Abstract
Ten different wheat varieties/lines were studied to ascertain and compare the heritability, coheritability and genetic advance for grain yield per plant, days to anthesis, grain filling period, plant height, number of tillers per plant, spike length, grains per spike, lOOO-kernel weight, biological yield and harvest index. The highest value of coheritability was found between grain yield and harvest index followed by grain filling period while maximum heritability value (99%) was observed in days to anthesis followed by lOOO-kernel weigh (96%). The simultaneous selection of these characters would lead to increase in grain yield. Harvest index and grain filling period were the most important determinant for grain yield. While plant height and biological yield seemed to be least important for grain yield.
