| # PI 675011 @ USDA-ARS (USA) INFO | United Kingdom, England (developed) | Durum wheat Kronos was crossed to the Kronos mutant line T4-2235 which carries a splice acceptor site mutation in the A genome homoeologue of the TaGW2 gene (mutation G2373A). After the initial cross, four backcrosses were performed selecting progenies carrying the mutant gw2-a1 allele. The lines were then self-pollinated and homozygous mutant and homozygous wild type sibling lines were selected. | The BC4F3 sibling lines were grown in replicated glasshouse and field trials in the UK (Norwich) and US (Davis) and evaluated for grain weight and size. Lines carrying the gw2-a1 mutant allele had significantly increased thousand grain weight due to both wider and longer grains when compared to the isogenic sibling lines carrying a wild type allele at GW2-A1. | |||||
