To evaluate the genetic variation in self-compatibility in different cultivars of Eruca sativa (“rocket salad”), we used three methods of pollination bagging-self-pollination, bud-pollination and open-pollination―in field conditions and calculated the self-compatibility index and relative compatibility index of 52 cultivars of E. sativa from China, Iran and Pakistan. Results showed that (1) E. sativa is a highly self-incompatible plant, but several cultivars may have self-compatibility genes; (2) E. sativa cultivars show variation in self-compatibility; the mean compatibility index ranged from 0 to 4.98, with variation among individual plants; (3) E. sativa cultivars could be divided into 4 groups: highly self-compatible, self-compatible, self-incompatible and highly self-incompatible; and (4) the self-compatibility varied by geographical origin in the order of southwest>northwest>North China.
