Abstract
Relevance. The creation of varieties and hybrids with environmental sustainability is a priority in crop breeding. Many issues related to biology and ecology of a number of spice plants remain understudied. The study of the biological and ecological characteristics of common dill in order to create straight varieties with high yields in the phase of industrial ripeness in our conditions has not been carried out. The aim of the research was to evaluate the parameters of adaptive capacity and ecological stability in collection samples of common dill in terms of yield.
Materials and methods. The research was carried out in the experimental field of the Department of Fruit and Vegetable Growing of the Belarusian State Agricultural Academy, Gorki, Mogilev region over a period of 2012–2014 and 2019–2021. The objects were breeding samples of common dill. Field and laboratory experiments were carried out using generally accepted methods and guidelines. The meteorological conditions during the years of the research differed both in terms of temperature indicators and the amount of precipitation, which contributed to an objective assessment of the varieties under study according to a complex of economically useful traits.
Results. The article presents the results of the study of common dill breeding samples obtained in different years of research. In the first set (2012-2014) there were 40 sample plants, in the second set (2019-2020) – 26 pieces. In the course of assessing the parameters of adaptive capacity and ecological stability, the diversity among the samples of common dill was revealed according to the main parameters. The difference in terms of yield between sets of genotypes and test conditions over the years indicates the relationship between the genotype and the environment. Based on the results of studying the common dill collection, the parent material for breeding for a consistently high yield was selected. The regularity of maintaining the stability of the trait "yield" with a repeated set of genotypes in different years of research has been established.
