Kia Ora, This is our second year of running this heritage potato collection trial with the aim of nourishing them so well they will grow out of having viruses, and small crops etc. This is the alternative we see (based on the principles of epigenetics), to tissue culturing them to remove viruses, as most others are doing. I do not see tissue culturing as a long term solution (reducing genetic diversity and removing plants from the process of co-evolution) or even a short term solution for ordinary gardeners, because of cost.
Our New Zealand heritage potato collection has been endangered in recent years by a lack of effective rouging and selection and the recent arrival of the psyllid and so we are endeavouring to strengthen them again, back to having heavy crops as they used to do years ago. We made a lot of progress last season, through heavy rouging, selection and super nourishment, and we were very happy with the results.
