The present invention relates to a new, distinct and stable variety of glyphosate tolerant perennial ryegrass, botanically known as Lolium perenne L. of the Poaceae family, and hereinafter referred to by the variety denomination 'JS501'. The present invention relates to glyphosate tolerant perennial ryegrass 'JS501' plants, as well as, progeny or hybrid plants, seed, plant parts, harvested products, tissue cultures of regenerable cells, and protoplasts obtained from the glyphosate tolerant perennial ryegrass plants or plant tissues of 'JS501', and containing morphological and physiological characteristics of 'JS501'. The present invention further relates to methods of producing non-transgenic and transgenic glyphosate tolerant grass plants and plant tissues from conventional breeding techniques and molecular techniques, wherein the produced glyphosate tolerant grass plants and plant tissues comprise the isolated perennial ryegrass 5-enolpyruvylshikimate 3-phosphate synthase (EPSPS) polypeptide of 'JS501'. |
