Abstract
In the first direction of this article, the new Marhamat, Mustaqillik-18 and Jararik-12 varieties of mulberry have economic value characteristics, such as leaf stem size, leaf length, leaf width, leaf stem length, leaf weight, leaf stem weight, leaf stem weight, and net leaf weight. In addition, the systems of mulberry silkworms Liniya-101 and Liniya-205 were cultivated with Marhamat, Jararik-12 and Mustaqillik-18 and Tajik seedless varieties of mulberry. The second direction of the study was the experiments on in vitro propagation of new varieties of tobacco, and the cost-effectiveness of testing in the conditions of production of positive data obtained on the basis of the results of 2017-2020. At the same time, it can be seen that the economic efficiency of mulberry varieties grown and introduced in vitro is 4,695,300 UZS, net profit is 1,577,500 UZS, and the size of profitability is 39.6% contrast to the comparator.
Highlights
Today, live silk cocoon raw materials are produced in more than 20 countries around the world, as well as mulberry fruit is grown in more than a hundred countries for woodworking, landscaping, landscape design, medicine and mainly for the large-scale mulberry silkworm food base [1, 2]
The People's Republic of China accounts for 82.1% of the silk production, India for 16.1%, Uzbekistan for 0.6%, Thailand for 0.4%, Brazil for 0.3%, and other silk-producing countries for the remaining 0.5%
It is important to create new high-yielding varieties and hybrids of mulberry belonging to the genus Morus alba L., as well as to increase the cocoon productivity of silkworm hybrids by creating new mulberries [6]
Summary
Live silk cocoon raw materials are produced in more than 20 countries around the world, as well as mulberry fruit is grown in more than a hundred countries for woodworking, landscaping, landscape design, medicine and mainly for the large-scale mulberry silkworm food base [1, 2]. Mulberry is cultivated on 626,000 hectares in the People's Republic of China, 280,000 hectares in India, and more than 35,000 hectares in Thailand and Brazil. 85-90% of mulberry seedlings are propagated vegetatively in the People's Republic of China, 75-80% in India, 98% in Japan, and 4-5% in Uzbekistan [3, 4]. The People's Republic of China accounts for 82.1% of the silk production, India for 16.1%, Uzbekistan for 0.6%, Thailand for 0.4%, Brazil for 0.3%, and other silk-producing countries for the remaining 0.5%. It is important to create new high-yielding varieties and hybrids of mulberry belonging to the genus Morus alba L., as well as to increase the cocoon productivity of silkworm hybrids by creating new mulberries [6]
