Initiation of genomics-assisted breeding in Virginia-type peanuts through the generation of a de novo reference genome and informative markers.

ABSTRACT:

Introduction

Virginia-type peanut, Arachis hypogaea subsp. hypogaea, is the second largest market class of peanut cultivated in the United States. It is mainly used for large-seeded, in-shell products. Historically, Virginia-type peanut cultivars were developed through long-term recurrent phenotypic selection and wild species introgression projects. Contemporary genomic technologies represent a unique opportunity to revolutionize the traditional breeding pipeline. While there are genomic tools available for wild and cultivated peanuts, none are tailored specifically to applied Virginia-type cultivar development programs.

Methods and respective results

Here, the first Virginia-type peanut reference genome, "Bailey II", was assembled. It has improved contiguity and redu
