A pot experiment was conducted with eight varieties of wheat grown under normal irrigation (60 AS' and moisture stress (30 ASW) conditions, to study the effects of different soil moisture regimes on flag II area, relative water content (R W C), water potential (at anthesis milk stages) and grain yield. Flag leaf ar RWC, leafwater potential and grain yield decreased significantly under soil water stress conditions, com pal to normally irrigated control. Genotypes K 8027,C 306 and K 65 showed more grain yield/plant than UP 201 K 8708, HD 2329, HUW 206 and HUW 234 under 30 available soil water conditions. K 8027 may ultimat, prove to be outstanding variety under moisture stress situation since it was able to produce the highest flag 14 Ilrea, higher leafturgidity, plant water status, grain weight/main ear, grain yield/plant and harvest index, was also observed that anthesis stage was more sensitive than milk stage.
