Interpretive Summary: At the US Department of Agriculture (USDA) National Clonal Germplasm Repository (NCGR), we preserve temperate specialty crops and their wild relatives. We are VERY interested in keeping correctly identified cultivars of our crops and their wild relatives, including blackberries. As growers know too well, sometimes cultivar identity turns out to be something different than what the label says. Our genetics laboratory has developed a way to identify blackberry cultivars by “fingerprinting” them using a DNA test. We run molecular analyses similar to the tests used by the police in real life and on your favorite crime show. In this article, we describe the results of using this test to identify a plant with the original true to type ‘Boysen’, and to determine that ‘Riwaka Choice’ and ‘Boysen 43’ are offspring of the original ‘Boysen’. The NCGR collection does not have true-to-type ‘Young’, or true-to-type ‘Logan’. We have searched throughout the US and Canada looking for true ‘Young’ and ‘Logan’. We will seek other sources to add these historical types to our collection.

Technical Abstract: At the US Department of Agriculture (USDA) National Clonal Germplasm Repository (NCGR), we preserve genetic resources of temperate specialty crops. We are VERY interested in keeping correctly identified genetic resources of our crops and their wild relatives, including blackberries. As growers know too well, sometimes cultivar identity turns out to be something different than what the label says. Our genetics laboratory has developed a way to identify blackberry cultivars by “fingerprinting” them using a DNA test. We run molecular analyses similar to the tests used by the police in real life and on your favorite crime show. We describe the results of using these techniques to identify a plant with the original true to type ‘Boysen’, and to determine that ‘Riwaka Choice’ and ‘Boysen 43’ are offspring (possibly first or second generation) of the original ‘Boysen’. The NCGR collection does not have true-to-type ‘Young’, or true-to-type ‘Logan’. We have searched throughout the US and Canada looking for true ‘Young’ and ‘Logan’. We will seek other sources to add these historical types to our collection.
