‘In 1995, a breeding project was started to convert the normal unbranched inflorescence spikes of Lolium perenne into branched inflorescences. The concept was that by achieving a much higher number of floral sites on the inflorescence, higher seed yields might be obtained. This in turn might allow breeders to develop plants that had adequate seed yields with fewer inflorescences, which might increase the nutritive value of such plants around heading time.

¹Each germplasm is the product of a completed or significant breeding programme, but the breeders are not seeking Plant Variety Rights. Germplasms are available as “concept cultivars”, intended as research materials or for further localised breeding projects. Request for seed should be made to the corresponding author. Germplasm releases are not fully refereed.
