This article examines the history of silkworm breeding, the role of silkworm breeding in the national economy of the Republic of Uzbekistan and the role of silkworm breeding in the development of the industry. This is because the interrelationship of traits of economic value is of great importance in selection and breeding work. The experiments were conducted in 2015-2017 at the Silk Research Institute of Uzbekistan. The life expectancy of the experimental butterflies was 10.9-12.8 days and the variability was 33.9-56.6%. The coefficient of variability indicates the degree of diversity in the population on this trait. Thus, it is clear from the results that the population of “Marvarid” and “Liniya 27” has the ability to carry out selection work on the sign of life expectancy of female butterflies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
