Queen breeding and genetics e-bog

Breeders and producers of queens need a handbook which describes the background of their work. It can only be done if ou know the techniques of rearing queens and judging the results. You must know the genetics of the bees, too, because it enables you to plan the maintenance and improvements of your stock. The aim of this book is to help the practical people who rear queens. The author has written books and articles of beekeeping since 1983, see www.eigilholm.dk.
