Little off topic but close enough, thought I could chime in with a little Dosi experience.
Crossed Royal Kush male with the Dosido's clone from Nor Cal. Cross has some great phenos, the Royal brought in more girth in many phenos, and added some different terps. Had a really nice pheno that was still dense and more solid, dosi dough smell, at least as frosty if not more of a afghan white frost, with way more girth on the branch. Sadly, didn't clone it. Out of maybe 50-60 females, didn't notice any herms, and very little mutants or runts.
Took the, (Royal Kush x Dosi) and crossed it back to the same Dosi clone. Probably incorrectly labeling it, but have been referring to it as a Royal Dosi BX1. When I made the cross, I thought the Dosi was so great, would be nice to have seed stock that was close to the clone only. After seeing a small population finished, and a larger population vegging, I feel like the cross was maybe a step backwards, luckily I still have plenty of the normal (Royal x Dosi), before the back cross. I am testing a larger population myself at the moment.
What I noticed from the back cross so far. A solid 30+% have a weird serrated leaf pattern. All the serrated phenos have extremely wide leaves. I also noticed a very strange stretch in around 10% of the phenos. The stretch appeared between the cotyledons and the first set of true leaves, a good 1-1.5" stretch. In all my years popping seeds, I have never seen a plant stretch like this. Even in low light levels a seedling with stretch up grow cotyledons and a set of leaves followed right above it, then maybe fall over, but this is not the case. The light was intense, this stretch seemed genetic and only happened in apx 10% of the population.
My friend just finished a decent population of the Royal Dosi BX1, outdoors, in good conditions. Everything was really frosty, but it was a little to dainty. Had density within the floral clusters, but they just didn't connect completely or have enough girth. Also late flowering herms on the lower half, popped up in the crotch of the branchs.
Ill chime in when this next population is finished or closer. The Dosi is great no doubt, but I have a feeling that it is as inbred as it can take, and any further inbreeding may not do it justice. Hopefully I am wrong, and some great freak will pop up and wow me, but the normal Dosi is great, and Dosi hybrids as well, not sure more inbreeding can improve on it.
