Progeny of crosses among nine clones derived from hybrids of tall fescue ( Festuca arundinacea Schreb.) and annual ryegrass ( Loliurn multiflorum Lam.) were studied for perloline content. The data were analyzed by a modified partial diallel analysis. The results suggest that perloline is controlled primarily by a few major genes, with a high degree of dominance for low peroline. However, some genes with smaller effects may exist.
