Knowledge 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.

The objective of this work was to assess the relationship between macrofauna, mineralogy and exchangeable calcium and magnesium in Cerrado Oxisols under pasture. Twelve collection points were chosen in the Distrito Federal and in Formosa municipality, Goiás state, Brazil, representing four soil groups with varied levels of calcium + magnesium and kaolinite/(kaolinite + gibbsite) ratios. Soil macrofauna was collected in triplicate at each collection point, and identified at the level of taxonomic groups. Macrofauna density showed correlation with contents of kaolinite, gibbsite and exchangeable Ca + Mg in the soils. Mineralogy and exchangeable Ca + Mg had significant effects on taxonomic groups and relative density of soil macrofauna. The termites (Isoptera) were more abundant in soils with low exchangeable Ca + Mg; earthworms (Oligochaeta), in soils with high levels of kaolinite; and Hemiptera and Coleoptera larvae were more abundant in gibbsitic soils with higher contents of total carbon. |
