Majority of the area under wheat in Nepal is under Rice-Wheat system. Late heat stress is one of the main constraints of wheat production caused by high temperatures followed by hot dry winds during grain filling stage. Heat adversely affects the grain size and reduce grain yield. A total of four varietal improvement activities under Late sown irrigated conditions…………………
