Comparison of the Eggs and Cocoons Quality of Some Mulberry Silkworm Hybrid Bombyx mori L.

Sericulture is one of the non-timber forest products (NTFPs) that can help Indonesians live better lives and support environmental improvement. Silk, as a product sericulture, five NTFPs Indonesia has identified having ability to boost nation’s economy alleviate poverty. However, there are several issues with development silk in Indonesia, chiefly quality silkworm seedlings low cocoon yield. Crossbreeding method used egg output. This study aimed evaluate eggs cocoons produced by various (Bombyx mori L.) crosses. The Pustarhut Laboratory hosted research from May August 2022. Twelve treatments were employed form crosses using Randomized Block Design (RBD) method, each treatment applied three replicates. Overall, findings demonstrated CE cross ((919 x 927) (804 p208)) (652 eggs) higher than other crossings. although numbers CF × (p208 804)) FC ((p208 804) (919 927)) 622 631 eggs, respectively significantly different cross, they still above 600. In addition, was not cross. All finding indicates silkworms CE, CF, be an alternative superior breeding increase productivity rearing Indonesia. Keywords: Bombyx mori, quality, double-cross, seed
