WESTERN WOLTHS, the extreme annual form of Italian ryegrass (Lolium multiflorum Lam.), is a fodder grass which orginated in the Netherlands (De Haan, 1955). Thirty to forty years ago it was widely used in Canterbury but its use died out with the advent of the certification scheme and the availability of good perennial ryegrass-white clover pastures. Saxby (1956) states that the questionable value of Western Wolths ryegrass has not warranted its inclusion in the certification scheme, and that in 1956 genuine seed was practically non-existent on the New Zealand market.
