Narrative
Meier-Jansky-Halterman Blight Resistant (BR) Clone. BR85 is from a segregating population derived from a cross between the disease resistant parents +297 and K41 is being released as germplasm with resistance to both early blight, caused by Alternaria solani, and late blight, caused by Phytophthora infestans. The source of resistance to early blight in +297 is the wild species S. palustre and late blight resistance in K41 is conferred by the RB gene from S. bulbocastanum. This clone yields well at a temperate zone latitude. In addition to containing heritable resistance to both early and late blights, this clone possesses multiple other desirable agronomic traits, is fertile, and readily crosses to cultivars.

Description:
K41 x +297
  • Meier, A., S. Jansky, & D. Halterman. 2015. Germplasm release: three potato clones incorporating combined resistances to early blight from S. palustre and late blight from S. bulbocastanum into a S. tuberosum background. Amer. J. Potato Res. 92:410–416. Note: Three clones in a segregating population derived from a cross between the disease resistant parents +297 and K41 are being released as germplasm with resistance to both early blight, caused by Alternaria solani, and late blight, caused by Phytophthora infestans. The source of resistance to early blight in +297 is the wild species S. palustre and late blight resistance in K41 is conferred by the RB gene from S. bulbocastanum. These clones, named BR3, BR5, and BR85 (BR for Blight Resistant), yield well at a temperate zone latitude. In addition to containing heritable resistance to both early and late blights, these clones possess multiple other desirable agronomic traits, are fertile, and readily cross to cultivars
