Abstract
This investigation was conducted at Sakha, Gimmeza and Sids experimental stations in two successive seasons 199912000 and 200012001, to estimate stability parameters in five introduced genotypes of ryegrass (Lolium multiflorum L.) for green and dry forage yield. Mean squares of genotypes, environments and genotype by environment interactions were highly significant for green and dry forage yield. The all mixtures of Berseem with ryegrass gave the highest green and dry forage yield comparing by planting ryegrass in pure stand. Planting ryegrass with 10 Kg.lFed. in mixture gave the highest green yield at Sids SI. in the 199912000 season. Caramba gave the highest green and dry forage yield. For both characters, nonsiginificant values of bi revealed average response for all genotypes except Caramba for green forage yield. All genotypes showed significant non-linearity S2di. for green forage yield as well as the genotype Mt 1465 Primora for dry forage yield .. The four genotypes l.e. Caramba, Mt 337 Tewera, Mt380 Terwatco and Clipper were most promising and of practical utility for forage production under both poor and good management conditions and these could be used as a stable and high yielding genotypes in breeding programs
