Abstract:Water deficit is a crucial factor causing huge loss to rice productivity. The present study aimed to develop a multiple stress tolerant genotype by pyramiding drought tolerant yield QTLs qDTY 1.1 and qDTY 3.1 into high yielding rice variety Samba Mahsuri Sub-1(SMS) through marker assisted pyramiding. To achieve this six introgression lines of SMS carrying qDTY 1.1 (SAB) were crossed with DRR-50, an Essentially Derived Variety of SMS carrying qDTY 3.1 . The SAB lines are taller than SMS due to tight linkage bet… Show more
