METHOD FOR DETERMINING POTATO RESISTANCE TO COLORADO BEETLE Russian patent published in 2000 - IPC

Abstract RU 2148905 C1

FIELD: agriculture, in particular, selection of kinds of potatoes for development of Colorado beetle resistant kinds of potato. SUBSTANCE: method involves direct evaluation of plant qualities responsible for its resistance by hydrolyzing potato leaf starch by Colorado beetle peptic ferment, as well as by determining concentration in potato leaves of physiologically active alkaloid-α-tomatine, which does not deteriorate nutritive qualities of potato tubers. The less potato leaf starch is hydrolyzed and the higher is the content of α-tomatine, the more resistant is potato plant of this kind to Colorado beetle. Method allows particular mechanism of potato resistance to Colorado beetle to be determined under laboratory conditions and purposeful selection of resistant kinds of potato plants to be performed. EFFECT: increased efficiency in selecting parasite resistant kinds of potatoes and improved nutritive and gustatory qualities of obtained tubers. 2 tbl, 1 ex
