Conteúdo: | In Southern Brazil, banana plants are subject to cold damage, in the autumn and winter. In some years, with temperatures between 0 and 6ºC, the leaves become progressively yellower due to chlorophyll destruction. This study was performed in Itajaí, SC, Brazil, in June 22 th, 2007, with the purpouse of investigating the differences among banana cultivars cold damage resistence. A scale from 1 to 5 was used to grade the leaves chilling intensity and to evaluate the cold damage level, for the total amount of the 18 phenotype. From all used varieties, clones and hybrids, the following distribution by groups was done: 4 AA group, 56 AAA group, 3 AAAA group, 28 AAB group, 21 AAAB group and 6 ABB group. The cold resistance inheritance degree was degree was greater than 90% in this study, however cold damage differences were observed among and within genome groups and subgroups. The B genome appeared to confer the greatest cold resistance to banana fruits.
