Diversidad genética de cuatro materiales de maíz chococito en la zona baja del rio anchicaya, Pacifico colombiano

Abstract

Using methodologies based on participative research techniques, memory and uses were recuperated for 'chococito' maize varieties in the Anchicaya river area. The morpho-agronomic characterization permitted to study the main characteristics and the level of adaptation of the varieties to the environmental conditions. 20 out of 120 correlation coefficient were statistical significant. Six principal components explained 73% ofvariability among quantitative traits. Texture grain and aleurone color were the qualitative variables with high degree of discrimination among varieties. Using cluster analyses for quantitative and qualitative variables, two groups were established in each case. The dendograms for these four cultivars had shown similarity among them. Plant height, leaf area and number of grains per row permitted to determine the main variability between varieties, such as in maize hybrids and breeding varieties.
