![]() ![]() #Quickplan in spanish trial#Initial field trial evaluations of the new cultivars in New Zealand and Victoria, Australia, are promising. Maize breeders have been successfully exploiting hybrid vigour in their breeding programmes for over 70 years – which has contributed to maize’s superior rates of genetic gain compared with perennial ryegrass. ![]() This will allow breeders to exploit hybrid vigour in perennial ryegrass, which hasn’t been possible until now. While this breeding method is at the early stage of development, initial results are promising.ĭairyNZ is investing in the development of new hybrid perennial ryegrass cultivars as part of a research programme led by Australian organisation DairyBio, a joint venture between Agriculture Victoria, Dairy Australia and the Gardner Foundation.Recent advances in genetic mapping mean plant breeders can now select perennial ryegrass lines suitable for hybrid breeding, based on a method first proposed in the 1970s. ![]()
