer (and maybe drier) springs could, maybe, help reduce the impacts of downy mildew, a “tough nut to crack” for breeding tolerance to diseases. Before I discuss my second take-away (it is about beer), see what Dr. Townsend had to say about breeding aroma hops for future climates.

Q&A with Barley Breeder Dr. Patrick Hayes

Barley, like wheat, can be sown in the fall, overwinter, and grow and mature the next season, or can be planted in the early spring, and have a shorter, quicker growing season. For a variety of reasons, however, spring barley is considered “the good one” for malting and producing beer. Yet as Dr. Patrick Hayes, Oregon State University’s malting barley breeder, works to develop barley varieties that will be grown under future climates, fall barley is key. The timing of growth and the resources it taps can help avoid a variety of issues that will otherwise impact barley yields and quality (whose main indicator is the percent protein in the grain). Read on for Dr. Hayes’s explanation of why fall barley is becoming increasingly attractive.

Q&A with Apple Breeder Dr. Kate Evans

By Sonia A. Hall, Center for Sustaining Agriculture and Natural Resources, Washington State University

This article is the first in a series where we share insights from public plant breeders around the Pacific Northwest on their breeding programs and how climate change considerations intersect with their work. These conversations are about understanding the complexities of the plant breeders’ world, where there are elements that already provide useful information about adapting to future climates, and where there are questions—about the climate in the future, or the plants’ responses, or production, market, or other factors affecting a particular crops’ future—that intersect or even overshadow questions about how to prepare for future climates.

Dr. Kate Evans, WSU.

I recently had some highly educational and thought-provoking conversations with Kate Evans, Professor of the Department of Horticulture and director of the Pome (apple and pear) Fruit Breeding Program at Washington State University. These conversations broadened my thinking on plant breeding and climate change from a focus on understanding to what extent plant breeders might be considering climate change in their breeding programs, to all the complexity of what plant breeding is about, how it fits into a much broader context of production and management practices that can help growers adapt to a changing climate, and the range of challenges and opportunities that face a crop—in this case apples—and its associated industry as we experience and prepare for the changes our climate will bring. Here’s what Dr. Evans had to say.
