Abstract

Stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important fungal disease of wheat causing significant grain yeild and quality losses in many regions of the world. It has become a serious constraint to wheat production in Georgia in the past years. Growing resistant cultivars is the most effective method of disease control. The goal of this study was to determine levels of resistance in wheat species, old Georgian cultivars, breeding lines and introduced cultivars and to develop a panel of cultivars that can be utilized in future. The responses of fifty two wheat genotypes including wheat species, domestic landraces and introduced entries from different international nurseries to stripe rust Georgian population at seedlings and adult plant stages were studied. High level of juvenile and adult plant resistance to the disease was detected in nearly all tested species and subspecies. Three old domestic varieties Khulugo, Lagodekhis grzeltavtava and Tetri ipkli showed resi
