Assessment of ecological stability and adaptive capacity of parsley agrocenoses

It has been established that genotypic effects are predominant in the creation of early and general yield of parsley. But the influence of the environment is also manifested, and the environment appears in the broad sense of the term. This should also include anthropogenic impacts on a particular genotype of parsley, which entails a change in the complex of genotype reactions to the dynamics of soil and climatic characteristics. In this connection, the assessment of the genotype by these properties makes it possible to more accurately predict its behavior in changing conditions. Evaluation of the genotypes of parsley varieties based on the early harvest of green leaves showed the advantage of Gloria and Breeze varieties (1,90 kg/m). They were also characterized by maximum values of general adaptive ability (0.26-0.35) and low values of specific adaptive ability. These varieties have the lowest variability in response to the use of growth regulators (the values of relative stability of genotypes were in the range of 0.005-0.007). The calculation of the breeding value of genotypes for these varieties showed high values (1,72-1,77). Evaluation of parsley genotypes by the total yield of green leaves showed the advantage of the varieties Gloria, Breeze and Obyknovennaya listovaya (3,59-3,78 kg/m). They were characterized by high values of the overall adaptive capacity (0,50-0,56). They were characterized by rather low rates of variability in response to the effects of growth regulators (the relative stability of genotypes was equal to 0,315-0,594). The highest breeding value of the genotype was obtained for the varieties Gloria, Breeze and Obyknovennaya listovaya (1,5551-2,5539).
