NPG Deep Chunk IBL is a seed accession of an inbred cannabis line said to descend from Afghan stock, held by the U.S. National Plant Germplasm System (NPGS) as G 33703. Angus donated the seed, and the system received it on 22 August 2023.[1] The donor's note says the line is said to have been bred in America by Tom Hill from an Afghan landrace collected in the 1970s, and that this seed is a Spanish continuation of it.[1]

Background

The note reports that enthusiasts regard Deep Chunk as a pure Afghan line that has never been crossed with anything else, and that its source is said to have reached northern California in the late 1970s. The donor disagrees that it can count as an authentic Afghan landrace: it has had about five decades of selection of single plants in the West, aimed at strong seedless flower heads, and, the note says, a field of Deep Chunk has no equivalent in Afghanistan.[1]

The donor's argument

The note sets the line against a wider claim about Asian drug-type landraces. In the donor's view there is no history of ganja growing north of about 30° N, roughly western Uttar Pradesh; north of that line the traditional product of the Punjab is bhang, and further north, in Pakistan's North-West Frontier and the Hindu Kush, it is charas. Northern populations, the donor argues, have a long history of selection in bulk, and southern ones of frequent selection of single plants, which is why plants high in THC relative to CBD are much commoner in the south.[1]

The plants

The description the note goes on to quote calls it a true-breeding broad-leafleted line, cleared of weak and off-type plants, that flowers in about 56 days indoors and in September outdoors, with thick stems, short internodes, dense resinous flower heads and an earthy, herbal smell. It names grey mould as its weakness.[1]
