Antonenko O. Diseases of Winter and spring rape, measures resistance rice of varieties and hybrids

The scientific statements of dissertation are presented in 22 scientific papers and are defended by 12 copyrigth certificates. They are the researches of most widespread diseases and their damages. Losses in seeds yield depending on the development intensity of some diseases can reach from 10 to 80% and more. Powdery mildew and clubroot are found on raps for the first tivt and their harmfulness was studied. Biological peculiarities of most distributed diseases (sources of infection,types of sporulation, influence of weather conditions etc.) are precised. Infection loading of diseases and their use by the estimation of sorts and outgoing material are studied. Scales for estimation of selection material fnd raps sorts on their resistance to diseases and their use on sorts'areas of government selection are created. Methods of mass, individual - familiar selection, adaptive selection and their use by creation of resistant to diseases sotts are developed. Guarantee of success was development of complex program for the selection of new raps sorts with enhanced resistance to diseases, igtroduction in production and recommendations of technology of their growing. Appliend aspects of created raps sorts were studied: gualitative characteristics of plant oil and nutrient value of green mass for animals. Agrotechnical and chemical protection remedies for raps against diseases are recommended, which are the part of technology for raps sorts growing.
