This poses the challenge to participatory plant breeding (PPB) of identifying farmers that experience comparable conditions and needs, and therefore require similar varieties. Practitioners of PPB need methods for classifying farmers into homogenous groups with similar variety demands. This paper presents a statistical method for classifying individuals-farming households in this example-into homogenous but distinct groups. The method allows the use of different types of variables, provides a systematic approach to decide the number of groups present in the data, and assigns a probability that an individual belongs to a group. The method assumes that data have been collected from a sample of farmers in the target socioeconomic or agroecological environments. In the example presented, the method is used to divide a random sample of small-scale maize farmers in Mexico into homogenous groups T2 - Quantitative Analysis of Data from Participatory Methods in Plant Breeding ER -
