MARTINEZ CRUZ, Michel; ORTIZ PEREZ, Rodobaldo; RIOS LABRADA, Humberto  y  ACOSTA ROCA, Rosa. Evaluation of variability of a Cuban collection morphoagronomic corn (Zea mays L.). cultrop [online]. 2011, vol.32, n.4, pp. 35-43. ISSN 0258-5936.

In our country, the corn is cultivated from the time of the aboriginal ones and it constitutes a basic food in the human nutrition, of the livestock and the birds; it is the second cereal of importance and has high consumption preference for the population. In Cuba, six races of corn exist with a high diversity, which has been broadly studied. The present work was carried out in a sample of 106 local varieties, these local varieties were included conserved in situ in peasants' properties and conserved ex situ. The objective of the study was to evaluate the degree of variability of the collection; using for it 16 characters. The obtained results allowed to detect the existence of variability in the sample. It was demonstrated that the evaluated collection of corn presented variability due to the difference among genotypes, to the plurality of origins, handling and environmental conditions in that this cultivation is developed in Cuba. Also, in the studied collection, the variability of the evaluated characters is moderate, due to the selection that the peasants carry out on them. The most variable characters were the incidence of Spodoptera frugiperda (Smith), height to the superior ear and weight of a hundred seeds.

Palabras clave : corn; morphoagronomic variability.
