Abstract
A field experiment was conducted at Nuclear Institute for Food and Agriculture (NIFA), Peshawar, to identify high yielding bread wheat genotypes against terminal heat stress in the central agro ecological zone of NWFP. The genotypes included in the trial were selected on the basis of yield performance and other agronomic characters under normal and late planting conditions from NIFA Observation Nursery (NON) sown during 2001-2002. For the confirmation of their desired traits the selected genotypes were again planted under the same sowing conditions during 2002-2003 using two different sowing dates as a separate factor. Statistical analysis of the data revealed that significant differences in days to heading, days to maturity, plant height, biological yield, spikes per m2
