Notes: aThe table shows the reproduction factor of ‘HAR1’ population from Kenya and ‘Ecosse’ reference population on six differential potato clones according to Kort et al. (1977). Data are means of two experiments (n = 10); bRo 1, 2, 3, 4, and 5 refers to the five pathotypes of R. rostochiensis according to Kort et al. (2077); c (+) indicates a reproduction factor (Rf> 1.0 (susceptible), and (−) indicates a Rf <1.0 (resistant).
