The resistance of some cultivars of medicago sativa l. Against fungi genus fusarium link. Ex fr

Abstract

The resistance of seven cultivars of Medicago sativa L. against fungi of genus Fusarium has been investigated. In order to evaluate the resistance level we have used the method of plant inoculation on seven day old plants grown in the greenhouse. The intensity of disease was estimated on the basis of visual examination of plants. In the reaction of cultivars considerable variability was not observed. Among examined cultivars Zaječarska 83 cultivar was moderately sensitive, while the cultivars K22, K23, K28 Triade, NS Mediana ZMS V and NS Banat ZMS II expressed high sensitivity.

Ispitivana je otpornost sedam sorti Medicago sativa L. prema gljivama roda Fusarium. Za ocenu nivoa otpornosti korišćena je metoda inokulacije biljaka starih sedam nedelja koje su bile odgajene u uslovima staklenika. Intenzitet oboljenja ocenjen je na osnovu vizuelnog pregleda biljaka. U reakciji sorti nije se ispoljila znatna varijabilnost. Među ispitivanim sortama srednje osetljiva sorta je Zaječarska 83. Visoku osetljivost ispoljile su sorte K22 K23, K28, Triade, NS Mediana ZMS V i NS Banat ZMS II.
