Wheat is one the most important staple food crop in the world which is consumed by more than 40 percent of the gobal population. In this book we denoted the results of variability, path analysis and diversity of various yield and yield contributing traits under only three irrigation during whole season among the diverse genotypes. We discovered that the most important component characters in terms of variability, correlation, path analysis, and diversity under restricted irrigation conditions are the number of grains per spike, spike length, peduncle length, 1000 grain weight, biological...
