Whole-genome sequences of 37 breeding line Bombyx mori strains and their phenotypes established since 1960s

Bombyx mori is a key insect in the sericulture industry and one of the very important economic animals that are responsible for not only the livelihood of many farmers internationally but also expended biomedical use. The National Institute of Agricultural Sciences of the Rural Development Administration of Korea (NIAS, RDA, Korea) has been collecting silkworm resources with various phenotypic traits from the 1960s and established breeding lines for using them as genetic resources. And these breeding line strains have been used to develop suitable F1 hybrid strains for specific use. In this study, we report the whole-genome sequences of 37 breeding line B. mori strains established over the past 60 years, along with the description of their phenotypic characteristics with photos of developmental stages. In addition, we report the example phenotypic characteristics of the F1-hybrid strain using these breeding line strains. We hope this data will be used as valuable resources to the related research community for studying B. mori and similar other insects.
