Drought is a major constraint in rice- growing areas of Asia. Identification of genomic regions containing QTLs governing drought tolerance traits is inevitable for developing novel genotypes with enhanced drought tolerance. A RIL population of 122 lines derived from a cross of Daggaddeshi/Danteswari was used for identification of QTL governing traits associated with yield was used in the study. A new QTL () linked to grain yield was identified in both stress and non-stress conditions. Several QTLs linked to different secondary traits associated with grain yield in stress condition were also identified. These QTLs can be used for further studies using marker assisted breeding for enhancing drought tolerance. |
