2010 Annual Report

1a. Objectives (from AD-416)
The objective of this cooperative research project is to operate a fall and winter rice nursery for the purpose of advancing plant generations and seed increases.

1b. Approach (from AD-416)
The Agricultural Experiment Stations of Arkansas, Louisiana, Mississippi, and Texas, along with the Dale Bumpers National Rice Research Center will provide technical assistance for operation of rice research field plots; provide rice seed stock; and provide advisory/collaborative assistance as needed.

3. Progress Report
The winter nursery facilities at University of Puerto Rico in Lajas were used to advance breeding materials and increase seed of germplasm stocks. The breeding materials are being used to develop parental lines for use in rice hybrids and for cultivars for aromatic markets and aerobic rice production in the US. The mapping populations are being used in research to identify genes for disease resistance, yield, and grain nutritional quality. The germplasm seedstocks are being used to replenish supplies of accessions in the USDA National Small Grains Collection. Seed and planting plans were sent to the cooperator. Cooperator accurately planted the materials, managed the field during the growing season, and provided facilities and expertise for harvesting and processing the seed, and coordinated seed inspection with APHIS authorities prior to shipment of the seed to Arkansas. This project was monitored through quarterly phone calls or email correspondence as well as two on-site visits.
