Untreated RGT Saki plots are looking green and clean despite high yellow rust pressure in RAGT trials at the company headquarters near Ickleton in Cambridgeshire.
The variety, a Group 4 heavyweight newcomer on the 2020/21 Recommended List, is one of several popular varieties being grown next to yellow rust spreader plots. These plots consist of three highly susceptible varieties designed to catch and develop the disease and then spread it across the entire site.
“The spreaders have worked particularly well this season, which has been a good one for yellow rust,” says Tom Dummett, RAGT’s cereal and OSR product manager.
RGT Saki, along with stablemates RGT Silversurfer, RGT Quicksilver and RGT Galactus, all up for recommendation this autumn, have performed exceptionally well in the trial.
“Some other varieties are also holding up well, but others are performing below what you’d expect from their RL scores,” says Tom.
“We know how quickly rust races can evolve, and we may be seeing further evidence of this, but currently RGT Saki is certainly living up to its RL rating of 9 both here and at other sites across the country."
