Research Project: PUERTO RICO RICE NURSERY

Location: Dale Bumpers National Rice Research Center

2011 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, genetic mapping populations, and genetic resources from the USDA National Small Grains Collection. The breeding materials are being used to develop new cultivars for conventional and specialty markets. The mapping populations are being used in research to identify genes for disease resistance, yield, and grain chalk. Seed was prepared for planting in Arkansas, and planting plans were sent to the cooperator in Puerto Rico. Cooperator accurately planted the materials, managed the field during the growing season, provided facilities and expertise for harvesting and processing the seed, and coordinated seed inspection with APHIS authorities prior to shipment of the harvested seed to Arkansas. This project was monitored through quarterly phone calls or email correspondence, as well as two on-site visits.
