Construction of a high-quality genomic BAC library for Chinese peanut cultivar Zhonghua 8 with high oil content

摘要

BackgroundArachis hypogaea L. (2n = 4× = 40, AABB) is one of the most important oil and economic crop plants in the word. This species has the largest genome size of about 2,813 Mb among the oil crop species. Zhonghua 8 is a peanut cultivar planted widely in central China and has several superior traits including high oil content, high yield and disease resistance. A high-quality BAC library of Zhonghua 8 was constructed for future researches on the genomics of Chinese peanut cultivars.
