Outline of Final Research Achievements

Stable production of wheat is important under the global climate changing. Unequal distribution of precipitation causes hazardous drought and severe waterlogging problem in many production areas and may lead to a drastic reduction in economic yield. The wheat plant having deep root system or shallow root system is one of the essential factors to avoid water stresses. On the other hand, root system is generally expressed as a quantitative trait governed by many genes, and in a few cases these genes have mapped to specific chromosome regions in wheat. In the present study, we conducted QTL analysis for root growth angle at the seedling stage using recombinant inbred lines (RILs) derived from the cross between cross between parental lines showing contrasting phenotypes.
