Abstract
Selecting the suitable silkworm, Bombyx mori L. hybrids, for
rearing and highest productivity is the first step for increasing the
commercial production. Twenty silkworm double hybrids obtained from the
hybridization system of the sericulture research department were selected to
evaluate. In addition, an imported hybrid from Bulgaria was used as a check
parent. There were hy1, hy2, hy3, hy4,
hy5, hy6, hy7, hy8, hy9,
hy10, hy11, hy12, hy13, hy14,
hy15, hy16, hy17, hy18, hy19,
hy20, and the hyB (Bulgarian imported hybrid as check parent
hybrid). Fourteen economic traits were tested: fifth and whole duration of
larva, percentage of mortality, double cocooning percentage, cocooning %,
pupation rate, and cocoon numbers per liter were registered. Cocoon weight,
cocoon shell weight, weight of pupa, shell ratio, silk productivity, crop by
number, and crop by weight. Data reveal that there is no hybrid acquired the
better outcome for all traits together. Generally, hy13 and hy9
hybrids have superior data of eleven traits to gather. Whilst, hybrids of hy6,
hy14, and hy17 have good averages for nine traits
together. Also, hybrids of hy7, hy11, and hy18
have good averages over the check parent value for eight traits together.
