RGT Atlantis

New RGT Atlantis – a spring barley with the ability to withstand waterlogging to achieve high yields

RGT Atlantis is new waterlogging tolerant barley with high yield potential in the medium and high rainfall zone areas. These areas with high yield potential can also experience periods of transient inundation during the growing season and this can limit the yield potential significantly.

RGT Atlantis has been bred from RGT Planet combined with a native waterlogging tolerant barley. This cross enables the plants to withstand periods of waterlogging via introduced structures called “aerenchyma”. Normally waterlogged soils are low in oxygen and these aerenchyma allow oxygen to remain in the roots during extended periods of waterlogging and keep the plants growing.

It has a similar yield potential to RGT Planet when under non-waterlogged conditions but can significantly outyield RGT Planet (up to or more than 20%) when under waterlogging pressure.
