A hybrid sterile locus leads to the linkage drag of interspe

　　Interspecific hybridization plays an important role in rice breeding by broadening access to desirable traits such as disease resistance and improving yields. However, interspecific hybridization is often hindered by hybrid sterility, linkage drag, and distorted segregation. To mine for favorable genes from Oryza glaberrima, we cultivated a series of BC4 introgression lines(ILs) of O. glaberrima in the japonica rice variety background(Dianjingyou 1) in which the IL-2769(BC₄F₁₀
