Abstract: | During 1998-2000, Bulgarian hybrids of a Chinese silkworm AC*Ukr. 20, KC*Ukr. 20, (AC*Vr. 35)*Mer. 2, (AC*Vr. 35)*(TB*Mer. 2) as well as their reciprocal crosses and Ukrainian hybrids Ukr. 27 PK*Ukr. 15, Vr. 52*Ukr. 18 and Mer. 6* Mer. 7 are studied in agricultural company «Agromier» (Cairo, Egypt.) It was found that the hybrids between AC*Ukr. 20, (AC*Vr. 35)*Mer. 2 as well as their reciprocal crosses have high biological parameters of the caterpillars and high technological properties of the row cocoons, as follows: silkworm egg reanimation, 96.67-97.33 %; viability of caterpillars, 87.33-90.75 %; raw cocoon output per box (20000+-200 viable silkworm eggs), 43.670-44.962 kg.; raw cocoon weight, 2396-2669 mg; weight of silk memrane, 603-645 mg; silk ratioof raw cocoons, 24,17-25,17 %. This hybrids (AC*Ukr. 20, (AC*Vr. 35)*Mer. 2) as well as their reciprocal crosses will be proposed for industrial use to all sericultural companies in Egypt. |
