Core Viewpoint - The National Saline-Alkali Rice Technology Innovation Center has made significant progress in creating new breeding materials for salt-resistant rice, achieving breakthroughs in high salt tolerance varieties [2][3]. Group 1: Breeding Materials and Techniques - The center has developed new breeding materials that can withstand a salt concentration of 10‰, with survival rates exceeding 80% for 179 materials at this concentration [2]. - The team identified 6 positive regulatory genes and 8 negative regulatory genes related to salt tolerance, as well as a key gene STRK1 that significantly enhances salt-alkali resistance in rice [2]. - The survival rate of the "Salt Recovery Line 0W590" material reached 93.5% after 17 days under 10‰ salt concentration, while "Salt Recovery Line D1849" had a survival rate of 68.7% under 12‰ salt concentration [2]. Group 2: Agricultural Impact and Strategic Goals - The development of high salt-resistant materials is expected to contribute to transforming "hundreds of millions of acres of wasteland into granaries," aligning with the national food security strategy of "storing grain in the land and technology" [3]. - The center has produced several salt-alkali resistant rice varieties over the past five years, with 11 varieties approved, including the first salt-resistant sterile line "Salt 416S" in 2023 [3].
