بررسی خاص سازی دو توده زنبور عسل در شهرستان نجف آباد

Queen as the mother has an important role in a hive and al1 the traits of the hive such as laying eggs, population fluctuations and growth, nectar collecting and bahavior depend on queen. Therefore, the experiment carried out to improve economical and production traits of queens. Samples were chosen randomly from two populations belong to queen rearing project of J ihad-e- Sazandegi of Isfahan, namely Iranian honey bee (Meda) and the population used in Isfahan. The traits of honey production, laying eggs, popuJation size and swarm were recorded monthly. Based on selection method, best colonies were chosen as father's and mother's colonies and required qeens were reared. The queens wen~ mated by drones :in an isolated station. Then, 52 colonies of two chosen populations (including yel10w and black queens)were studied in comparison with 29 control colonies. Within the study the hives colonies were also migrated to suitable areas where natural flow of nectar presented. The traits of laying eggs, population fluctuations, honey production and temperament also were recorded. Genetic purification of the populations lasted 2 years. The result showed the1t honey production varied ranged from 1.2 to 20 kg which showed no significant differences (P> O.05) with control (1.5 - 20). The average of honey production calculated 10.97 kg. It was concluded that purification of the populations I for the short time, of study has no signifjcant decrease in honey production. Since the diversity of genes has been enough and may be longer purification leads to a decrease in honey production.
