Interpretive Summary:

Technical Abstract: Rice is a staple crop that is consumed globally. Negative effects from climate change across the world include decreased water availability. While balancing adverse effects on the environment, abiotic stresses such as drought will be a major cause for concern. One way of working towards a solution is integrating beneficial loci from wild rice donors with elite rice cultivars. These genetic resources, known as chromosome segment substitution lines (CSSLs) and near introgression lines (NILs), have introgressions or parts of the wild rice genome within its genetic makeup but mainly consist of the elite cultivar, also known as the recurrent parent. For this study, I aim to evaluate CSSLs and NILs under water deficit conditions for their potential of serving as Rice is a staple crop that is consumed globally.

For this study, I aim to evaluate CSSLs and NILs under water deficit conditions for their potential of serving as future pre-breeding material. Cybonnet and Jefferson, U.S. cultivars bred for adaptation to the Southern rice belt, along with their CSSLs and NILs, will be tested in this study.
