Computation of Heritability for Some Multigenic Traits in Bread Wheat

Wheat is the most important cereal crop used directly as human consumable commodity by the major portion of world's population. An adequate staple food supply is the first pre-requisite in any country for social and economic stability. Wheat is the most important grain and a staple food for more than one third of the world's population. Large number of products and by products are obtained from this king of cereals. F2 populations of seven cross combinations Lasani-2008 Iqbal-2000, Lasani-2008 9432, Lasani-2008 9436, Lasani-2008 9444, Iqbal-2000 Lasani-2008, Iqbal-2000 9432 and Iqbal-2000 9436 involving cultivars/ lines Lasani-2008, Iqbal-2000, 9432, 9436 and 9444 were studied to determine the heritability and expected genetic advance in order to explore and utilize the hidden genetic potential so that new high yielding and better adapted cultivars can be developed in order cope with the rapidly changing environment and global demand of food with minimum inputs.
