Annotation

The creation of resistant varieties to coccomycosis (one of the most harmful diseases of cherry and sweet cherry) corresponds to the strategic directions for the development of Krasnodar Territory No. 1: a cardinal improvement in the quality and longevity of the population. In this regard, an important role is played by providing the population with the high-quality environmentally friendly products. The creation of resistant varieties Will allow you to avoid or reduce the number of chemical sprayings, to reduce the fruit production costs, and the most importantly, to help in solving the problem of obtaining environmentally safe products. As a result of many years work on the creation of genotypes resistant to coccomycosis, the forms of 3-33-34 and Yuzhanka were selected to the elite, which, due to a number of economically valuable and adaptively significant traits, differ markedly from standard varieties. So, under the conditions of the Goryachy Klyuch district, where as a result of long-term monitoring, it is noted in the population the most virulent clones overcoming the resistance of the A gene, the full yield was obtained only from the elites of Yuzhanka and 3-33-34 on the rootstocks of the NCFSCHVW breeding � to 16 t / ha. They are differed on the lowest indicators: the average number of coccomycosis pustules per 1 cm2 of leaf (0.08 � 1.1 to 5.25 � 1.3), resistance index (0-1357), generative activity of the fungis (0-2629). Timiryazevskaya cherry are also selected to the elite, with the late development of coccomycosis. Its distinctive features � the original taste of the fruits, high yield, up to 100 kg per tree. These elite forms also showed the complex resistance to drought, high summer temperatures and a number of diseases, which proved their suitability for resource-saving technologies of gardening.
