NASC sent >50,000 individual stocks per year since 2007, and >100,000 individual stocks per year from 2013-2018 with a maximum (so far) of >180,000 total seed tubes sent in one single year. Stocks are provided under identical cost recovery conditions to academic and commercial researchers. Non-transgenic stocks are sent gratis to K-17 institutions (and in special cases).
