The varietal improvement project led by EMBRAPA/CNPMF aims to produce resistant genotypes and has the following priorities: (1) continue the work of selection for disease and pest resistance, (2) seek a steady improvement in agronomic characters to promote greater productivity in the tetraploid hybrids generated, (3) initiate or support studies on the genetic variability of the Moko pathogen, Pseudomonas solanacearum race 2, in the Amazon basin, in combination with a search for resistance sources at the diploid level, (4) initiate or support research on fertilization of banana ovules in vitro, with appropriate histological studies as a guide, in the hope of greatly increasing the seed productivity of some parthenocarpic banana types, particularly the triploids, (5) seek the continuation of tests to determine the black leaf streak/black Sigatoka resistance of genotypes produced in Brazil, as much at the diploid as at the tetraploid level, (6) intensify studies on somaclonal variation of plants produced in vitro, by the use of RAPD markers as well as by mitotic analysis.
