INFLUENCE OF FEEDING NORMS ON BIOLOGICAL INDICATORS AND ON THE PHENOTYPIC VARIABILITY OF MULBERRY SILKWORM UNDER THE CONDITIONS OF THE REPUBLIC OF AZERBAIJA
Abstract
In comparison with the normal conditions of feeding, in the conditions of abundant feeding, the mean values of the studied biological indicators (except for the silkiness of wet cocoons) are exaggerated, and phenotypic variability decreases. With poor feeding, the average values of the indicators decrease, and the phenotypic variability increases. During the study, the minimum increase and decrease of the average value of all symptoms and the coefficient of variation in the Mayak-3 breed were revealed; the greatest increase and decrease of indicators were marked in the Yashar breed; and in the Ganja-6 breed, growth and deposition of indicators were at an average level. Thus, the hereditary tolerance to the environmental impact of the feeding factor is strong in the Mayak-3 breed, moderate in the Ganja-6 breed, and weak in the Yashar breed.
