RGT Silversurfer – “A Pretty Tidy Variety”

Exceptional disease resistance combined with very high yields are the hallmark of RGT Silversurfer, a new hard feed wheat that is up for recommendation this autumn.

Few people outside RAGT Seeds know more about RGT Silversurfer than Colin Lloyd, Agrii’s head of agronomy, who has been keeping a close eye on the variety in company trials.

“We work closely with RAGT early on in a variety’s life if we think it has promise, and RGT Silversurfer is no exception,” says Colin.

“We’ve certainly put it through its paces over the past couple of years and it has shaped up well.”


Overall, this season the variety was the highest scoring of all Group 4 RL Candidate varieties in Agrii’s new wheat sustainability index, which identifies varieties with the greatest agronomic strengths that offer least risk and environmental impact.


This index is based on scores for 11 key variety characteristics weighted according to importance – resistance to the three main foliar diseases, lodging (treated and untreated); orange blossom midge resistance; yield resilience and consistency; grassweed competitiveness; specific weight and latest optimum sowing date.


RGT Silversurfer has performed exceptionally well under high disease pressure over the past couple of seasons.

“Septoria tritici was late to get going, generally speaking, but when it did it came in with a vengeance,” says Colin. “We had two or three sites where it really took hold, but RGT Silversurfer held itself together in some pretty tricky situations.”
