The different types of varieties defined should provide additional opportunities to exploit the biomass of sugarcane crop for different end-uses.
As a consequence, changes in the average value of some traits (e.g. flowering date) could be due to a change in the frequency of certain types of varieties (e.g. early varieties), instead of reflecting a phenotypic change in the variety per se.
In this regard, one remarkable observation is that, inasmuch as legions of well documented examples exist where divergent types of varieties have been generated under domestication, very few, if any, examples exist where truly significant reproductive isolation has been witnessed.
Furthermore, the difference in the extent of population structure and relatedness between rapeseed, potato, sugar beet, and maize may partly be due to the different reproduction systems and types of varieties bred in a particular crop.
If you, like me, were unfamiliar with the beautiful JACAMAR, here is a photo of what one type of the variety looks like.
