Abstract
Tetraploid cultivars of perennial ryegrass are slowly gaining popularity for fodder and pasture in north-western Europe. Breeding of new cultivars relies on colchicine treatment of young diploid seedlings, selection of tetraploid non-chimaeric individuals, intercrossing, evaluation, and finally selection of half-sib families as a basis for new synthetics.
