Abstract
The main objective of the present investigation was to study the variation , performance and stability parameters of yield and its components in forage sorghum genotypes, Sorghum bicolor(L.) Monch tested under eight environments. This investigation carried out in four Agricultural Research Stations, ARC, to represent most climatic conditions across the country during two seasons, 2008 and2009. These four locations were Sakha(Kafr El-Sheikh governorate), Gemmeiza( Gharbiya governorate), Sids(Bene Suef governorate) and El-Serw(Dommita governorate).Sixteen genotypes were grown in a randomized complete block design (R.C.B.D) with four replications under the eight different environments to evaluate all genotypes at three cuts. The genetic materials used in the present investigation included, piper black, Sids1, Sid2, Serw1and Serw3 were selected through breeding program, IS3192and IS3193 were import from ICRASAT, Gizal was sorghum saccharatum, Giza2 was common sudangrass, MN 4418, MN 2756, MN450, Rex Honey, Browly and Williams were imported from ICRISAT, through Sugar crops Research Institute and tested as forage crops, ARC, Egypt. Data were recoded on Fresh forage and dry forage yields (kg/plot), plant height (cm.) Number of stems per 0.15 m2. The first, second and third cut were taken aftar 60.100 and 135 days from sowing, respectively.
