| Summary: | This work is part of an intensive Program of Genetic improvement in Musa spp. through hybridi-zations, which holds the Research Institute of Tropical Viandas (INIVIT). For this were conducted pollen fertility tests in different cultivars of bananas and plantains and it was studied a set of combinations from preselected male and female parents from National Germplasm Bank of Musa, it is conserved “ex situ” in areas of Institute,
with the objective of to determine male and female fertility in some clones and the most efficient combinations to obtain new hybrids. It was obtained as a result that the highest rates of fertility were for bananas cultivars (AA) ‘SH-3142’ (95.1 %), ‘SH-3362’ (94.4 %). ‘Calcuta–4’ (99.1 %), ‘Paka’ (96.5 %) and ‘Pisang Jary Buaya’ (98.1 %), the latter reported by first time under our conditions as a new male parent and they were successful in obtaining hybrid most combinations made between cooking bananas and synthetic diploid or improved (‘SH-
3362’ and ‘SH-3142’). Triploid cultivar ‘FHIA-25’, to show fewer fertile grains (17.6) and produce seeds in all combinations, reaffirms its status as maternal line |
