ABSTRACT

‘BRS F50’ (Cecilia) is a yellow skin potato cultivar for the fresh market, with good tuber appearance and versatile culinary use. The tuber has oval shape, shallow eyes, and light yellow flesh. It has a relatively high dry matter and medium-low glucose content, giving possibility even to use for processing into shoestring fries. The vegetative cycle and dormancy are medium. The maturity and tuber dormancy are medium. ‘BRS F50’ (Cecilia) shows a very low external and internal tuber disorder incidence, except growing cracks under varying soil humidity. It is moderately resistant to late and early blight, which make it also suitable for organic production. ‘BRS F50’ (Cecilia) was released by Embrapa in 2022, and is a product of its potato breeding program, developed by Embrapa Clima Temperado, in Pelotas-RS and Canoinhas-SC, and Embrapa Hortaliças, in Brasília-DF, Brazil.
