VINENT, Enrique y FAJARDO, Odelín. Parámetros agrícolas de ocho cultivares de algodón (Gossypium hirsutum) obtenidos en Cuba. Cienc. Inv. Agr. [online]. 2007, vol.34, n.2, pp.151-158. ISSN 0718-1620. http://dx.doi.org/10.4067/S0718-16202007000200008.
The correlations of the following variables were determined for eight cultivars of cotton (Gossypium hirsutum) obtained in Cuba: feather and raw cotton yields, boll weight, plant height and plant perimeter and the number of bolls per plant. Feather and raw cotton yields were negatively correlated with plant height; in this same way, plant height and plant perimeter correlated with the number of harvested bolls per plant. Boll weight did not correlate with the studied variables. By means of applying multivariate analysis techniques and variance analysis, promising cultivars were selected. Significant differences were obtained among cultivars using seven biological parameters: feather and raw cotton yields, plant height and plant perimeter, ginning rate, boll weight and the number of harvested bolls per plant. The highest feather and raw cotton yields (5,575 y 2,353 kgha-1, respectively) were achieved with the cultivar L-48, followed by the cultivars L-3, L-6 and L-44 and the highest ginning rate (42%) was achieved with L-48. In conclusion, cotton cultivars L-48; L-3; L-6 and L-44 were the most promising cultivars, and will be further tested under commercial conditions
