Productivity of Certain Varieties of Apples and Importance of Their Gene Formation

Due to the diversity of its natural and historical conditions, Azerbaijan is one of the centers of the initial formation of many plants, having a great genetic richness of the plant world. A large number of valuable varieties and forms of food and agricultural plants have been created through folk selection and scientific selection, with the history of agriculture covering several millennia. However, massive and anthropogenic disturbances of all these natural and cultural heritage ecosystems, which are the irreplaceable wealth of the people, created a large number of valuable varieties and forms of ecological and agricultural plants. However, all this natural and cultural heritage, which is the irreplaceable wealth of the people, is threatened with destruction as a result of mass and anthropogenic disturbances of ecosystems, ecological and agricultural changes, and the wide application of modern breeding achievements. In addition to all this, the study, protection, and effective use of the gene pool of the apple plant in the country is one of the main factors. In this regard, based on our long-term research, with the efficient use of the gene pool of the apple plant in Azerbaijan, new “spur”-type selection varieties (Nigar, Ziya, Zirva, Marfa, Sulh, Gobustan, Zumrud, Kyzyld Taj, Khazar, Eldar, Ulvi, Nübar, Vatan, Makhmari, Nuran, Sarvan, Chiraggala, Davamli, Emil, Elvin, Paizliq Guba, Zizliq Guba, Shabran, Sadaf and Sevinj) were created by us. In the article, the parental pairs of those cultivars are reflected in the ripening period, ripening, fruiting periods, tree parameters (height, diameter of the umbel, circumference of the stem), productivity indicators, leaf surface, infection rates of scab disease, average mass of fruits and tasting prices. At the same time, the article contains the introduction, research conditions, methodology, material, results, discussion, recommendations, and used literature sources.
