Abstract:
To determine the inheritance of resistance in Redlan, a F2 population was developed and evaluated at the USDA-ARS Tropical Agriculture Research Station in Isabela, Puerto Rico in 2005. Results of the disease evaluation indicated that foliar anthracnose resistance observed in Redlan is controlled by a single dominant gene. Anthracnose infection of the leaf midrib was also observed in the F2 population and results indicate resistance for midrib infection is controlled by a single recessive gene. Segregation analysis, based on the frequency of recombinants for foliar and midrib resistance, indicated that the two genes are unlinked.
