RPR

Regenerating Perennial Ryegrass (RPR) is a group of cultivars bred from Barenbrug’s grass breeding stations that delivers unparalleled recovery from wear and a naturally self-regenerating growth habit. 

• Faster establishment compared to normal perennial ryegrasses, particularly ‘fill-in’ between disc-seeding lines or in golf divot repair
• Gives a very dense sward, excellent wear tolerance and unparalleled recovery after wear
• Added traction strength due to interconnected plants, RPR’s creeping growth habit helps fill in sand slits and drainage lines 

Normal perennial ryegrasses exhibit a purely tufted growth habit, with limited sidewards growth. Barenbrug’s unique RPR cultivar, Barlibro, produces determinate stolons (Fig. 1) (a stem that grows below the ground surface) as it establishes and grows.

The determinate stolons are growth shoots emerging from auxiliary buds at the base of each plant. When an RPR plant is damaged, creating space, determinate stolons will grow horizontally into the empty space and develop roots (Fig. 1). Each RPR plant connects to other plants and into the top layer of the soil; this produces a network of stolons. 

Our unique products that utilise the RPR technology - RPR Sport, RPR Golf, RPR Sprint - are blends of hard-wearing perennial ryegrasses and the RPR cultivar, Barlibro, for the renovation and construction of elite winter sports pitches, racecourses, and golf courses.
