Selection of partenogenetic clones for mixing with fine silkworm breeds in the conditions of Uzbekistan

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