      On March 26, 2019, we suffered the sudden loss of our friend and colleague, Philip Stinard, who served as curator of the Stock Center since 1993. We are currently in the process of recruiting to fill this vacant position. While we are currently functioning at a reduced level, we are keeping up with requests (although some larger ones take a bit longer to go out) and had a successful, although considerably smaller, summer nursery this year. We thank our maize colleagues at the University of Illinois, who helped us with our field work this past summer.

      5,542 seed samples have been supplied in response to 399 requests for 2019. These include 203 requests received from 27 foreign countries. Interest in reverse genetics tools, such as the UniformMu sequence indexed stocks, remains high and steady. Presently, requests for UniformMu stocks represent approximately 53% of our total requests. Other popular stock requests include the NAM RILs and other mapping populations, Ac/Ds sequence indexed stocks, Hi‑II lines, haploid-inducing lines, male sterile cytoplasms, Fast-flowering mini-maize, kernel starch quality traits, plant architecture traits, and Maize Inflorescence Project EMS lines

      Approximately 2.0 acres of nursery were grown this summer at the Crop Sciences Research & Education Center located at the University of Illinois. Cool wet, spring weather caused us to delay planting both of our crossing nurseries in a timely. Warm dry weather during the remainder of the growing season allowed for good germination in our crossing nurseries, as well as a normal pollination season; supplemental irrigation was required. There were sufficient stands for a good increase in almost all instances. Harvest was slightly later than normal..

      Special plantings were made for the following stocks:

1. Plantings were made of donated stocks from the collections of Alice Barkan (3 photosynthetic mutant allleles), Frank Kutka (Ga1-s and Ga2-s in Northen adapted backgrounds).

2. Due to the reduction of staffing, maintenance of other stocks have been put on hold. The field space and labor was instead used for maintenance of stocks from the main collection.

      Our IT Specialist's time has continued to be diverted toward Urbana location issues, leaving little time for COOP-specific needs.
