Research Abstract

Wheat cultivars belonging in west Japan eco-type showed high grain yielding with a heavy kernel weight, maintaining high photosynthetic activity and high grain growth after mid-grain filling period. They also have a lot of reserve material in culm and use it to support the high grain growth rate. The West Japan eco-type genetically have the dominant character that accelerates the potential of photosynthetic activity with a lot of grains in a spike. That might stabilize the yielding in wheat under unfavorable condition.
