For the study, mulberry silk was used for different feeding seasons (spring, summer, autumn) and adverse environmental conditions (high temperature, low humidity, poor quality feed) using Atlas-1 and Atlas-2 lines. During the study, we calculated the selection and genetic parameters (selection variance (SD), genetic growth (R) and realized heritability (h2R) ratios) of the leading adaptive selection traits in successive generations of the Atlas-1 and Atlas-2 lines. As a result, compared to the line control population, the Atlas 1 line had a higher rate than the Atlas 2 line for the selection variance. Genetic growth was higher in F7 and F8 than the F6 lineage of the Atlas 1 line. The satin 2 line was the lowest in F7 and the highest in F7 and F8 generations. The biological parameters of both lines have a high barometric mass due to the hereditary coefficient, the barrel curtain mass is moderate, and the survival barrel silence is even lower. Generally, both lines have the ability to be inherited by biological indicators. The results from our selection experiments confirmed our theoretical provisions and made it clear that adaptive breeding carried out under pessimistic feeding of all generations would be beneficial.
