| Popis: | Stability and adaptability of 14 early maturing sugarcane clones were evaluated at 11 locations in the State of Parana, in the plant cane and ratoon cycles, by the AMMI method. By AMMI2, 59.44% cumulative variance was explained in plant cane and 54.22% in ratoon cane by the first two principal components of tons of pol per hectare (TPH). For genotype RB966928 the TPH was medium to high, phenotypic stability high and adaptability general, recommending this early maturing clone with wide adaptability for northern Parana. The genotype-environment interaction was lowest in Paranavai and Mandaguacu (most stable locations), where the ranking of genotypes was more reliable than the means of the environments tested. |
