BPT2848 (IET28692): A Black Rice with High Protein Content

Rice serves as a dietary staple for nearly half of the global population, making it a crucial source of nutrition. Enhancing the protein content of rice can significantly contribute to alleviating protein-energy malnutrition, which affects over one-third of the world’s children. BPT 2848 (IET 28692), a newly developed black rice variety derived from the cross between RP Bio 226Ē1 and IRGC 48493 through pedigree breeding, stands out for its high protein content of 10.5ą in polished rice, a notable improvement over conventional white rice (6–7ą). Evaluated across nine locations in seven states during the IVT-Biofortification trial, BPT 2848 consistently exhibited superior protein levels, exceeding 10ą at five locations, with the highest content observed at Cuttack (13.33ą) and Jeypore (13.17ą). Additionally, BPT 2848 demonstrated high total phenol content (123.31 mg/100 g), flavonoid content (784.54 mg/100 g), and antioxidant activity (86.63 mg/100 g), contributing to its potential health benefits. Unlike traditional glutinous black rice, BPT 2848 possesses intermediate amylose content and an alkali spreading value, resulting in a soft and flaky texture upon cooking. With a medium slender grain, a test weight of 13.5 to 14.0g, and a mean grain yield of 4415 kg/ha, BPT 2848 combines nutritional superiority with agronomic viability. This high-protein, bioactive compound-rich black rice presents an appealing option for promoting dietary protein intake and enhancing nutritional security.
