Narrative
GP-NC-WS 19 (IL-49) and GP-NC-WS 18 (IL-29) are highly resistant to the two major diseases impacting peanut production in North Carolina, leaf spot (LS) and tomato spotted wilt virus (TSWV). However, both are deficient relative to current cultivars in both pod yield and grade. Therefore, both are best classified as germplasm lines to serve as a source of improved disease resistance to future cultivars. Highly detailed information on disease scores, yield, grade, and plant morphological traits can be found in the accompanying JPR article.

Pedigree
Description:
The large-seed Virginia-type peanut cultivar 'Gregory' (PI 608666, Reg no. CV-62) was hybridized with the wild species A. diogoi accession GK 10602 (PI 276235) to produce sterile, triploid interspecific F1 hybrids. Cuttings of the sterile triploid were treated with 0.2% colchicine solution to the double the chromosome number and restore fertility at the hexaploid level. Hexaploids were allowed to self-pollinate for 11 generations until reversion to the tetraploid was suspected and supported by flow cytometry results.
