Résumé
The overall goal of the proposed research to expand the use of prickly pear cactus (Opuntia ficus-indica) as highly water-use efficient, highly productive, and climate-resilient biomass feedstock for semi-arid regions of the U.S. The project will leverage existing public plant breeding infrastructure through collaboration with the USDA ARS National Arid Land Plant Genetic Resource Unit (NALPGRU) in Parlier, CA and incentivize industry participation by optimizing germplasm selections and testing of production parameters, such as water, fertilizer, viral, microbial and insect pest management, and harvesting inputs, thereby reducing risks for future investments by the private sector. To achieve this long-term goal, four major research objectives and one extension objective will be pursued : 1) Develop molecular identifiers from complete chloroplast genome sequence information for resolving the genetic structure of the germplasm collection of O. ficus-indica to remove genetically identical accessions and resolved species designations ; 2) Evaluate available public germplasm collection of O. ficus-indica for biomass productivity under standard irrigation and fertilization conditions in the field ; 3) Evaluate elite germplasm for optimal water and fertilization inputs, refine productivity models, and perform life-cycle assessment (LCA) and life-cycle costing (LCC) analyses ; 4) Develop effective strategies to overcome barriers to production including overcoming Opuntia stunting disease (OSD) and supporting effective insect management programs for insect pests ; and 5) Develop an innovative extension program to inform interested stakeholders about the benefits of Opuntia production systems in arid and semi-arid regions and to disseminate research results through public outreach and education.The proposed research addresses program priority area A6152 (Biomass Feedstock Genetic Development and Evaluation) by developing biomass feedstock for renewable bioenergy production with extremely low water and nutrient use requirements, while leveraging existing public plant germplasm and breeding resources, and reducing barriers for future investments by private industry stakeholders.
