Abstract
Drought is one of the most important abiotic stresses, which limits crop production in different parts of the world. Estimates of yield losses due to drought range from 15 to 60% which depend on geographical region and length of crop season. Plants adapt to drought environment either through escape, avoidance, or tolerance mechanisms. Chickpea is planted on 700,000 hectares in Iran. This area is fourth in the world after India, Pakistan and Turkey. Major chickpea area (95%) is planted in rainfed condition and is grown in rotation with cereals mainly wheat and barely. Most of the farmers grow this crop on marginal areas in the spring season. Terminal drought stress is one of the major yield reducer in chickpea in Iran. Major successes due to breeding have been achieved, in the selection for drought escape. The aim of present study was to find early maturity chickpea lines, which can escape terminal drought stress. The experiment material comprised 40 kabuli chickpea lines with susceptible check ( ILC 3279) in RCBD design with two replications at research stations of Kermanshah, Shirvan, Orumieh and Zanjan Province during 2002-03 and 2003-04. The experiments were sown late (10 April) by 20 days in comparison to normal sowing date for terminal drought stress. These materials were sent by ICARDA as CIDTN through Iran-ICARDA cooperation. The genotypes were recorded for drought tolerance score on a 1-9 scale on the basis of ICARDA recommendation. The result of pooled analysis of this study showed that difference between yield and drought tolerance of lines were significant. The results showed that 35 lines had significant difference at 1% level of probability over susceptible check for drought tolerance. These lines produced higher yield than check significantly. Superior lines for yield and drought tolerance were ILC 1799, ILC 3832, FLIP 98-141, ILC 3182, FLIP 98-142C, ILC 3101, ILC 588 respectively. ILC 1799 has produced the highest yield, which was drought tolerance with high adaptability, early maturity and large seed size.
