Soil moisture is one of the most important determinants of plant’s seed germination, emergence and finally yield formation in arid and semi-arid zone (e.g. IRAN). In such a situation, the selection of a cultivar resistant to drought is the most important task. In this regard, a research at three levels (Farm, Greenhouse, Laboratorial) was conducted to study 10 genotypes with three improved back...
