Helium static prototype. Users interacting with the large static prototype implementation of our pedigree visualization. In this example 2 and 6 row ecotypes are coloured green and blue respectively and varieties (nodes) are sized based on their contribution to the overall pedigree in terms of the number of lines that are derived from them. This shows which lines are most commonly used in barley breeding in the UK. The 2/6 row division is one of the important characteristics used to differentiate barley worldwide. 2 row barley is primarily of spring type and used in brewing and distilling while 6 row varieties are used in feed due to decreased quality characteristics for the brewing and distilling industry. Consent was obtained from both participants for publication of their images.
