Selection of the Silkworm Bombyx mori L. Breeding Resource Material

Identifying Hybrid Genotypes of Mulberry Silkworm (Bombyx mori) Using Heterosis for Biological and Silk Yielding Traits

“…EI is relatively greater for silk yielding traits compared to biological traits. The present MEI values are broadly comparable with earlier reported by Bhat et al (2018); Sajgotra and Gupta (2018), and Alam et al (2020). Bhat et al (2018) reported MEI between 45.16 and 56.86 for 18 pure and hybrid strains.…”

Bhat et al (2018) reported MEI between 45.16 and 56.86 for 18 pure and hybrid strains. Sajgotra and Gupta reported MEI from 31.38 to 57.51 for ten bivoltine hybrids, while Alam and co-workers found MEI between 42.98 and 61.66.…”

Novel insights into the economic relevant phenotypes ofBombyx moristrains from Romanian breeding centres

“…This result might suggest a possible benefit when sample means are used, as large standard deviations in the populations result in overlapping of distribution tails, as can be observed from Figure 4 and the corresponding histograms (Supplementary Figure 1). In a study arguing the importance of breed selection for the success of any further enterprises, Bhat et al (2018) compared 18 silkworm breeds and found significant differences among the traits with economical relevance (Bhat et al, 2018). In our hands, KODAMA analysis also revealed the likely distinct group formed by GB and ACH.…”

“…Zanatta et al (2009) found noticeable differences between 16 Chinese or Japanese breeds regarding cocoon length, cocoon weight, raw silk percent and larval body weight (Zanatta et al, 2009). In addition, Bhat et al (2018) identified variability between 18 silkworm breeds for phenotypic traits such as fecundity, hatching percentage, survival percentage, single cocoon weight, single shell weight and silk filament length (Bhat et al, 2018). Results of this type suggest that certain biological traits are specific for particular B. mori breeds and selective breeding strategies can enhance desired traits.…”
