Effectiveness of field experimentation on bean varietal microlocation and evaluation of genotype-environment interaction
Main Article Content
Abstract
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.
