Breeding new sugarcane clones by mixed models under genotype by environmental interaction.

Sugarcane (Saccharumspp.) is one of the most important crops cultivated in the tropics and subtropics and plays a signifi cant economic and environmental role in Brazil. Twenty- four new clones were evaluated in different locations as potential models for recommendation as new varieties. The mixed model methodology, using the harmonic mean of the relative per- formance of genetic values (MHPRVG), facilitated the analysis of genotypic stability and adapt- ability, culminating in the recommendation of clones for each location. MHPRVG ranked clones RB92579, RB867515, SP81-3250, RB947520 and RB931530 as the best fi ve, and, addition- ally, clones with greater genotypic potential were identifi ed for each test in the six localities.
