Sažetak
Alfalfa and red clover are the most researched perennial crops in major forage legumes breeding programs. Agronomical interests for these crops are based on its numerous advantageous characteristics such as high yield potential, suitable feeding value and favourable environmental impact. Perennial forage legumes breeding programs are usually based on mass selection, phenotypic recurrent selection and synthetic development using polycross method. The main objective of most breeding programs is the development of new varieties with high forage yield and quality and multiple disease resistances. Breeding program of perennial forage crops at the Agricultural Institute Osijek is existing and is continuously carried out for over than 50 years. In this period, the Institute has inscribed 19 varieties of alfalfa and two varieties of red clover and has as well a rich collection of genetic variability and diversity of domestic and introduced germplasm. Development of new varieties is a very long-lasting and difficult process where in the first place all the available germplasm needs to be evaluated, by means of large number of individual plants/cuttings in breeding nurseries over multiple years. In the each of several cycles of selection, the superior plants are selected and intercrossed, to generate new populations with improved important agronomic traits. In the climatic conditions of Republic of Croatia the major alfalfa and red clover diseases are Sclerotinia crown and stem rot, Verticillium wilt, Fusarium wilt, Common leaf spot, Downy mildew and Powdery mildew. In our breeding program we are selecting alfalfa and red clover plants carrying natural resistance to the major pathogens occurring naturally in the field. These resistant plants are the basis for the development of new varieties. In sustainable plant production systems forage crops have an important place due to numerous agricultural and environmental benefits.
