ARIAS VARGAS, Yailen et al. Genetic diversity of maize (Zea mays L.) from Pinar del Río and Guantánamo by using of RAPD. Rev. Protección Veg. [online]. 2018, vol.33, n.1, pp. 00-00. ISSN 2224-4697.

The genetic variability among 32 maize (Zea mays L.) accessions collected in different regions of Pinar del Río and Guantánamo, Cuba, and 5 commercial varieties was analyzed by using RAPD markers. The dendrogram resulting from using Ward's method and Jaccard's distance showed the formation of four groups that are related to the origin of the accessions and the phenotypic characteristics of the grain which was corroborated with a factorial correspondence analysis. This result allowed knowing the genetic variability in the maize crop among the places studied, which is an advantage for breeding programs, the conservation of the germplasm bank, and the management of pests and diseases.
