Comparative stability analysis of the hybrid “Mizuri-5 x Mayak-6” to adverse environtental conditions of high productivity in adaptive breeding for the development of sericulture

Abstract

Relevance. In Azerbaijan, the roots of sericulture lead to ancient times. The problem of obtaining new silkworm hybrids capable of adapting most quickly to adverse agroclimatic factors while maintaining high productivity is very relevant at the present stage of development of the agricultural sector of Azerbaijan.

Methods. The purpose of the study is to create silkworm hybrids Nesa2\1 x Khayal and Mizuri-5 x Mayak-6, which are superion in adaptability and resistant to agroclimate and seasoned feeding (spring, summer, autumn). The studies were developed by the parameters of integratedassessment and adaptive selection.

Results. Accerding to environmental parameters, the arerge ectimate of the stability constant and the selection index, comparable indicators of the Mizuri-5 x Mayak-6 are quite high. using the method of adaotive selection and integrated assessment, the results of our research give us grounds to assert that the Mizuri-5 x Mayak-6 hybrids adapt even to favorable conditions and very tolerant seasoning. Ultimately, the viability of the silkworm has a value of 10% moisture, 20% temperature and 70% mulberry, which is the only food for the silkworm caterpillars, and with changes of this agroclimate, the silkworms functional indicators change. Thus, the new hybrids we have created are resistant to the fluctuations of agrocilimate and correlate to any seasonal feed.
