Study of inbreeding in apiaries of Miyaneh region, Iran

Inbreeding causes harmful effects on different characteristics of honey bee colonies such as honey production. In order to study of inbreeding rate in apiaries of Miyaneh region, %5 of modern hives were choosed and scales and standard Langerstrot combs were used according to Rotner method. Bee population was recorded and free of brood cells were considered as inbreeding index. Honey production was also measured by weighting the hives. inbreeding rate was estimated as 5.05%. results showed that there were no significant differences between inbreeding rate of several bee populations in Miyaneh region. Inbreeding percent was 9.%, 0.9% and. 48% for Kandowan, Torkmanchai and Kaghazkonan areas, respectively. Mean honey production per hive was also. 9 kg. According to this study there were significant negative relationship between inbreeding and honey production (r = -0.57, P= 0.09) in apiaries of Miyaneh region of Iran.
