Abstract


The analyze of some Bombyx mori L. (mono, tri and tetra) hybrids concerning five productive parameters weight of crude cocoon, weight of silk incartment, silk percent in cocoon, weight of dry cocoon and length of the silk wire is presented in this paper. In the end of the research the most valuable hybrids from production point of view could be identified. They can be reared in industrial system. The best results were obtained with monohybrids: B1x AC29, ABx AC and AC29x B1; trihybrids: ACx (ABx B1), (ABx B1)x AC and (ACx AC29)x B1 and tetrahybrids: (B75x AC29)x (B1x J90); (B1x J90)x (B75x AC29) and (ABx B1)x (ACx AC29). They were superior compared to other studied hybrids and we recommend these hybrid structures to be reared in both familial and industrial system.
