“…Monovoltine groups with a diploid set of Chromosome equal to 56 are the most productive breeds, and these breeds and systems serve as initial selection materials for the creation of new fertile and moc canoat breeds and hybrids of mulberry silkworm for different regions. At the same time, the creation of new systems, breeds and hybrids with high viability and cocoon productivity of mulberry silkworms, which are resistant to various ctrecc conditions and meet the high requirements of canoe sericulture, remains one of the important tasks [2].…”

“…In the mulberry silkworm breeder, selection camaraderie is largely positive, because economically valuable characters are positively correlated with other selection characters, and as a result of selection, the indicator of the second character increases, as well as the relationship is in a negative or negative direction, and it is known in advance that the indicator of the second character decreases [2]. In this regard, the authors thoroughly studied the phenotypic correlation of various selection traits of agricultural animals in their scientific works and gave their conclusions by illuminating the analysis in a comparative manner.…”

Agriculture plays a key role in the economy of Uzbekistan. Its importance is not limited to the goals of providing food to the population. This is reflected in the cultural heritage and traditions of the people of Uzbekistan in rural areas, in each region of Uzbekistan with its own characteristics and diversity. Today, agriculture in Uzbekistan in general, including cocooning, provides jobs and income to a significant part of the population and remains the driving force of the growth of the economy of Uzbekistan. At the same time, as the economy of Uzbekistan is gradually diversifying, this means that the agrarian sector and the cocooning sector must also be radically reformed, which encourages them to look for new opportunities for competitiveness and sustainable development in the domestic and foreign markets. This requires a new approach to the development of the industry. This article discusses the importance of the role of cocooning in the agricultural sector in the national economy, the strategy for the development of Uzbekistan’s agriculture for 2020-2030, selection and breeding in the development of cocooning, and the role of seed production. In addition, in 2018-2020, the results of the study of the correlation between the life span of butterflies and the valuable traits of their offspring at the Research Institute of Sericulture were cited. The use of the results in science and production practice, as well as the expected results, that is, increasing the quantity of cocoons produced, improving the quality and increasing the competitiveness, are highlighted by the authors.

“…Monovoltin breeds and systems of mulberry silkworm Bombyx mori L are cultivated in more than 20 countries around the world [1]. According to the International Silk Commission (INSERCO), in countries where silkworm science is developed, such as China and India, special attention is paid to the creation of fine-fiber breeds and hybrids that are adapted to different climatic conditions and meet the requirements of silk fiber categories 3A and 4A [2,3]. The creation of high-quality and industrial hybrids of fiber that meet the requirements of the world silk market and the silk industry, as well as the improvement of genetics and selection processes of mulberry silkworms is of great scientific and practical importance [4].…”

The creation and introduction into production of new breeds and hybrids that meet the needs of the world market and industrial enterprises through the development of selection methods for breeding stations and seed enterprises is of great scientific and practical importance. In this regard, the work of a number of local and international scientists is devoted to the selection and creation of new breeds and hybrids of mulberry silkworm on the basis of leading selection traits. The effectiveness of the artificial parthenogenesis method developed in our laboratory is that the effect applied suppresses the reduction division of egg cells. Also, the parthenogenetic genus immediately receives the same set of chromosomes and genes. However, ♀ clone × ♂ hybrid worms have a high viability, the cocoons are the same in shape and other characteristics, there is no work on the separation of the primary parent breed (parthenoclonus) for hybridization (because it consists of 100% only females), breeding at all stages work is not done (because all parthenoclon females are genetically the same and do not change by generation). It is also possible to obtain all the cocoons of parthenoclon in the extraction of cocoons, as their genetic homogeneity completely eliminates the sorting of cocoons in breeding stations and seed plants.

According to the history of sericulture, the domestication and utilization of the silkworm as a source of silk began in the Shang-tung province of China around 3000 BC, and silk weaving began 2700 BC. Only intimate members of the imperial family and women of high birth were allowed to work in the manufacture of cocoons and silk in ancient China, which was considered to be nearly holy. From ancient times, the Chinese have rigorously controlled the breeding of silkworms and the monopoly of silk, safeguarding the lucrative business with regulations that make it illegal to receive raw silk, disclose methods for producing cocoons, or even have the desire to export silk. This article deals with sericulture in general, its grain production, the role of papillonage in pedigree sericulture stations, where pre-breeding grain is prepared, super-elite and elite, in grain factories where hybrid or industrial grain is prepared for the production of industrial windows in farms and other farms.
