Sugarcane breeding: VII. Evaluation of clones obtained by hibridizations in 1980 and selected in Jaú region, state of São Paulo, Brazil

Seven sugarcane clones obtained in crosses made in 1980 were tested in four locations and two Oxisol soils at Jaú region. The commercial varieties NA56-79, IAC67-112, IAC70-22, SP70-1143 and SP71-1406 were used as controls in trials planted in randomized blocks. The genotipes were evaluated in three harvestings, from plant cane trough second ratoon. The following parameters were considered: cane and sugar yield, fiber% and pol% cane. All clones showed inferior in sugar content than the controls, but five of them showed at least better performance in cane yield than var. NA56-79 which acted as the worst control for this character. The clone IAC80-3062, showed better sugar productions than NA56-79. This clone can be recommended as a late-of-season variety for the region.
