Abstract

Somatic hybrids between potato and Solanum bulbocastanum, a wild diploid (2n=2x=24) Mexican species, are highly resistant to late blight, caused by Phytophthora infestans. Both randomly amplified polymorphic DNA (RAPD) and restriction fragment length polymorphism (RFLP) markers that are closely linked to the resistance have been noted by analysis of three different backcross-2 populations derived from two different somatic hybrids. With reference to previously published potato and tomato maps, resistance appears to be on the long arm of chromosome 8 and is flanked by RFLP markers CP53 and CT64. In a population of BC₂ plants derived from a cross between the BC₁ line J101K6 [(S. tuberosum PI 203900+S. bulbocastanum PI 243510) xKatahdin)]xAtlantic, late blight resistance cosegregated with RFLP marker CT88 and RAPD marker OPG02-625.
