Abstract

The present investigation was conducted to identify the stable cultivars across different environmental condition. Seventeen genotypes of which fourteen were in the final stage of multi-location secondary adaptation trials of the plant breeding program and three commercial varieties were evaluated in five different locations. The stability parameters regression coefficients (βi) and mean square deviations (S2di) were estimated for cane yield using the Eberhart & Russell's (1966) model. The pooled analysis of variance showed highly significant variances for environments (E), Genotypes (G), and GxE interactions. The results showed that there were highly significant (p <; 0.001) variations among the genotypes, environments and GxE interaction for cane yield. The top four high yielding genotypes were found to be LF82-2122, LF60-3917, LF82-2244 and LF57-5104. The first two genotypes had higher yield and stability statistics. Thus, from the present study it is concluded that for cane yield, the genotypes LF82-2122 and LF60-3917 can be recommended for adoption as the two most superior promising varieties for cultivation on all soil types in Fiji.
