N.  aYield QTL analysis of Oryza sativa x O. glumaepatula introgression lines.  c2013  aThe objective of this work was to evaluate the yield performance of two generations (BC2F2 and BC2F9) of introgression lines developed from the interspecific cross between Oryza sativa and O. glumaepatula, and to identify the SSR markers associated to yield. The wild accession RS‑16 (O. glumaepatula) was used as donor parent in the backcross with the high yielding cultivar Cica‑8 (O. sativa). A set of 114 BC2F1 introgression lines was genotyped with 141 polymorphic SSR loci distributed across the whole rice genome. Molecular analysis showed that in average 22% of the O. glumaepatula genome was introgressed into BC2F1 generation. Nine BC2F9 introgression lines had a significantly higher yield than the genitor Cica‑8, thus showing a positive genome interaction among cultivated rice and the wild O. glumaepatula. Seven QTL were identified in the overall BC2F2, with one marker interval (4879‑EST20) of great effect on yield. The alleles with positive effect on yield came from the cultivated parent Cica‑8.  aBreeding  aGenetic markers  aQuantitative trait loci  aRice  aArroz  aMarcador molecular  aMelhoramento  aMelhoramento genético vegetal  aOryza sativa  aAB-QTL  aBase genética  aDesempenho produtivo  aGenetic pool  aOryza glumaepatula  aRegião-alvo do genoma  aTarget genome region  aYield performance1 aVIANELLO, R.
