A native of the Isle of Wight in the English Channel, Seager Wheeler migrated to Saskatchewan in 1885. After working for a few years on his uncleís farm near Clarkís Crossing, he took up a homestead in the Rosthern district, specializing in seed production.
He first attracted public attention in 1911 as a result of winning the world championship for wheat at the New York Land Show. In the seven years following he won four more world championships with wheat produced on his farm.
Intensely interested in plant breeding, he originated varieties of wheat: Early Triumph, Kitchener, Red Bobs and four supreme. Two of these varieties, Kitchener and Red Bobs, made a significant contribution to the agricultural economy of Western Canada. Although his name is usually associated with wheat, he played an active role in the improvement of oats, barley and potatoes.
He joined the Canadian Seed Growersí Association in 1908 and took a leading part in its affairs throughout his lifetime. In 1919 his book, "Profitable Grain Growing", was published by Grain Growersí Guide. In recognition of his outstanding contribution to agriculture, an honorary Doctor of Laws degree was conferred upon him by Queenís University in the same year.
