Abstract | ||||
Two field experiments were carried out during 1998/1999 and 1999/2000 seasons. This investigation aimed to evaluate twenty wheat genotypes under two different locations i.e. EI-Salhia which represents sandy loam soil and Hanout, Kafr Sakr District which considered light clay soil. The components of genotype x environment interaction and phenotypic stability were computed for number of days to 50% heading, flag leaf area, plant height. spike length, number of spike/m2, number of grains/spike, 1 OOO-grains weight and grain yield ardb/tad. The results clearly indicated highly significant differences among wheat genotypes, environments and their interaction. Wheat genotypes differed in their response to changes in environments, Genotypes No, 3 and 14 were stable and adapted under all environments for grain yield ardblfad. Moreover, the first genotype (No.3) shown higher developmental elasticity where gave higher yield and yield components under both favourable and unfaourable environments. Genotype No, 13 was adapted for favoura~ environments for spike length, number of grains/spike and grain yield ardblfcld. Meanwhile, genotype No.7 was adapted for less favourable environment for flag leaf area, plant height and grain yield ardblfad, | ||||
