Narrative
Late leaf spot disease is an omnipresent peanut foliar disease that causes significant yield loss to peanut production. Integrating host resistance to reduce yield loss and management costs from this disease is highly desirable. In addition to disease resistance, market demand for high oleic peanut is on the rise due to its improved oxidative stability and health benefit. Previously, a recombinant inbred population from Florida-07 x GP-NC WS 16 (crossing number C1801) segregating for both late leaf spot resistance and high oleic traits was used to perform genetic mapping for late leaf spot resistance by QTL-seq analysis. Three QTL regions on chromosomes B03, A05 and B05 were identified and KASP markers flanking these regions were validated through a field-test on genotypically selected sister lines. Two recombinant inbred lines (TifGP-5 and TifGP-6) with top levels of field resistance to late leaf spot were selected from this population for release. Both lines possess the resistance alleles of all the genetic markers. TifGP-5 is normal oleic whereeas TifGP-6 is higholeic. Releasing these recombinant inbred lines packaged with molecular markers provides the peanut breeding community with genetic resources that can be utilized through marker assisted breeding.
