From: Marker Assisted Forward Breeding to Combine Multiple Biotic-Abiotic Stress Resistance/Tolerance in Rice

Fig. 1

Flow diagram depicting different steps of marker assisted forward breeding to combine multiple biotic-abiotic stress resistance/tolerance in rice Crossing program was initiated in WS2013 which involved crossing of recurrent parent (Swarna+drought, possessing drought tolerant QTLs namely (qDTY1.1, qDTY3.1) with four different donors possessing targeted genes or BB (Xa4, xa5, xa13, Xa21), blast (Pi9), BPH (Bph3 and Bph17) and GM (Gm4 and Gm8). The number over the chromosome represents the chromosome number of the respective donors. Through several rounds of inter-crossing, IC3F1 with desirable QTLs/genes combinations were obtained in WS2015. Further, MAFB approach was utilized to combine genes/QTLs for BB, blast, BPH, GM and drought tolerance
