Wheat is the most important cereal crop, cultivating throughout the world. Wheat has always been subjected to extensive and ceaseless research so as to maximize grain production but also to improve grain yield per unit area. Wheat Yield could be increased through selection for better performance of yield components or development of improved genotypes. Leaf rust is the most serious disease. Three types of rust occur on wheat i. e. leaf rust, Stem rust and Stripe rust. So far, nearly 58 leaf rust and 40 stripe rust resistance genes have been identified and varieties containing these genes are resistant to these diseases. The book describes the molecular and morphological study of 38 Pakistani wheat genotypes. Four Leaf rust resistance genes i. e. Lr10, Lr26, Lr34 and Lr47 and twelve different morphological characters are studied here.
