%X Single plants of subterranean clover (Trifolium subterraneum) were grown from seed of 13 commercial Seaton Park seed samples and of five pastures sown to Seaton Park at least 8 years previously. Most populations had several variants of Seaton Park, though the predominant genotype was that usually considered to be the Seaton Park strain - herein differentiated as Western Australian Seaton Park (W.A.S.Pk). The original Seaton Park - from the Royal Adelaide Golf Course in South Australia - differed slightly but clearly in several characters, including some seed isozyme patterns, from W.A.S.Pk. It was present in half of the populations, but at low frequencies (1-6% of the total). One genotype (strain S) comprised 20% or more of the populations from three commercial seed samples; it contained significant levels of the oestrogenic isoflavone formononetin. The origin of W.A.S.Pk remains unclear. The present commercial strain (cv. Seaton Park) is being re-built, based on W.A.S.Pk alone.
