Abstract
Seedlings of perennial ryegrass from several inbred lines were treated with colchicine, and from the mixoploids produced some diploid tillers were recovered. When these diploid colchicine-treated plants were compared with their isogenic untreated diploids effects on agronomic characters due to the colchicine were discovered. These colchicine-induced changes have remained stable over seven years of vegetative growth and have now been shown to be sexually transmitted through a selfed-seed generation.
