Rice is the main source of carbohydrates in Cuban population’s diet; therefore, great efforts have been dedicated to breeding studies on this crop. In this sense, a methodological procedure was developed to obtain three rice cultivars, which were planted along with their progenitors under field conditions and agronomically characterized by using 32 qualitative and 19 quantitative descriptors. Results showed a significant and positive correlation between agricultural yield and panicles per square meter and full grains per panicle, whereas a negative correlation with rice Blast effects. Thus, the use of hypocotyl length is suggested as a selection marker in early seasons. All cultivars, were able to form a large number of fertile tillers, despite showing a short-term cycle, which enabled them to achieve the highest yields, with the help of full grains per panicle and 1000-grain mass components
