Numerical taxonomy of maize landraces: comparison between experimental designs

| Sumario: | [EN] Seventy three maize (Zea mays L.) landraces from Northwestern Spain were grown according to two different experimental design.The first one (design A) was a randomized complete blocks design with two replications per trial at two locations for two years. The second design (desing B) is simpler than the first one: the populations were grown at one location without replications for three years. Numerical taxonomy of these landraces was made according to results of the field trials using the different experimental designs. Clustering, after principal components analysis on the basis of 11 quantitative traits, showed that the two maize landraces classifications are quite similar. For this reason when the number of populations is high, a simple design may be more efficient in numerical classification of maize landraces. |
