In his words, Sean Myles is 鈥渟uper-passionate about food.鈥�

It鈥檚 a passion he has turned into a research mission. Under the banner of his  project, Dr. Myles studies the many different traits of apples that we enjoy with the goal of finding out ways to breed new apple varieties and help sustain our future food supply. In his mind, there's no better time to create a collection of as many different kinds of apples as possible with the goal of breeding new varieties that require less chemicals to grow, taste great and will sell out in grocery stores.

The work of his eight-person lab is far from genetic engineering and Dr. Myles is quick to make the distinction.

"We're not in the business of creating GMOs," he says. "We're figuring out how to combine the desirable traits from the thousand-plus apple varieties we currently have into new varieties and, in the end, preserve this precious biodiversity."

Dr. Myles, currently the Canada Research Chair in Agricultural Genetic Diversity and also an assistant professor in the Faculty of Agriculture, works out of the Apple Biodiversity Collection at the Atlantic Food and Horticulture Research Centre in Kentville, N.S., A few years ago, he and a few other researchers planted an orchard that he describes as the 鈥淯nited Nations of apples.鈥� Today, it's home to more than 1,000 apple varieties. Some of these apples we know as Macintosh and Honey Crisp, while others are wild varieties coming from places like Kazakhstan, and may have traits that could be used to make a new hit apple.

The majority of the team's work happens down the road from the orchard on computers, where they evaluate these traits, sequence the genomes and analyze the millions upon millions of letters making up the DNA of these apples. From there, they'll spend the next few years attempting to determine which two apples can be bred together to create a new hit variety.

Eventually, their research will be passed on to Canada's apple breeders, who will be the ones to plant the seeds, evaluate the tree's fruit and decide if they're worthy of being sold in grocery stores. It's a process that can take decades for breeders, but Dr. Myles is hoping that the team's research will shorten the process and that, soon enough, we'll have new apple varieties to enjoy.

When the time comes to test the most important trait 鈥� taste 鈥� Dr. Myles will have to call on other people to do it: although he鈥檚 got a passion for food, he's allergic to apples.

Compost Tea, Anyone?

Have you ever wondered what you could do with your compost? That there might be alternate uses for what lies inside your green bin?

Dr. Lord Abbey, an assistant professor with the Department of Plant & Animal Science is investigating just that.

鈥淎s a teenager who grew up in a city, the source of my food had always been a mystery to me. I wanted to do medicine but I was curious about the work of nature and the wisdom of our farmers. As a result, I decided to pursue agriculture, obtaining a BSc Agriculture in Ghana,鈥� he explained.Composting and compost use has been on his radar for quite a while now. 鈥淚t鈥檚 about time to explore the versatility of compost and its derivatives in other ways for its further promotion and value-addition and to open up new research and business opportunities,鈥� he explained. This will boost consumer confidence and offers a chance for producers to make a bit more money while safeguarding the environment.

Compost is used in a variety of fields and specialties including agriculture, horticulture and even for erosion control. Dr. Abbey is researching just how useful compost can be and is trying to find new and better ways to use it in agriculture.

His work includes the impact of drying and ionizing radiation effects on compost and plant response and compost tea formulation for flower and foliage vase-life extension.

Compost tea is exactly what it sounds like- compost is used and sits in water in something like a tea bag to attempt to get all of the nutrients out of it and the 鈥榯ea鈥� is then used to fertilize plants. This tea will be tested to see if it will lengthen the life span of grazing crops, also known as 鈥渇orages鈥�.

In addition to this, Dr. Abbey is working on an agro-economic assessment of the long-term application of green bin compost. This involves looking at how putting green bin compost in the soil will affect how productive the plant will grow and impact on soil health over an extended period of time.

鈥淭he goal of my research is to develop a sustainable, horticultural production system based on integrated and efficient crop management strategies and a food system approach to crop diversification,鈥� added Dr. Abbey.

Tea anyone?

Providing a healthier future for potatoes

By: Michelle Thompson

Whether mashed, baked, scalloped or fried鈥� potatoes are often considered a comfort food by many but this humble vegetable has grown to become an integral part of much of the world's food supply and the number one vegetable crop in the world.

Researchers at 果酱视频 University鈥檚 Faculty of Agriculture continue to work with growers to produce high quality potatoes that are not only environmentally friendly but adaptive to different climates.

Dr. Gefu Wang-Pruski, a professor of molecular biology in the Department of Plant, Food and Environmental Sciences at the Faculty of Agriculture has been doing field to fork research on potatoes for nearly 20 years. 鈥淚 try to help growers and consumers by producing potatoes that are environmentally friendly and that also provide a healthy food choice,鈥� explains Wang-Pruski.

Her research program looks at producing food smartly, not just for high quality consumption but with a positive environmental impact on the soil, air and water needed to grow our food.  The end result is that high quality nutritious potatoes can be grown with a minimum input of fertilizer, pesticides and fungicides.

鈥淭here is a great need in the Maritime region for supporting this industry to lead to better economic growth, farm gate value and improved industrial performances,鈥� explained Wang-Pruski.

Wang-Pruski is examining a number of different aspects in her potato research program including investigating and improving the quality of potatoes used for French fries by reducing the darker color that can often appear after cooking.  She is identifying the genetic markers of potatoes so they can be better adapted to growth in different climates around the world and is also working to improve potato production by managing the diseases and pests that can affect potatoes, such as late blight, Verticillium wilt, scab and wireworm. One of the major strategies being studied is to reduce the use of fungicides and pesticides that potato growers spray on their potatoes while they are growing.

鈥淭he strong support from the potato industry and positive feedback from growers makes my work more exciting and rewarding, which in turn influences everyone in my lab to become more committed to do excellent work,鈥� explained Wang-Pruski.   

Dr. Wang-Pruski is also leading a consumer research initiative that examines potato consumption patterns and consumer needs while developing marketing strategies for the industry.  

Packed full of vitamins, minerals and nutrients, environmentally friendly and adaptive to different climates, the humble potato may not be so humble after all!
