Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 29523 (Inventory No. 26 (1912), pp. 29–30) and the entry for PI 29523 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory gives the donor, a Chinese name, the district where the crop is grown and its uses. 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-SIC-0019110001 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 29523.

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.
SIC stands for Sichuan.
Month 00: the date the seed was gathered is not known.
Year 1911 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

Wilson's note describes a winter crop grown widely on the plain he names, so the accession is classified Landrace.

Collectors and donors

The inventory says the seed was "Presented by Mr. E. H. Wilson", and GRIN-Global lists him as its source. Neither source gives a number or date of gathering, so the infobox gives no collector.

Name

The note gives the Chinese name as Hoa ma, unglossed; GRIN-Global has the same. It is entered as the local name.

Location and georeferencing

The note names the Chengtu Plain, "especially around the cities of Wen Chiang Hsien and Pi Hsien", today's Wenjiang and Pidu districts of Chengdu. The point 30.68, 103.86 is the point of the wiki's Chengdu Plain page, which falls by Wenjiang. It is a point for the part of the plain the note singles out, not for a field. Basis: district point. Uncertainty: about 20 km, enough to take in both towns and the farmland between them.

Dates

The date the seed was gathered is not known, so the collection date is empty. Both sources give 8 February 1911 as the date of receipt, the lot's received date. The identifier therefore carries month 00 and the year of receipt.
