Abstract:

Cabbage is a group of vegetables produced in Turkey and worldwide. Cold disease comes at the forefront of diseases that cause economic losses in cabbage production. Today, there are no studies on the varieties that are resistant to the potosphaera xanthii and Golovinomyces cichoracearum species. The objective of this study is to reveal the genetic resistance of the various grapes that grow between the Western Mediterranean and the Eastern Mediterranean, such as local, wild and commercial water crabs, acur, crabs, crabs, crabs, honey crabs. The study caused the loss of productivity in cracks, the fertilizer pathogens Podosphaera xanthii and Golovinomyces cichoracearum species have been cultivated on the sensitive cracks species (Baccara). Morphological, microscopic and molecular studies on the cultivated saturation resulted in the pathogen Podosphaera xanthii. A total of 34 local, wild and commercial species of grapes inoculated with the patient P. xanthi were studied in the microscope for the first 3 days after the inoculation with trypan blue, diamino benzidine and 3,3'-dihexyloxacarbocynine iodide (DiOC6) coloring methods. In the following 7, 14 and 21 days, the development of the disease on plants was scored and resistant and sensitive spots were found. As a result of the pathogenic tests made, VT18, Meltem F1, Poyraz F1 and 348 commercial species and local species of Adana grapes, Kaledran grapes 1 and Kaledran grapes 2 were found as the most resistant grapes. In the study, 2 local species of Kaledran kavun. It is identified as the most sensitive plant to xanthii. In the studies, local, wild and commercial genotypes that are resistant to saturated P. xanthii will be able to be used as a resilience source for future healing studies.
