DIAZ SOLIS, Sandra H; MOREJON RIVERA, Rogelio; LUCINDA DAVID, Donessa  e  CASTRO ALVAREZ, Rodolfo. Morphoagronomic evaluation of traditional rice cultivars (Oryza sativa L.) collected in grower farm from Pinar del Río province. cultrop [online]. 2015, vol.36, n.2, pp. 131-141. ISSN 1819-4087.

The research was conducted in Unidad Científico Tecnológica de Base (UCTB) Los Palacios belonging to the Instituto Nacional de Ciencias Agrícolas (INCA), with the aim of contributing to the enrichment and genetic diversity conservation of rice (Oryza sativa L.) by morphoagronomic characterization of traditional cultivars collected in grower farm from Pinar del Río province. Were evaluated a total of 13 cultivars, including 11 traditional and two improved using a randomized complete design with five repetitions. . In the development of the investigation twenty-five descriptors were used that included qualitative and quantitative characters, which were measured in flowering, ripening and postharvest stages crop. The obtained data were subjected to univariate and multivariate statistical analysis. Differences between cultivars for qualitative and quantitative characters were found. Were detected in the genotypes Andres, Bluebonnet, Estrella Roja and Caracol, interest characters such as earliness, plant erection, panicle length, compact and well emerged panicles, tillering capacity and slow senescence that could contribute to make progress rice genetic improvement
