RosBREED2: Progress and future plans to enable DNA-informed breeding in the Rosaceae. Acta Horticulturae. 1172:115-118. https://doi.org/10.17660/ActaHortic.2017.1172.20.
Technical Abstract: Rosaceous crops provide vital contributions to human health and are economically significant in communities across the U.S. Industry stakeholders have given high priority to development of new cultivars that exhibit disease resistance and superior horticultural quality to mitigate production, handling and market risks. Rosaceous crop breeders have responded to the need for genetic solutions by using resistance from wild and/or unadapted germplasm, but few have achieved commercial success because of difficulties breeding cultivars with high fruit quality and disease resistance. The USDA RosBREED project addresses this need through a multidisciplinary effort that will enable breeding programs of rosaceous crops to routinely apply modern genomics and genetics tools to efficiently and effectively deliver cultivars with producer-required disease resistances and market-essential horticultural quality. The crops included are: apple, blackberry, peach, pear, rose, strawberry, sweet and tart cherry, and Prunus rootstocks. The Rosaceae-wide approach is based on the premise that working together will synergistically accelerate progress for all crops due to the ability to collectively address the shared biological and technical challenges. Progress and plans for the following project components will be presented: (i) knowledge about, and access to, alleles for disease resistance, (ii) strategies to efficiently combine multiple disease resistance and superior fruit quality alleles into parents of cultivar-generating families, (iii) knowledge about, and access to, additional alleles for horticultural quality, (vi) tools to unite genome-wide alleles for multiple traits into elite selections, and (v) knowledge of other components contributing to a cultivar’s genetic potential: genetic background and non-genetic effects.
