Harvesting sun root seeds? (sopuli.xyz)

I have been planting and harvesting sun root for a few years but I've never been able to harvest the actual seeds of the plants, regardless of having the flowers atracting insects.

Has anyone been able to harvest the seeds? If so, how and when? My intention is to try to grow from seed and see if some variation occurs.

My sun roots develop the usual yellow brownish tubers but occasionally I find some which are reddish or even deep purple; the pulp remains white or lightly yellow but the flavour profile changes drastically, with the purple ones having a very pronounced hazel nut hint.

I've kept and planted only purple tubers and the plants do not return a higher yield of such tubers. It may return a few purple ones, it may grow only standard tubers.

I've even considered it a response of the plant towards soil conditions, sun exposure or amount of watering and it makes no difference.

There is no way, in my limited knowledge, to increase the frequency of such tubers, unless I was able to selectively breed towards such result like what I've done with hot peppers.
