Adaptabilidade e estabilidade fenotípica de genótipos de cana-de-a？úcar no estado de Minas Gerais

the objective of this research was to evaluate the adaptability and phenotypic stability of genotypes of sugarcane in the state of minas gerais, brazil. there had been evaluated 15 genotypes in nine environments. the experiments were conducted in a randomized block design with three replications. to discriminate the genotypes the variable tph (tons of pol per hectare) was used. these values corresponded to the average of two cuts. the results showed that the check rb867515 presented greater general adaptability and phenotypic stability, followed by genotype rb987935, which had the highest average and high general and specific adaptability to favorable and unfavorable environments that may be suitable for commercial cultivation.
