The potato cultivar "Tula" from crossing "Atlantic" x "12-9-95" was obtained in the 2004-2005 season at the National Institute of Agricultural Sciences, after 12 years of evaluation and characterization according to the Cuban potato breeding scheme. Clone 23-4-05 from population 19 was selected and named as cultivar "Tula". This has excellent agronomic and industrial quality characteristics: quick closing of canopy in field, light green foliage and vigorous stems. Moreover, this is semi-late and resistant to Phytophthora infestans under field conditions and moderately resistant to Streptomyces scabies. Their tubers are uniform with yellow skin, pale yellow pulp, with eyes of medium depth, high content of dry matter and a medium yield of 32.4 t ha-1, with more than 90 % of commercial tubers.

Keywords : breeding; processing; disease resistance; dry matter content.
