REPRODUCTIVE INDICATORS OF INDUSTRIAL HYBRIDS INVOLVED IN GENDER-REGULATED LINES OF BOMBYX MORI L. SILKWORM
Abstract
<strong>Abstract</strong>: <em>This article </em><em>reveals the </em><em>analy</em><em>sis of</em><em> the biological </em><em>indicators</em><em> of industrial hybrids </em><em>belonging to </em><em>silkworm</em><em> species</em><em> Bombyx mori L</em><em>. and obtained by involving</em><em> new </em><em>lines L</em><em>ine 5 </em><em>labeled</em><em>, </em><em>L</em><em>ine 6 </em><em>labeled</em><em>, </em><em>L</em><em>ine 31 </em><em>labeled</em><em> and </em><em>L</em><em>ine 32 </em><em>labeled on the color of egg</em> <em>and </em><em>created at Uzbek</em><em>istan</em><em> S</em><em>cientific</em><em> Research Institute</em><em> of Sericulture</em><em>. Due to the easy separation of one component of the hybrids into the sex, it is possible to reduce the cost</em><em>s</em><em> of </em><em>egg </em><em>production in the </em><em>silkworm </em><em>egg-producing</em><em> plant by 50%. In addition, the </em><em>combinations</em><em> involved in hybridization allow the production of full industrial hybrids with cocoon productivity.</em> <em>As a result of three years of comparative testing, ♀ Line 32 </em><em>lab.</em><em> x ♂ Line 101 and ♀ Line 101 x ♂ Line 32 </em><em>lab. combinations</em><em> showed positive results. When the cocoon yield from 1 box of </em><em>silkworm</em><em> was 76.6 kg in a foreign hybrid, ♀ Line 32 </em><em>lab.</em><em> x ♂ Line 101 and ♀ Line 101 x ♂ Line 32 </em><em>lab.</em><em> hybrids </em><em>produced</em><em> 85.9 kg and 92.5 kg</em><em> yield</em><em>, respectively.</em>
