qDTY12.1: a locus with a consistent effect on grain yield under drought in rice por Mishra, Krishna Kumar, Vikram, Prashant, Yadaw, Ram Baran, Swamy, B.P. Mallikarjuna, Dixit, Shalabh, Cruz, Ma Teresa Sta, Maturan, Paul, Marker, Shailesh, Kumar, Arvind

“…The positive QTL allele for qDTY 12.1 was contributed by tolerant parent IR74371-46-1-1.In this study, qDTY 12.1 showed a consistent effect across environments for high grain yield under lowland reproductive-stage drought stress in the background of popular high-yielding but drought-susceptible recipient variety Sabitri. qDTY 12.1 was also reported previously [Crop Sci 47:507–516, 2007] to increase grain yield under upland reproductive-stage drought stress situations. qDTY 12.1 is the only QTL reported so far in rice to have shown a large effect against multiple recipient genetic backgrounds as well as under highly diverse upland and lowland rice ecosystems. qDTY 12.1 can be successfully introgressed to improve grain yield under drought of popular high-yielding but drought-susceptible lowland as well as upland adapted varieties following marker-assisted breeding.…”
