I am in the fourth year of a breeding program. I am already seeing great results, but have a question. I have been getting my virgins mated in the various yards I am running. I have the option of starting a new yard in the mountains in an isolated area. Drone colonies would be placed there, and my mating nucs would be brought in. I am selecting for wintering ability, honey production, and resistance to chalkbrood. My question. Is this necessary, or even warranted? It means a 100 mile trip. Maybe worth it if the results are there. But, will I be leaving genetic material behind? In the short run perhaps an isolated yard would be best, but I have a feeling that if I saturate my area with good stock, I would get good results. In the long run, would this not be a better approach? Mike
