BIOLOGICAL INDICATORS OF SHELPOVICH HYBRIDS ON FEEDING WITH PROMISING SHULBERRY SORADS IN SPRING IN KARAKALPAKSTAN

Abstract

In this article, promising mulberry cultivars and silkworm hybrids were cultivated and their biological indicators were studied. From the obtained results, it can be seen that among the biological indicators of the variants, among the silkworm hybrids fed with the Jarariq-5 mulberry variety, Gozal x Marvarid (Oltin vodiy-2) 96,0 % was observed in option 3 of table 1. Table 1 option 3, which has the lowest incidence rate, is 2.63%. Among the hybrids of silkworm fed with Saniish-33 mulberry variety, the highest viability was observed in Ipakchi-2 x Ipakchi-1 hybrid, 95.6% in variant 2 of table 2. The lowest indicator of the percentage of disease 2.73% was observed in option 1 of table 2. In the conducted experiments, positive results were obtained and it was proved that the biological indicators of mulberry silkworm hybrids fed with promising mulberry varieties have better indicators compared to hybrids fed with Khasaki mulberry variety.
