| Abstract: | A satisfactory method has been developed for screening potato clones for field resistance to early ligbht. Differences in clonal resistance can be evaluated and have proven to be consistent. Resistance to foliar infection appears to be generally associated with plant maturity. Late maturing selections are generally quite resistant and early maturing selections are usually extremely susceptible. Differences in resistance among named varieties from throughout the world were extremely variable. |
