ABSTRACT
During six generations it has been studied a total of 30 inbred lines of silkworm
pursuing the effect of inbreeding on some biochemical parameters. The amount of
protein of silkworm eggs on the whole experience was in I3 (3rd generation of
inbreeding) between 11.91 % -14.20% and in I6 (6th generation inbreeding) between 12.22-14.62%, not influenced by the process of inbreeding. Some quantitative differences were correlated with the studied stage of embryonic development. The amount of lipids in silkworm eggs was in I3 between 80.6-98.8 mg/g eggs, ranging from embryogenesis stage, and 82.2-97.3 mg/g eggs I6, being influenced by the same factor. Inbred lines in both generations of inbreeding shows higher values of the control batch, but also do not show differences in statistical significance. In I6 the amount of fat shows the differences in less compared to I3, but these are insignificant. Biosynthesis of amino acids from sericine gland and from larvae hemolymph was not influenced by practice related type crossings brother x sister. In all samples was revealed a total of 18 amino acids and quantitative differences between samples, in general, insignificant were not correlated with inbred or not inbred character of silkworm lines. Determined silk fibroin content in I3 was within 73.16-77.18% for the lines group Baneasa White and between 71.16-75.86 % for the group lines Baneasa 75. Same component presented in I6 values between 73.20-76.90% for the first group of lines that are found significant differences against control batch and between 72.10-76.21% for the second group. Silk sericine contains was not affected by inbreeding depression. This presented to the group of lines Baneasa White an average value 24.24% in I3 and 24.57% in I6, being higher in the second group of lines, Baneasa 75, respectively 26.50% in I3 and 26.40% in I6.
