Figure 2.
Five-week-old plants of Col, Ler, and RI lines derived from these ecotypes were exposed to cabbage looper larvae for 3 d. Larvae were allowed to feed at will until they stopped feeding. The inflorescences and leaves of Col and RI line 214 are resistant to cabbage looper feeding, whereas Ler and RI line 184 are sensitive and are almost completely consumed.
