CLEM /S-62-1    Theobroma cacao

 Bartley, B.G.D. (1993)
Notes on the meaning and origins of clone names. B.G.D Bartley. Personal Communications.

Derivation: CLEMentina farm.
Collected by Bartley.
Location: ICTA, Ecuador.

Notes:  Material labelled CLEM and CLM were previously believed to be the same (End et al. 1992) [END92A]. They are now know to be of separate groups of clones.

Progeny from S 62 in Trinidad Cocoa Board Collection 1967.

Bartley, 1993a [BAR93A]. The material introduced into Trinidad in 1967 was identified as H. Clementina S 62 O.P. and H. CLEM. NAC. 5. and thus both were probably seed introductions.

The clone S 62 came from Vinces (according to Muntzing) and is therefore probably the same as EET 62 [ECU]. The H. CLEM 5/ may refer to the Nacional material.

The clones held at ICGT today are CLEM 5/62/1 and CLEM S-62 and it is unclear whether both of these clones are CLEM S62/ progeny (slightly mislabelled) or whether CLEM 5/62/1 represents a progeny of CLEM 5. In either case this material is not the same as Pound's CL and CLM material.
