Physiology of lodging resistance and vegetative reserve storage of rice hybrids for the US production system. Lee Tarpley, in cooperation with RiceTec, is completing a study to identify physiology-based characteristics of lodging resistance. These characteristics will be used by RiceTec to further the incorporation of lodging resistance in their hybrid development program. In addition, Lee Tarpley is studying how the various parts of the hybrid plants are temporarily storing and using carbohydrates (sugars and starch) and nitrogen-containing compounds (such as protein). The timing and extent of use of these reserves differ between the hybrids and the Texas cultivars. These differences present some unique opportunities for hybrid improvement and management. The 2003 field sites are in Beaumont and Eagle Lake. This study is supported by RiceTec Inc. |
