Diploids or Tetraploid Ryegrass??
Diploids have 14 sets of chromosomes, Tetraploids have 28.
Tetraploids have larger plant cells, which means larger leaves and larger seeds. Therefore Tetraploids need to be sowed at 20-40% higher sowing rate.
Tetraploid varieties are faster out of the ground than Diploids because of higher energy reserve, but Diploids have a higher density which will help with weed control.
