Abstract
Heterosis over mid and better parents was estimated in twenty crosses of bread wheat involving three varieties viz., PBW 222, LU26S and Uqab 2000 and two lines viz., 8952 and 8961. 1000-grain weight showed maximum heterosis over the mid parent (20.96%) followed by number of grains per spike (13.97%), plant height (-7.00%), grain yield per plant (-23.70%) and number of tillers per plant (-31.22%). The maximum heterobeltiosis was recorded for 1000-grain weight (12.58%), plant height (-18.51%), grains per spike (-20.71%), grain yield per plant (-25.39%) and tillers per plant (-33.16%).
