Uji Adaptasi Hybrid Ulat Sutra asal Tiongkok (Adaptation Test of Hybrid Silkworm from China)

Abstract

One of the factors that determine the success of the natural silk development in Indonesia is the supply of superior silkworm eggs. It can be done through the procurement of superior eggs both from domestic and imported. Superior silkworm eggs must have high quality and productivity. This study aims to examine the productivity and quality of hybrid silkworm eggs of the Liangguang II originating from China with the commercial local hybrid C301 and other commercial hybrids. The study was conducted at the Natural Silk Development Station, Garut Regency, West Java. The results showed that the Liangguang II hybrid had better larva quality than the local commercial hybrid C301. The Liangguang II hybrid had a shorter larval period of 1 day 2 hours, better cocoon quality, higher cocoon quality, and the same filament quality as the C301 hybrid. The Liangguang II hybrid had a higher percentage of cocoon shells (22.19%) compared to imported F9X7 hybrids from China (20.96%) and Bulgarian hybrids (19.26%). The Liangguang II hybrid is recommended to be developed in the highlands in West Java.

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

“…The conditions could contribute to the silk industry's ability to obtain high cocoon output and seeds of the necessary quality (Andadari 2016;Santoso 2012). The silkworm hybrid of C301 (Andadari and Kuntadi 2014;Minarningsih et al 2021), BS 09 (Estetika and Endrawati 2018), PS 01 (Agustarini et al 2020;Fambayun et al 2022;Yuniati et al 2021) are several types of hybrid silkworms from crosses are applied in Indonesia. This hybrid type crosses the existing Chinese and Japanese races.…”
