I recently pollinated 13 varieties with a male Princess Diesel. For the most part, the sativa dominant strains like AK-47,Dynamite(not the SPG Dynamite from BC), Trainwreck and VBS were small. The C-99 x PD were tiny. The indica dominant strains like ST#3 x PD were the largest. Afghan Bullrider x PD, PD f2s and Afghani#1 x PD were large and dark. The exception was the Jedi x PD which was small and tan colored,as was the Dynamite(San Diego sativa dom clone only) x PD.
but the seed-size is also connected with the environment right? i saw that a fully-seeded mj gives a lot of little seeds ...while the less-pollinated plant (from the same strain) is making larger & more fat beans
All of my plants were fully seeded(1500-2000 seeds per plant) and I saw no difference in size between the fully seeded Afghan Bullrider that I had this time and the partially seeded Bullrider I did a few months ago. I would suspect that the seed size is genetically determined.
Sorry, Smoke. I don't own a camera.
Sam, what is the Yunnan like? Short indica from the mountains?
