Stratification of the state of Santa Catarina in macro-environments for bean cultivation

The purpose of this study was to suggest a division of the State of Santa Catarina in macro-environments forexperimentation and bean production. Data of the traits grain yield and plant cycle were evaluated in 10 common beangenotypes grown in nine environments. The data were submitted to the Student-Newman Keuls test, to detect differencesbetween environments, and the Best Linear Unbiased Prediction, to predict the environmental values. The results showed: (a)differences between the regions of Santa Catarina for the traits grain yield and plant cycle, which had a significant positivecorrelation of 0.26 (b) Based on the genotypes and environments studied the state can be divided in two macro-environments(MA1 and MA2) and four micro-environments (MI1, MI2, MI3 and MI4). The state of Santa Catarina may be roughly dividedin at least two macro-environments for the recommendation of new cultivars.
