Prospects for the development of F1hybrid varieties of perennial ryegrass (Lolium perenne) and other herbage grasses

Abstract

SummaryConsideration is given to the prospects of producingF1hybrid varieties of perennial ryegrass,Lolium perenne, and other herbage grass species for commercial use. In the light of the results of interpopulational hydridization in this and other crop species and of the technical and economic disadvantages inherent in other methods ofF1hybrid seed production, it is concluded that the development of interpopulationalF1hybrid varieties, by the field interpollination of parent populations, is a desirable and worthwhile breeding objective.
