J.  aGenetics of lodging-resistance in wheat.  c2005  aKnowledge on the inheritance of lodging-resistance is of great value for the development of new wheat (Triticum aestivum) varieties. Crosses among four different bread wheat genotypes were evaluated in the field. The analysis was based on three fixed (P1, P2 and F1) and three segregant (F2, BC1F1 and BC2F1) generations. Means and variances were computed for each generation in all crosses and the gene effects estimated. The lodging-resistance factor method (cLr) was measured. Partial or complete dominance of the lodging-susceptible over the lodging-resistant parent in each cross was evident. Results showed a large genetic variability among the genotypes.  aheritability  aquantitative genetics  aTrigo  aTriticum Aestivum  aAção gênica  aCoeficiente de resistência ao acamamento  aGene action  aGenética quantitativa  aHerdabilidade  aLodging-resistance factor index1 aSILVA, J.
