Our breeding work is aimed at creating varieties of this type. The paper presents the results of the long-term research on assessment of soybean varieties by their adaptability under different soil and climatic conditions by the yield, duration of the growing season and reproductive periods. The stability and plasticity of the researched varieties was determined using the Ebergard and Russell method. According to the research results, Artemida, Hoverla and Amethyst varieties were classified as highly plastic (bi>1) by the yield and they provided the yields of 1.95, 2.2 and 2.1 t/ha. In terms of duration of the growing season (BBCH-10-99), Amethyst, Hoverla, Artemida and Vezha provided high adaptability. These varieties were characterized by the conservative reaction to the change in hydrothermal and soil conditions ensuring stable indicators by the duration of the growing season (BBCH-10-99), coefficient of pasticity (bi) was under 1. The longest flowering-maturation period (BBCH-60-99) was observed in the following varieties: Amethyst – 69.1, Hoverla – 69.0, and Artemida – 69.1 days. The flowering-maturation period (BBCH-60-99) was under one. By the duration of the flowering-maturation period (BBCH-60-99), Amethyst, Hoverla, and Artemida varieties had the highest values of homeostaticity (Hom1 and Hom2), in particular, they were 32.8, 3.64 in Artemida, 30.2, 3.76 in Amethyst, 27.15 and 3.02 in Hoverla varieties.","PeriodicalId":39800,"journal":{"name":"测绘学报","volume":"26 4","pages":"398-411"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acta.fapz.uniag.sk/journal/article/download/154/113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
