 Collecting and banking seeds of wild plant is a complementary tool for plant diversity conservation, as well as an important practice on germplasm’s longterm preservation. Although the sampling methodology and collecting technical standards had been well developed in crop germplasm preservation activities, it is not able to be fully adopted for the wild plant species due to the objective and species differences. The initial quality of seeds is critical for longterm storage and its associated material and information are also essential for the further utilization, technical standards for collecting seeds from wild plants are developed in many countries to improve the quality of seeds collection and data, but are not widely available in China. In this paper, we proposed that seeds, herbarium vouchers, associated field data, images and DNA samples shall be collected simultaneously if it is possible as an entire collection unit, the technical standards for each of the five components of collection unit are also presented here, together with protocols in sampling strategy and seed postharvest handling.
