Assessment of some genetic structures of Levantine corn under drought conditions

Abstract

Maize is one of the most important grain crops in Egypt and the world. It is used in the feeding of animals and poultry. It is also used in many industries, such as starch, oil, fox sugar, etc. Recently, Syrian corn has been used to feed people in Egypt by mixing it by 20% with wheat flour in the making of bread. This study was conducted for the purpose of determining the nature of the genetic control action governing the hereditary possession of corn bearing hydrolysis, through the evaluation of 7 pure strains of white Levantine corn and hybrids resulting from interbreeding under water stress conditions and the identification of the best drought-tolerant genetic structures under sandy land conditions. The results showed that the average behavior of seven genetic compositions of corn of plant elevation traits, height of allows, line number / glucose, number of grain / line, weight of 100 seeds and grain/acre yield. The results indicate that there are moral differences between the genetic makeup of the classes under study. Genetic constitution 5 has given the highest values in most of the characteristics under study, and has given the lowest values to the elevation of plants, which indicates the importance of this genetic structure and that it can be used to improve these qualities.
