Interpretive Summary: ‘Pembroke 2014’ is an early maturing, semi-dwarf soft red winter wheat cultivar released by the Kentucky Agricultural Experiment Station for its strong resistance to Fusarium head blight, high yield potential, excellent test weight, and resistance to lodging. The prevalent grain crops rotation in Kentucky and the mid-south is corn, followed by wheat followed by double-crop soybean (Glycine max ). Planting wheat into corn stubble puts the crop at risk for Fusarium head blight, or head scab, since the fungus that causes this disease is harbored in corn stubble. The rows that gave rise to Pembroke 2014 were identified as carrying the resistance alleles at a major genetic locus for scab resistance called Fhb1. Pembroke 2014 was tested in replicated yield trials in numerous locations in Kentucky and other eastern states.

Technical Abstract: ‘Pembroke 2014’ is an early maturing, semi-dwarf soft red winter wheat (Triticum aestivum L.) cultivar that was released by the Kentucky Agricultural Experiment Station for its strong resistance to Fusarium head blight, high yield potential, excellent test weight and resistance to lodging. The prevalent grain crops rotation in Kentucky and the mid-south is corn (Zea mays L.), followed by wheat followed by double-crop soybean (Glycine max ). Planting wheat into corn stubble puts the crop at risk for Fusarium head blight, or head scab, since the causal fungus for this disease, Fusarium graminearum Schwabe, is harbored in corn stubble. The headrows that gave rise to Pembroke 2014, tested as KY03C-1237-32, were identified as carrying the resistance alleles at a major scab resistance QTL, Fhb1. Pembroke 2014 was tested in multi-location replicated yield trials in Kentucky in 2009 -2010 and has been tested from 2011 to the present in the Kentucky Wheat Variety Trial. It was also tested in the Uniform Eastern Soft Red Winter Wheat Nursery at 26 locations in 2011-12 and 2012-13, and in the Uniform Northern Scab Nursery in 2011 and 2014.
