Grain quality has a major importance in the Brazilian wheat market and industry. However, one of the major limiting factor in quality wheat production is the presence of Aluminum (Al) toxicity in the soil. Twenty-five, 50 and 52 percent of soils in the world, Brazil and Paraná state respectively, contain acidity. The present study had the objective of estimating genetic parameters to identify gene action and heritability of traits in segregating populations of wheat. The Al screening in hydroponic solution and MS-SDS sedimentation analysis for quality were used in a generation mean analysis. Predominantly additive gene effects were present controlling the traits under evaluation, indicating possibilities of selection progress. The relatively high values of narrow sense haritability for sedimentation volume in the crosses IPR 85/OR 1, Iapar 78/Minnpro, Grandin/Iapar 46 and Iapar 53 Trigo BR 23, and Al tolerance in IPR 85/OR 1 and Grandin Iapar 46 suggests that successful selection can be accomplished in the early segregating generations. |
