Аннотация

Subjects of research: silkworm. Purpose of work:: creation and selection of breeds and hybrids of silkworm steady for summer and autumn season conditions, intended to multiply for rebreeding. Methods of research: analytical and synthetic methods of selection. The results obtained and their novelty: new breeds УзНИИШ 9 and АГУ 112, and hybrids with their participation УзНИИШ 9 x АГУ 112 and АГУ 112 x УзНИИШ 9 were brought-up, as well as were selected industrial hybrids with the participation of breeds marked by the gender, adapted for the unfavourable conditions of summer and autumn worm-breeding. New kinds of silk-trees were revealed, which promoted to the productivity of breed-hybrids in rc-brccding. Practical value: New brought-up breeds and hybrids УзНИИШ 9 x АГУ 112 and АГУ 112 x УзНИИШ 9 will be reproduce and multiplicatcd in the conditions of summer and autumn seasons, and by this way will increase the volume of silkcocoons in the republic. Degree of embed and economic effectivity: new and selected hybrids, intended to re-breed, will be multiplied in the silkworm producing factories of the republic after they arc examined by the state experiments and tests. The economic effectivity of the work will be expressed by the volume of the silk-cocoons harvest in re-breeding. Field of application: silk production studies of science, stations of silkworm pedigree, and silkworm producing factories.
