Iron deficiency Chlorosis in peppers

A yellow‐fruited inbred pepper cv. ‘Zehavi’, was found to be highly chlorotic on a previously non‐cultivated calcareous soil in the Arava Valley (Israel) during winter 1981–1982. Foliage symptoms and a test for diagnosing iron indicated iron deficiency, soil application of Fe EDTA corrected the symptoms in the field. When ‘Zehavi’ was sown at the same location, in the winter of 1982–1983, but on calcareous soil which had previously been cultivated for several years, no chlorosis appeared. Inheritance studies indicated recessive control for iron deficiency chlorosis but complete genetic interpretation is suggested only under controlled iron deficiency conditions.
