  1. SSSL was the abbreviation of single segment substitution line. Si represented the code of SSSLi. t(n)|t(n-1) indicated the developmental stage from n-1 to n, 7d. a and d were homozygote and heterozygote effects respectively, estimated by \(SSSL_{i} - HJX74\)(where i represented homozygote or heterozygote). aa, ad, da and dd were additive-additive, additive-dominance, dominance-additive and dominance-dominance epistasis, respectively, estimated by \((D_{kl} + HJX74 - S_{k} - S_{l} )\), where \(D_{kl} ,S_{k} ,S_{l}\) indicated dual segment and its two single segment materials respectively, which might be homozygotes or heterozygotes. Sign “-” meant to descend tiller number due to the alleles from donors. Superscripts “* and **” indicated the significance at 5% and 1% level, respectively.
