Evaluation of indicators for the early selection of the height character in Musa spp.
Journal Title: Biotecnología Vegetal - Year 2004, Vol 4, Issue 4
Abstract
In the plant breeding programs attended by Biotechnology and using the induction of mutations becomes necessary to work with big populations of plants to guarantee bigger possibilities to be successful in the work. For what to have a selection system that allows to carry out the same one in acclimatization phase would allow to shorten the outlines of improvement and to diminish the populations size notably to evaluate in field phase, what would bear to diminish the expenses in the whole process of studies clones them. With the aim of determining possible morphological indicators that could be used as markers for the selection of low bearing in the clones of the FHIA were studied in conditions of acclimatization different cultivars and banana mutants, being evaluated several morphological characters as: the height of the plant, number of leaves, long and wide of the penultimate emitted leaf, as well as the long of their petiole and the distance between two serial leaves. It was also evaluated the height of the plants under conditions in vitro when they were subcultivate in a culture medium with different concentration of AG3. The results indicate that inside the evaluated morphological characters, those that more early allowed to distinguish among plants of low bearing were: the long of the petiole and the height of the plants and that the moment of the selection should be to the 60 days. Not differences were observed between genotypes when they were subcultivate in the culture medium enriched with AG3.
