Table 5 The percentages of variance (R2 ) in P.infestans resistance explained by the significant marker-trait linkages (T student test, p < 0.000) in (a) detached leaflet tests and (b) tuber slice tests.

From: Late blight resistance gene from Solanum ruiz-ceballosii is located on potato chromosome X and linked to violet flower colour
