Ploidy — Hybrid Ryegrass

Lolium x hybridum Hausskn.

The ploidy of hybrid ryegrass is classified into diploid (2n) and tetraploid (4n) forms, obtained through induced polyploidy. This indicator is a key marker of a variety's productive potential and the quality of the resulting forage.

In the reference 110 varieties crop Hybrid ryegrass, where this is mentioned in the description.

Hybrid ryegrass is a product of interspecific hybridization, with induced polyploidy being widely used to create high-yielding varieties. Compared to diploid (2n) forms, tetraploid (4n) forms are morphologically characterized by broader and darker green leaves, which allows for the identification of ploidy levels through external traits or laboratory methods.

The choice of ploidy level determines the cultivation strategy: tetraploid varieties are characterized by increased green mass yield, improved dry matter digestibility, and high forage energy value. Diploid varieties retain the characteristics of their parent species, while tetraploids also demonstrate increased adaptability to the impact of abiotic environmental factors.
