Resumen:
The phytochemical-resistance trait comprises of is one or more compounds produced by the crop for resistance against pests and diseases. Breeding for phytochemical resistance-traits may offer more stable crop resistance and less dependance on pesicides.. Nevertheless, incorporation of phytochemical resistance-traits in crop improvement faces several problems viz., monitoring during breeding process and their biological impact on agroecosystems. This Paper describes several methods for easy monitoring of phytochemical resistance-traits in crop species, including the rapid and often cheap assays to measure contents of glucosinolates, cyanogenic glycosides, phenylpropanoids, alkylresorcinols, resveratrol, salicylic acid and activity of phenylalanine ammonia-lyase. These methods should be used complementary to visual traits of resistance such as ratings of disease, or insect feeding. They can provide a better understanding of the underlying mechanisms involved in crop defense to pests and diseases.
