Assam–China hybrid stock
Not a cultivar and not a landrace but a category of planting material: the mixed-ancestry stock that resulted when Chinese small-leaf seed and Assam large-leaf plants were grown together and allowed to cross, deliberately and accidentally, across the nineteenth and twentieth centuries. Because tea does not readily pollinate itself, any two varieties planted near each other will hybridise, and most of the tea planted in India, Sri Lanka and much of Africa is hybrid material rather than either parent variety in a pure form.
Where it sits in the botany
Assam–China hybrid stock is recorded under Hybrid, the variety group one level above cultivar. It is associated with India, which is where it was selected or is most widely planted rather than the only place it grows.
Also transliterated as: assam china hybrid.
Where it came from
Arose in the Indian and Ceylonese plantations where Chinese seed and Assam indigenous plants were established alongside one another, and was subsequently the base population from which many numbered clonal selections were made.
How firm this is: Inferred rather than taken from a primary breeding or registration record. The general history is well established. The specific ancestry of any given estate’s stock is usually unrecorded and cannot be reconstructed from the plants.
What the plant is like
Intermediate in everything — leaf size, hardiness, vigour, cup character — and enormously variable, because hybrid stock is a description of ancestry rather than of a plant. Most of the numbered clone series of India, Sri Lanka and East Africa were selected out of populations of it.
What it is usually made into
The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.
- Black tea — Tea taken deliberately through full enzymatic oxidation, giving the dark leaf, amber-to-red liquor and malty or brisk character most Western drinkers think of as simply 'tea'.
Other cultivars in Hybrid
Guides covering this cultivar
- Why a tea plant will not pollinate itself, and what follows from it — Tea is largely self-incompatible: a plant will not readily set seed with its own pollen. That single reproductive fact is the reason seed-grown fields are variable, the reason cultivars must be clonal, and the reason tea breeding is slower than breeding almost any annual crop.
- Sinensis, assamica, and the third name that will not settle — Tea botany has two levels, and most tea writing collapses them into one. Above the cultivar sits the botanical variety, and the difference between the small-leaf and large-leaf varieties explains more about a tea than any cultivar name does.
