What are the chromosomes in triploid hops?

In triploid hops, the correct number of chromosomes is 30. This is obtained from the fact that hops (Humulus lupulus) traditionally have a diploid chromosome number of 15. Since triploids are formed when there are three sets of chromosomes, the total number becomes 3 times 15, resulting in a total of 45 chromosomes.

Triploidy in hops is significant because it introduces certain advantages, such as increased vigor and potentially higher yields. While the chromosome number is higher than what would be seen in diploid varieties, the genetics also lead to differences in the production of certain secondary metabolites, including alpha and beta acids crucial for brewing.

The reduced viability and fertility of triploids, due to the odd number of chromosome sets, leads to characteristics that can influence breeding programs in horticulture. Understanding these genetic underpinnings is crucial for both breeding endeavors and for the practical application in hop production for brewing.
