Mystic Funk, very interesting project.
I'd categorize phenotypes by a combination of leaf size,growth structure, and aroma. E
Extreme NLD - P1 landrace Mexican varieties might flower for + 20 weeks. NLD / WLD P1 landrace Mexican varieties might flower for 11 - 12 weeks. Taliban, drug cartels introduced hybridization fairly early in Mexico. I'm sure your friend saved seeds from his or her favorites. i wish i still had the coffee can of 1975 Highland Oaxacan Gold seeds.
Elchisicas (sp?) here on IcMag noted 8 cannabis varieites were grown in Oaxaca.
Most of the Acapulco Gold grows I've seen had WLD influence. 1960 - 1970 Acapuclo Gold would probably flower for 17 - 19 weeks. Mexicani-ar noted that Bodhi's Acapulco Gold flowers for 17 - 19 weeks.
I selected two long flowering phenotypes from 2010 Copalita Oaxacan. Copalita - 1 flowers for 16 weeks and Copalita - 4 flowers for 20 weeks. The high and growth structure from Copalita - 1 is Mexican all the way. The high from Copalita - 4 is Asian influenced.
Colombian seeds are dark brown with black mottling / striping. Colombian leaves would be ultra thin NLD even as seedlings.
SamS did a contest / question where he ask. The mother came from a plant with small seeds and the father came from a plant with big seeds. What size will the seeds of the progeny be? The answer is small as seed size follows calyx size, and the female traits determine calyx size. Calyx size is a factor of the grow, bigger mature plants will have bigger calyxes, smaller mature plants will have bigger seeds. In general extreme NLD sativas will have smaller seeds and WLD indicas, bigger seeds.
The calyx size on Copalita Oaxacan -4 ( 20 weeks) are tiny and if the pollen took the seeds will be tiny.
