The pre-harvest sprouting (PHS) in wheat Triticum aestivum L. is a phenomenon that reduces productivity, degrades starch and depreciates the quality of flour. The objective was to evaluate the per se performance of traits linked to grain yield and tolerance to pre-harvest sprouting in wheat genotypes from different breeding programs in Brazil. Besides, to use indirect selection based on traits showing beneficial relationships and greater heritability than the target as a selection strategy. The study was conducted in the years 2010 and 2011 using randomized complete block design with three replications. Thirty-three genotypes of different wheat breeding programs in Brazil were evaluated. The BRS 194 and Frontana genotypes are sources of tolerance to pre-harvest sprouting in wheat. The cultivar TBIO Alvorada has PHS tolerance and high grain yield, and cultivar TBIO Ivaí presenting high grain yield. The percentage of sprouted grains has negative direct relationship with the falling number in adverse cultivating environments. The falling number shows greater heritability than the percentage of sprouted grains, indicating greater reliability in selection for PHS tolerance.
Key words: Triticum aestivum, pre-harvest sprouting (PHS), sprouted grains, falling number.
