Abstract:
The study was conducted using 16 F₁ hybrids, their corresponding 8 parents and one hybrid check (CSH 22SS) which were evaluated at three different locations of Andhra Pradesh covering three different environments viz., Agricultural College Farm, Bapatla; Regional Agricultural research Station, Lam, Guntur; Agricultural Research station, Garikapadu during rabi season of 2018. The experiment was conducted in a Randomized Block Design with three replications at all the three locations. The experimental data were analysed using Eberhart and Russell model based on these stability parameters, regression coefficient (S2di), mean performance (x̄) and linear response (bi). Bapatla location was found to be most favourable location for brix %, total soluble sugars, ethanol yield and seed yield. Guntur was the most favourable location for juice yield while Garikapadu was the favourable for fresh stalk yield. The hybrid H-11 is found to be suitable for unfavourable environments in respect of, grain yield and juice yield. The hybrids H-3 and H-4 were found to be more stable in respect of both Brix per cent and TSS per cent.
