TESTING OF SOME RACES FROM GENE-BANK OF SILKWORM (BOMBYX MORI I.) POPULATIONS, ITRODUCED FROM DIFFERENT ECOLOGIC-GEOGRAPHICAL ZONES. III. RACES WITH GEORGEAN, SYRIAN AND VIATNAMESE ORIGIN

摘要

Testing of six races from National gene-bank of silkworm populations, introduced from Georgia, Syria and Vietnam was done. Testing was made through the subordinate function (SFi) and evaluation indices (Ei) methods and race ranking was done by total cumulative indices (TCi) method. It was established that used statistical methods for testing of introduced from Georgia, Syria and Vietnam races by subordinate function and evaluation indices permit to identify and use the best of them together with perspective Bulgarian races for selection of new synthetic populations and for industrial hybridization. Syria_2 and Syrian_1 Syrian races and Mziuri_2 from Georgia had approximately the highest merits for Bulgarian ecologic-geographical conditions. Syria_2and Syria_1 will be used in selection program as donor, vector, of genetic plasma for increasing of pupation rate character and for industrial hybridization with perspective Bulgarian races.
