Understanding Tetraploid Technology A Grass For All Seasons – By Jayne Leyland, Portfolio Director, Origin Amenity Solutions.
A new generation of amenity tetraploid perennial ryegrasses offer unparalleled qualities for sports pitches and playing fields, with proven benefits in addition to wear tolerance such as cold temperature growth, fast recovery, high root mass and superior stress tolerance.
If you have not
yet discovered tetraploids, how and why are they so exceptional?
Ploidy – refers to the number of complete sets of chromosomes within the nucleus of each plant cell. Perennial ryegrasses bred for amenity use were all
Robust development – a tetraploid cultivar begins its’ journey as seed selected from an amenity diploid cultivar with desirable characteristics. A few grammes is treated with
a natural plant hormone
(colchicine) which doubles the chromosomes.
tetraploids produce larger, take several tetraploid offspring
The resultant high-
energy seeds from which plants are grown and multiplied in isolation. It may of
generations to
yield historically diploids,
meaning two paired sets of chromosomes within each cell. Tetraploids have four paired sets of chromosomes, for example, chloroplast, and this physiological doubling of chromosomes explains how tetraploids deliver enhanced performance benefits.
Energised – increased cellular chloroplast benefits the plant by boosting chlorophyll production for energy absorption and processing. The outcome is a high energy, robust, hard-wearing, healthier plant with improved stress tolerance and recovery capability, even in cooler temperatures.

stable, viable seed for use in field testing.
Potential new cultivars
are pushed to the limit and vital characteristics such as growth habit, wear, disease and drought tolerance, mowing height and visual merit are assessed. Only one or two cultivars from early selections make it through this rigorous process
and those uniform and stable. successful
candidates must conform to DUS protocols,
