In South Asia, peas are exposed to waterlogging at germination when grown as relay with monsoonal rice. Genotypic variation was evaluated in waterlogged relay cropping and controlled-environments. RNAseq was employed to reveal mechanisms of tolerance, and studied a RIL population and diverse-germplasm panel to find traits for possible use in indirect selection for WL tolerance. Conspicious variation in waterlogging tolerance at germination was observed in the field and confirmed under controlled environments. The tolerance of genotypes was associated with testa colour and testa integrity - linked with differentially expressed genes identified. Testa colour and integrity can effectively be used in indirect selection for waterlogging tolerance.
