Golden Rice with β-carotene in the grain helps to address the problem of vitamin A deficiency. Prior to commercialize Golden Rice, several performance and regulatory checkpoints must be achieved. We report results of marker assisted backcross breeding of the GR2E trait into three popular rice varieties followed by a series of confined field tests of event GR2E introgression lines to assess their agronomic performance and carotenoid expression.

- This study focused on genomic data to enhance targeted breeding in rice by characterizing haplotypes at the SD1 locus, crucial for controlling plant height.
- Six SNPs were identified to differentiate various haplotypes in US rice germplasm, leading to the development of KASP assays for efficient large-scale breeding applications.
- The research confirmed the presence of three SD1 alleles in US rice, including two semidwarf alleles, which are vital for marker-assisted selection in breeding programs.
Compositional analyses were performed on samples of rice grain, straw, and derived bran obtained from golden rice event GR2E and near-isogenic control PSBRc82 rice grown at four locations in the Philippines during 2015 and 2016. Grain samples were analyzed for key nutritional components, including proximates, fiber, polysaccharides, fatty acids, amino acids, minerals, vitamins, and antinutrients. Samples of straw and bran were analyzed for proximates and minerals.
