Diploid ryegrasses have two sets of chromosomes per cell compared to a tetraploid, which has four. Diploids combine yield and robustness, meaning that even in less than ideal conditions, they are more likely to deliver for your stock.
Delivering New Zealand bred and trialled ryegrasses that you and your stock can depend on:
Intensive farming systems require ryegrasses that produce bulk, high quality feed to drive animal performance and productivity. Tetraploid cultivars are a significant tool in helping achieve this goal, being naturally high in water soluble carbohydrates (sugars). A tetraploid plant has four sets of chromosomes per cell (a diploid has two sets), which simply means tetraploid ryegrasses are more palatable for livestock. Animals prefer tetraploids over diploids if they have a choice and often graze tetraploid ryerass more quickly and evenly.
