Fig. 1From: Introgression of Root and Water Use Efficiency Traits Enhances Water Productivity: An Evidence for Physiological Breeding in Rice (Oryza sativa L.)The scheme of Multi-parent Marker-assisted backcrossing (MABC) to introgress root and WUE traits into IR-64 background. Foot note: Based on phenotypic and molecular diversity AC-39020 and IET-16348 were selected as donor parents for root WUE associated traits. IR-64 was selected as recipient parent because of its drought susceptibility. The donor parents were hybridised with recipient parents separately, to obtain the F1s. The resultant F1s were hybridised to get DCF1s. From this stage, plants were selected and backcrossed with IR-64 till BC3F1 stage. Further, selfing was done to identify the trait introgressed linesBack to article page
