Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 44712 (Inventory No. 51 (1922), p. 53) and the entry for PI 44712 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory gives the region, the donor and a general note on hemp oil in Manchuria. GRIN-Global states that the lot "no longer exists and can not be requested", so the page gives the lot as gone. No conservation priority is assigned.

Identifier

The identifier NPG-CHN-UNK-0019170001 follows the wiki's seed-accession grammar: holder, ISO 3166-1 alpha-3 country, province segment, month, year, sequence. The department's own number for the lot is PI 44712.

NPG stands for the National Plant Germplasm System of the United States Department of Agriculture, whose database, GRIN-Global, carries the department's plant introductions.
CHN is the ISO code for China.
UNK: no province is recorded.
Month 00: the date the seed was gathered is not known.
Year 1917 is the year the department received the lot.
0001 is the lot's place, in plant-introduction order, among the holder's lots from the same country, province, month and year.

Classification

The seed came from an experiment station in Korea, labelled only as from Manchuria; the note is general and does not describe where this seed was grown. The accession is classified Unknown.

Collectors and donors

GRIN-Global lists M. Toyonaga as its source; the printed inventory says he presented the seed. No one is said to have gathered it, so the infobox gives no collector.

Location and georeferencing

The inventory names Manchuria and nothing finer. Manchuria is a region that then took in three Chinese provinces, and no province or place within it is named, so no province is entered; a point for the whole region would describe the region, not the lot, so the page has no point and the map is off. GRIN-Global files the lot under Kyonggi, Korea, the province of the experiment station that sent it. The printed entry says the seed is from Manchuria, and the page follows the print: the country is China.

Dates

The date the seed was gathered is not known, so the collection date is empty. Both sources give 4 May 1917 as the date of receipt, the lot's received date. The identifier therefore carries month 00 and the year of receipt, and the province segment UNK.
