Genomics‐assisted breeding for successful development of multiple‐stress‐tolerant, climate‐smart rice for southern and southeastern Asia

Abstract Rice ( Oryza sativa L.) in rainfed marginal environments is prone to multiple abiotic and biotic stresses, which can occur in combination in a single cropping season and adversely affect rice growth and yield. The present study was undertaken to develop high‐yielding, climate‐resilient rice that can provide tolerance to multiple biotic and abiotic stresses. An assembled first‐crossing scheme was employed to transfer 15 quantitative trait loci (QTL) and genes— qDTY 1.1 , qDTY 2.1 , qDTY 3.1 , qDTY 12.1 (drought), Sub1 (submergence), Gm4 (gall midge), Pi9 , Pita2 (blast), Bph3 , Bph17 (brown plant hoppers), Xa4 , xa5 , xa13 , Xa21 , and Xa23 (bacterial leaf blight)—from eight different parents using genomics‐assisted breeding.
