Single row plots with 25 seedpieces in 1994 and ten in 1995, were spaced regularly with spreader rows of White Rose to ensure uniform disease pressure. Relative susceptibilities against Phytophthora infestans US-11 in 1994, and a genotype in 1995 now being verified, were statistically compared by ranking areas under disease progress curves (AUDPC). NDA203-2, A8495-1, A81386-1, A84180-8, and A81473-2 ranked significantly lower in susceptibility than Russet Burbank in 1995. Russet Burbank is generally regarded as intermediate in susceptibility to late blight. Brador was more severely affected in 1995 than in 1994. When incidence of tuber blight was compared, NDA2031-2 had the highest incidence of blighted tubers for both years. |
