| 0 | PI 669445 | 'GP-NC WS 16' | Arachis hypogaea L. | North Carolina, United States | S9 | | | 2013 | DEVELOPED | | | | | | Cultivar | This line was tested extensively by the N.C. Agric. Res. Servo (NCARS) from 2006 through 2012 in disease evaluation tests. It has unique alleles introgressed from the diploid (2n=2x=20) wild species, Arachis cardenasii Krapov. and W.C. Gregory. The germplasm line is also unique in that it exhibited multiple disease resistances superior to the germplasm lines derived from A. cardenasii (GP-NC WS 12 and its antecedent GP-NC WS 1) that were released earlier by NCSU. Resistance to multiple diseases included early leaf spot (ELS), Cylindrocladium black rot (CBR), Sclerotinia blight (SB) , and tomato spotted wilt (TSW) . Th is line was used as a parent in crosses with runner-type cultivars Tifrunner and Florida-07 to develop a set of recombinant inbred lines (RILs) exhibiting variation for leaf spot reaction. This line should provide unique, improved germplasm for breeders interested in multiple disease resistance and in expanding the germplasm pool of A. hypogaea. | 1913554 | PI 669445 |
| 1 | PI 669446 | 'GP-NC WS 17' | Arachis hypogaea L. | North Carolina, United States | S9 | | | 2013 | DEVELOPED | | | | | | Cultivar | This line was tested extensively by the N.C. Agric. Res.

Resistance to multiple diseases included early leaf spot (ElS), Cylindrocladium black rot (CBR), Sclerotinia blight (SB), and tomato spotted wilt (TSW). SPT 06-07 also exhibited drought tolerance in field and greenhouse studies. Thus, it can be concluded that this peanut germplasm line derived from a diploid wild species has multiple biotic stress resistances, specifically for ElS, CBR, SB, and TSWV and also abiotic stress resistance. This line should provide unique, improved germplasm for breeders interested in multiple disease resistance and in expanding the germplasm pool of A. hypogaea. | 1913555 | PI 669446 |
