“…It exhibits high combining ability, good propagation traits, strong resistance to diseases, and excellent grain quality. Additionally, 1892S-based hybrids demonstrate strong heterosis, tolerance to fertilizers, resistance to lodging, and broad adaptability (Khan et al 2024;Lian-song et al 2016).…”

Hybrid rice has revolutionized food security by leveraging heterosis, a phenomenon where offspring outperform their parents. Sterile lines, crucial for controlled cross-pollination in hybrid breeding, have played a central role in this success. This study delves into the superior alleles of 1892S, a two-line sterile rice line widely used as a female parent in central China. By integrating extensive hybridization data, high-throughput genome sequencing, and bioinformatic analysis (RiceNavi), we elucidate the genetic underpinnings of 1892S's exceptional adaptability. The results reveal its remarkable compatibility as a female parent in over 114 hybrid varieties, potentially due to the influence of Japonica characteristics contributing to strong hybrid vigor. Furthermore, some favorable alleles were identified that were associated with lodging resistance, high yield potential, and improved nitrogen use efficiency etc. The comprehensive characterization of 1892S provides valuable insights for future hybrid rice breeding programs, ultimately facilitating the development of superior rice varieties.
