Outline of Final Research Achievements

Growth and yield of crops are significantly affected by changing global environment. Heading time is one of the important traits to achieve the maximum yield in wheat and barley, but is becoming unstable mainly due to yearly fulctuation of temperature throughout the growing season. In this study, we first identified wheat and barley cultivars whose heading time varies largely depending on the year, and then identified the causal gene(s). A wheat breeding line 'Chogokuwase' is an extra early heading line and its heading date is accelerated by warmer temperature in wheat. By map based approach, using segregating populations derived from 'Chogokuwase' x 'Kinuiroha', we identified that the causal gene is PCL1 and triple recessive homozygote become eatra early heading. In barley, HvPhyC mutant allele, which is commonly found in the Japanese early maturity cultivars, proved to cause unstability of heading time depending on the temperature condition during winter.

Academic Significance and Societal Importance of the Research Achievements

出穂期はムギ類の生産性に直結する重要な形質であり,世界の研究者が遺伝研究を精力的に展開している.しかしながら,気候変動下での出穂期不安定性に着目した研究はほとんどなく,学術的に重要な発見をできたと考えている.また,出穂期不安定化遺伝子を特定できたことにより,今後は育種現場においてDNAマーカー選抜により希望遺伝子型を容易に選抜できるので,地球規模での温暖化や気候の不安定化に対応可能なムギ類新品種の育成を加速化できると考えている.
