- | Bs2 was the first cloned resistance gene in pepper (Tai //et al.//, 1999). Bs2 was backcrossed over 7 generations into the commercial pepper cultivar Early Calwonder (ECW) to produce a near-isogenic pepper cultigen (ECW20R) (Stall //et al//., 2009). The three resistance genes //Bs1//, //Bs2//, and //Bs3// were transferred to a single plant of ECW and designated ECW123. | + | //Bs2// was the first cloned resistance gene in pepper (Tai //et al.//, 1999). |
