Abstract Wheat is the major cereal crop in Egypt as well as all over the world. Egypt grew in 2018, 3,156,835 million faddan that produced 8,348,628 million tons of grains, with an average yield of 2,6446 tons per faddan (Agricultural Economic Affairs, Ministry of Agriculture ,Egypt,2018). With increasing population, it could hardly satisfy only 55% of the local requirement. This increasing gap between wheat production and consumption could not be achieved only through extending the wheat area due to limited cultivated area of Egypt. Thus, it needs to increase the productivity of unit area through adapting efficient breeding program. Moreover the genetically approach of studying growth attributes, at various stages, could help in understanding the genetic variabilities of wheat growth and development, that have impact on earliness. Exploitation of such genetic information, related to growth, may cause further breakthrough in yield level (Srivastava and Nema, 1993) |
