Our laboratory conducts research related to the breeding of wheat (breed improvement). We're focusing spelt, a traditional variety that retains many primitive characteristics. For example, it's a non-free threshing kind of wheat and it has a long culm length. Spelt flour is expected to have useful properties that aren't found in modern varieties of wheat, such as adaptability to poor environments. However, many of its properties have yet to be rigorously evaluated. Spelt is being cultivated once again, mainly in Europe, due to its unique taste and its high nutritional value when baked in bread.
We aim to breed Hokkaido wheat that has the useful genes of spelt. For that, we evaluate genetic resources from around the world and discover and identify useful genes by using DNA markers and genome information. Our focus is on (1) the protein content and nutritive value (mineral content) of grains, (2) characteristics related to yield and adaptability, such as sprouting season, sprouting resistance, and lodging resistance (a property associated with culm stiffness), (3) the form and function of roots, which lead to improved phosphorus absorption, (4) the agricultural use of symbiotic relationships between arbuscular mycorrhizae and wheat. We also try to develop new “university brand” wheat varieties for bread that have the high nutritional value and rich flavor of spelt flour.
I'm from Kobe City, Hyogo Prefecture. I've been researching in Hokkaido since I've longed for Hokkaido and entered university.
