EFFECTIVENESS OF FIELD EXPERIMENTATION ON BEAN VARIETAL MICROLOCATION AND EVALUATION OF GENOTYPE-ENVIRONMENT INTERACTION

Abstract

Among breeding programs, the latest selective stages generally deal with several environments with experimental evidence, in which genotype-environment (GE) interaction is an important component of phenotypical variation. Participatory plant breeding (PPB) enables to achieve a significant integration: diversity fair and field experimentation to create an extensive and efficient experimental network; if varieties are evaluated on the farms previous to its extension, then GE interaction effects are positively observed when selecting the most adapted individuals to a specific ecosystem. Putting PPB into practice will enable to establish highly adaptable material to present low energy input conditions, by increasing yield and harvest quality; therefore, either economic, ecologic or social profits will be feasibly attained in peasant communities. Credit and service cooperative peasants from La Palma, Pinar del Río, developed spontaneity and creativity after attending bean biodiversity fair celebrated at INCA, so proving peasants�?? selection of the best genotypes for sustainability conditions. Some results show experimental evidence on GE environment, as an important phenotypical variation component and an effective use for field experimentation. It was also demonstrated on each farm that diversity improves after getting involved with PPB; besides, seeds become enough as a result of varietal introduction in the location.
