摘要

Chickpea (Cicer arietinum) is traditionally grown as a spring-sown crop in the Mediterranean region including Turkey. Precipitation in the region is insufficient and irregular, especially in spring. During spring, the moisture in the soil and rainfallcontinuously decline while drought and high temperature stresses consequently increase. Under these circumstances, yield of chickpea was constrained by drought, accompanied with high temperature stress. To escape drought stress, earliness is one of themost important mechanisms in spring-sown crop (Singhet al. 1994). Besides earliness, root characters are important in adaptation to drought environments. However, the study on root traits in chickpea using large number of genotypes (Krishnamurty et al. 2003) has been difficult owing to the time consumed and destructive sampling of plants (Gregory 1988). Maximum extraction of the limited available water in the soil could be achieved only by a deeper root system and early growth vigor in drought-prone environments (Saxena et al. 1993a, Wery et al. 1994). This study was aimed at identifying genotypic variations for root and shoot growth in chickpea mutants during seedling stage.
