Abstract

Wheat as a principal crop in Iran and mostly grown under arid and semi - arid conditions, hence irhas low productivity. To evaluate DROUGHT TOLERANCE.and productivity of 12 improved WHEAT CULTIVARS under RAINFED CONDITIONs, a field experiment was conducted at research farm of College of Agriculture, University of Tehran, Karaj, Iran, in 1999-2000, in a randomized complete block design with three replications. Each plot contained nine rows with 25 cm apart and seven m length. The final harvest area was 10.5 m2 (7 rows, 6 m long each). As moisture conservation practices were not performed in fallow year (before sowing), the crop was irrigated only once before seed germination. Total precipitation during the growing season was 200 mm. The improved WHEAT CULTIVARS comprised of six dryland varieties and six irrigated ones. The attributes recorded were- grain yield, grain weight, spike length, plant height, tiller number, and dates of stem elongation, heading and maturity. The coefficient of correlation between grain yield and plant height spike length and grain weight showed the important effects of these characters on yield under RAINFED CONDITIONs. Similarly, the negative correlation of grain yield with date of heading (r=-0.38*) and maturity (r=-0.29*) indicated that earliness enables the cultivars to escape drought towards the end of growing season. The cultivars Ghods, Rashid and Cross - Omid produced the highest yields, but Rashid was the earliest in maturity. Sardari, a well - known dryland cultivar, also produced high yield and had the highest total number of tillers and grain weight, under RAINFED CONDITIONs.
