摘要：

The aim of this study was to discover the geneic basis of drought tolerance, a double haploid mapping population, Drought Mapping Population 5 (DR. M.P. 5) was assessed for drought tolerance in hexaploid wheat (Triticum aestivum L.) under control and drought stress condition. The germplasm was planted under control and stress conditions. The yield and yield components were recorded. QTLs were detected by linking morphological data with genotypic data. Five drought tolerant wheat lines were found based on a thousand-grain weight, ranging from 49 to 62 g. Novel Quantitative Trait Loci (QTLs) for spike length and grain per spike were identified during the present study. The novel QTLs are of great importance as these may be helpful in finding such regions in genome, which are responsible for drought tolerance contributing characteristics. The D genome is the main allele which denote drought tolerance to hexapoloid wheat while A and B genome in durum contribute the stress tolerant characteristics.
