Summary
This study was undertaken to determine whether the Are gene controlling anthracnose resistance had an adverse effect on maturity and yield because backcross-derived cultivars/lines had numerically lower yield and later maturity than the respective recurrent parent. Three pairs of common bean lines near-isogenic for theAre gene were developed fromAre are F2 plants of the sixth backcross of Seafarer, Fleetwood, and Ex Rico 23. The near-isogenic lines were tested along with the recurrent cultivars and backcross-derived cultivars/lines. The results showed no evidence of any adverse effect of theAre gene on the agronomic characteristics in 11 trails at 5 locations in 3 years.
