Breeding of strawberries in water where other fish would freeze to death but, with a special gene that allows it to produce a sort of anti-freeze, it can survive. This gene is put into a bacteria that is sprayed on the strawberry during the freezing temperatures, allowing it to also be resistant to cold. The strawberry is then cleaned, removing the bacteria. Breeding of strawberries The breeding of strawberries is a long story that starts with the selection and cultivation of European strawberry species in western Europe in the 15th century while a similar discovery and cultivation occurred in Chile. The most commonly
Tree breeding disease-resistance, wood properties, etc. Currently, tree breeding starting to take advantage of the fast development in plant genetics and genomics. Tree breeders make efforts to get their operation efficient by optimising tree breeding. Scientists develop tools aimed at improvement of the efficiency of tree breeding programmes. Optimising can mean adapting strategies and methods to certain species, group of populations, structure of genetic variation and mode of inheritance of the important traits to obtain the highest benefit per unit of time. Optimising is usually carried out at the following levels: breeding strategy (appropriate intensity of breeding, breeding population structure and size,
