What constitutes the 鈥減erfect apple?鈥� How do we grow the perfect apple and where do we find it?

Dr. Sean Myles and his team in the Myles Lab are looking closer at this. Dr. Myles, an assistant professor at 新加坡六合彩开奖直播鈥檚 Faculty of Agriculture and the Canada Research Chair in Agricultural Genetic Diversity, is looking at a number of different ways to accelerate the breeding of different plants and animals with desirable traits.

鈥淥ur research ranges from fundamental to applied,鈥� Dr. Myles explains. 鈥淲e develop novel analysis tools to get genetic information from plants and animals and look at their DNA. And we figure out ways to pick out the 鈥榳inners鈥� early in the breeding process and to toss out the ones that will never succeed in the market.鈥�

Originally from New Brunswick, Dr. Myles earned his Bachelor of Arts from Saint Thomas University. He then changed to science and completed his Master鈥檚 degree at Oxford University in England and a PhD at the Max Planck Institute for Evolutionary Anthropology in Germany. Dr. Myles then returned to the Maritimes alongside his wife to pursue his research career in genetics of plants and animals.

Dr. Myles explains that his team looks at DNA from plants and animals and chooses parents with desirable traits to use for breeding. Normally, hundreds or thousands of offspring are generated by a breeder but only a select few ever achieve commercial success. This process is laborious, time consuming, and expensive for breeders. Although Dr. Myles and his team are looking at a number of different plants and animals, such as grapes, mink, cacao, cannabis and salmon, Dr. Myles鈥檚 focal organism is the apple. Dr. Myles鈥檚 lab is housed in Kentville, Nova Scotia at the Atlantic Food and Horticulture Research Centre in the heart of the Annapolis Valley where the apple industry is thriving.

鈥淲orking out of the Kentville research station surrounds us with superb federal scientists and hundreds of acres of orchards and greenhouses,鈥� Dr. Myles says. 鈥淲e also work closely with breeders and growers who understand exactly how to make seed, grow seedlings and manage large apple orchards. I have a number of students and post docs working with me as well.鈥�

With over 1,000 different apple varieties and 2,500 apple trees growing on site, Dr. Myles鈥檚 team measures at least ten apples from each tree. The apples go through a machine that measures and analyzes weight, firmness, and acidity. The machine also extracts juice and pulp to be analyzed. The data is recorded automatically and saved using barcode readers. Once all the apples are analyzed, Dr. Myles and his team decide which fruits hold the most desirable traits. They analyze the DNA of the fruit and decide which varieties should be crossed together and used as parents in breeding programmes.

鈥淗ere in Kentville, we have established one of the most diverse collections of apples in the world,鈥� Dr. Myles explains. 鈥淲e鈥檙e trying to breed apples that are resistant to disease. If the apples are resistant to disease then growers won鈥檛 need to use as many chemicals which is more cost effective. We also want to develop apple varieties that are well-suited to Canadian growing conditions.鈥�

Dr. Myles鈥檚 end goal is to breed new crops faster and more efficiently.

鈥淲e want to be able to send better apples to the grocery store,鈥� Dr. Myles says.

Ideally, Dr. Myles wants to be able to develop the perfect apple.
