Table 5.

Summary of the resistance levels of rice cultivars to S. hermonthica and S. asiatica ecotypes in field and controlled environments (pre and post-attachment resistance). Cultivars are ranked Resistant (R), Susceptible (S) or Intermediate (I); based on NSmax (field) or the average number of attached Striga plants (controlled environment).

^aStriga ecotypes: Sh-Mb = S. hermonthica from Mbita (Kenya); Sh-Ki = S. hermonthica from Kibos (Kenya); Sh-Me = S. hermonthica from Medani (Sudan); Sa-Ky = S. asiatica from Kyela (Tanzania); Sa-US = S. asiatica from USA. IR49255-B-B-2 and Mwangulu are not shown as they were only tested in one field site and not in controlled environments.

^bInformation on post-attachment resistance is derived from Cissoko et al. (2011) and on pre-attachment resistance from Jamil et al. (2011b).
