I quote to you from a USDA publication (Catalog of the Tobacco Introductions in the US Dept of Agriculture's Tobacco Germplasm Collection; ARM-S-27/October 1982; ISSN 0139-3779): pg3 "Plant type was judged from the field appearance of each TI. Types assigned included burley (B), cigar filler (CF), cigar wrapper (CW), flue-cured (FC), Hungarian (H), primitive (P), pale-yellow (PY), Turkish (T), and no type identified (NT). Names are based on resemblances, not potential use."
"Cigar-filler.--Lines characterized as cigar filler have erect growing leaves that are narrow; some are relatively long. The plants are generally short, have close internodes, and are dark green. In some lines, the leaves are so long that they droop, and the ends may touch the soil. These types usually stay green until maturity, when the leaves go from green to brown. This is a large group and probably contains some dark-fired and cigar-binder types."
"Primitive.--All types described except primitive have a main central stem and do not branch very profusely until after the top is broken out. The primitive types are characterized by profuse branching, and many lines do not have a central stem. The plants are generally low growing with small leaves, which are extremely narrow. The primitive types bloom quite early and produce very few leaves, but the branches contain many small leaves."
"Turkish [Oriental].--The Turkish group contains lines that resemble Turkish or oriental cultivars. The Turkish group is variable and ranges from pointed- to rounded-leaf types. The plants so classified are small and have smaller leaves than most other types; some have leaves with naked petiole, and some of the plants lodge. The Turkish types flower early but produce a flower head that protrudes well above the top leaves [as opposed to Hungarian types that have a different morphology with recessed flower heads]. The classification in this catalog does not associate the type with the Turkish aroma characteristics."
