Effect of initial material creation methods on seed potato yield and crop structure

Abstract

This article presents the results of the research conducted for the purpose of studying the influence of the methods of initial material creation on seed potato productivity and crop structure. Also, the article provides valuable information about the influence of the methods of creating the initial material on the yield indicators of potato varieties. The results obtained in our research show that the methods of selection and initial material creation serve as one of the main factors determining the yield of clones. Based only on the visual method, the highest yield (26.6 t/ha) was obtained in the “Surkhan-1” variety. In the variety “Sante” this indicator was 23.0 t/ha, and in the variety “Umid 2” it was 24.7 t/ha. In the variant carried out with serological analyzes of this method, these indicators were 28.6, 24.6 and 26.3 t/ha, respectively, that is, the difference between the yield of the varieties according to the variants is 1.6-2.0 t per hectare. The highest additional yield was obtained from the variety “Surkhan-1” (2.0 t/ha).
