Evaluation of banana varieties and hybrids under irrigation

Brazil has a great number of banana varieties, however a few of them attend completely the exigencies related to the consumers preference requirements, productivity and diseases resistance. The objective of this work was to evaluate banana varieties and hybrids in Guanambi (BA), in two productive cycles, in a completely randomized design. The genotypes evaluated were the varieties Nam (AAA), Caipira (AAA), Grande Naine (AAA) and Prata Anã (AAB) and the hybrids (AAAB) PA12-03, FHIA-01, FHIA-18 and SH3640. The characters analyzed were plant height; number of leaves in the flowering, in the harvest and in the cycles; number of hands and fingers and bunch weight. The variety Grande Naine stood out in both cycles, specially in characters that expressed the productivity. In the first cycle, 'Caipira' and the hybrids FHIA-18 and SH3640 obtained the best behavior, after 'Grande Naine', for bunch weight. 'Caipira' also stood out in number of fingers, while, in number of hands, the hybrids SH3640, FHIA-01 and FHIA-18 showed a good performance, overcoming 'Prata Anã'. SH3640 presented the largest number of leaves at the harvest, while PA12-03 was the most precocious genotype and had the minor stature. In the second cycle, SH3640 was one of the outstanding genotypes in the characters: bunch weight, number of hands and number of leaves in the flowering and in the harvest, loosing only to 'Grande Naine', in the two first characterers, and to 'Prata Anã', in the two last ones. In number of fingers, 'Caipira' stood out, overcoming 'Grande Naine'. PA12-03 was, like in the first cycle, the material most precocious, together with FHIA-18, and also presenting, with 'Nam', the second best stature. Plant height and bunch weight had an elevation, from the first to the second cycle, in the evaluated genotypes. All hybrids evaluated presented potential to be recommended as varieties.
