End Date: Jun 30, 2021
Continue screening of the NSGC of barley to identify new sources of resistance to BCOA, RWA and GB; transfer resistance genes to adapted malting barley backgrounds; progeny testing of newly identified BCOA resistant lines and if homozygous resistance is confirmed, develop genetic populations necessary for inheritance and genetic diversity studies; evaluate new resistant lines in preliminary yield trials; evaluate superior lines in advanced yield trials at several locations prior to germplasm/cultivar release; determine genetic diversity and genetic control of RWA, GB, and BCOA resistance in developed germplasm/cultivars; and monitor the adaptation of newly introduced invasive aphid pest, HGA. Begin development of winter malting barleys adapted to the Great Plains through the pedigree method.
Continue greenhouse screening of the NSGC of spring and winter barley for BCOA resistance; progeny testing of identified BCOA-resistant lines followed by transfer, through backcross breeding, of resistance into adapted malting barley backgrounds; if homozygous resistance is confirmed, validation of the greenhouse screening technique and rating scale for BCOA; conduct multi-state field surveys for the presence of HGA a new invasive aphid pest on barley. Make crosses to transfer malting quality into winter malting barleys adapted to the Great Plains and increase F1 from crosses to F2.
