Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 77397 (Inventory No. 96 (1930), p. 9) and the entry for PI 77397 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory gives the donor, the channel, the date and the place the variety was grown. 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-CHL-UNK-0019280001 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 77397.

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.
CHL is the ISO code for Chile.
UNK: no province is recorded.
Month 00: the date the seed was gathered is not known.
Year 1928 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 inventory describes the seed as a variety grown at Valdivia, which places it in a crop at the named place. Nothing in either source suggests a bred or introduced variety, so the accession is classified Landrace.

Collectors and donors

GRIN-Global lists Dewey, L.H. and Momberg, J.A. in its collector field. The printed inventory says the seeds were presented by Momberg through Dewey and does not say either gathered them, so the infobox gives no collector.

Location and georeferencing

The coordinate is Valdivia, at the point OpenStreetMap gives for the commune (relation 1785691), -39.81, -73.25, which falls in the city. It marks the city the source names, where the variety was grown. Basis: settlement point. Uncertainty: about 6 km, the city's extent plus 1 km for the two-decimal form. No province is entered: GRIN-Global gives Los Lagos, the region Valdivia belonged to until 2007, and Valdivia is now in Los Ríos Region.

Dates

The date the seed was gathered is not known, so the collection date is empty. Both sources give 20 September 1928 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.
