This article analyzes the productivity of cocoons and such main process parameters as the dry weight of cocoon output raw silk, the output of silk products from the dry cocoons, the cocoons unwinding properties, the total length of cocoon filament, continuous length of cocoon filament and cocoon metric number of the thread of simple and complex hybrids, created by scientists of Scientific research Institute of sericulture. The studies studied simple hybrids Musaffo Tola 1, Musaffo Tola 2, foreign hybrid Jing song Hoayou, as well as complex hybrids Uzbekistan 5 and Uzbekistan 6. As a result of studies on productive indicators, the complex hybrid Uzbekistan 6 in the spring season of 2018 showed a high mass of cocoons in comparison with others, 1.89 g, and in the next 2.35 g. in other hybrids, this indicator turned out to be relatively low. In terms of the mass of the cocoon shell, a simple hybrid Musaffo Tola 2 was identified in 2019. In addition, according to technological indicators, a simple hybrid Musaffo Tola 1 showed a high overall length, namely 1691 m. the unwinding of the thread in this hybrid is also greater than in other hybrids-91.1-92.6%. Engineering Science and Materials: Technology of cotton and textile industry 2 Textile Journal of Uzbekistan №2/2019 Complex hybrids Uzbekistan 5 and Uzbekistan 6 (1200-1508 m) distinguished themselves by the length of the continuously unwinding thread.
