Summary

Triploids (2n=21) and aneuploids (2n=19, 20, 22) were obtained through in vitro culture of immature seeds from reciprocal crosses between diploid and tetraploid ryegrass. Tetraploid x diploid crosses were more successful than their reciprocals. Triploids and aneuploids had a high multivalent frequency at meiotic metaphase and were highly vigorous. It is concluded that endosperm failure leads to nutritional deficiency in embryo survival and germination. Value of triploids as a source of new variation in ryegrass improvement is discussed.
