Cultivated peanut (Arachis hypogaea L.) is a widely cultivated commercial plant in the world, which is also an important source of protein and edible oil. Discovering distributing and genetic diversity of high oleic acid germplasm in China peanut (Arachia Hypogaea) core collection is important to peanut high oleic acid breeding. There were forty accessions of germplasm that mean oleic acid content of two years is over 57%, which contains six accessions of ssp. fastigiata (var. vulgaris, 6), thirty-three accessions of ssp. hypogaea (var. hypogaea, 25 and var. hirsute, 8) and 1 intermediate. Except for 7 accessions coming from ICRISAT, 1 accession coming from America, 1 accession coming from Japan, and 1 accession coming from Korea, the other come from 12 provinces in China. We also discoverd three accessions germplasm with high oleic acid and oil content, which are Zh.h4094 (oleic acid=66.70%, oil content=54.99%), Zh.h4029 (oleic acid=63.50%, oil content=55.58%) and Zh.h4319 (oleic acid=59.70%, oil content=56.04%). And yield being over 3000 kg/ha had 10 accessions genotypes, and the ranked first third were Zh.h0883 (4086.06kg/ha), Zh.h1182 (3955.00kg/ha) and Zh.h2910 (3741.00kg/ha). Based on botanical and yield traits, the first five principal components (PCs) explained 81.17% variation, and based on dendrograms produced in NTSYS-pc 2.10e software, the varieties were classified into six groups in value being 0.1942. So, there was abundant genetic diversity of high oleic acid in Chinese peanut core collection. Varieties of high oleic acid Acquired was one strategy to improve oil quality of peanut and to develop high oleic fatty acid using plant breeding techniques
