A COMPARISON BETWEEN A DETACHED LEAF AND A WHOLE PLANT METHOD FOR SCREENING PHYTOPHTHORA FOLIAR BLIGHT RESISTANCE IN CHILE (Capsicum annuum)

摘要

A key focus in many chile breeding programs is the development of cultivars resistant to Phytophthora foliar blight (Phytophthora capsici) has become a key focus in chile breeding programs. A detached leaf technique that reflects the whole plant genotype could reduce the assay time from 7-12 days to 3 days and require only a leaf instead of the whole plant. A detached leaf method was compared to the whole plant method, which is the common standard for screening foliar blight resistance in Capsicum. The detached leaf method could not produce results matching the existing whole plant screening method. Therefore, the detached leaf method may not be a suitable way to screen for foliar blight resistance in Capsicum.
