The objective of the study was to evaluate the influence of corn-crotalaria intercropping on the fermentative process, the organic acid profile, and the chemical composition of the silages produced. The trial was implemented in a randomized block design, in a 3 × 2 factorial scheme, with three types of intercrops [single corn (CSC), corn + Crotalaria juncea (CCJ), and corn + Crotalaria ochroleuca (CCO)] in two spatial arrangements [A1 (corn and legume sown in the same row) and A2 (corn and legume sown in alternate rows)], with six repetitions per treatment, evaluated in two agricultural years. The silages were evaluated for fermentative losses, pH, organic acids, ammonia nitrogen, chemical composition, and in vitro dry matter degradability. The least amount of gas loss was observed in the silages produced in the first year with CCJ and the CCO (11.6 g/kg dry matter for both). The lowest pH values were verified in the silage of the treatments CSC and CCJ (3.46 and 3.44, respectively) in the second year, and for ammoniacal nitrogen (NH3-N), the lowest concentrations were observed for CSC and CCO (120.7 and 138 g/kg total nitrogen, respectively). Higher levels of lactic acid and crude protein were obtained in the silage produced with CCJ, in both years of evaluation, whereas lower contents of acid detergent fiber were observed in the silage of the treatments CSC and CCO in the spatial arrangement A2. The largest coefficients of in vitro dry matter degradability were observed in the silages originated from CSC and CCO (820.6 and 798.0 g/kg dry matter, respectively). These results suggest that the intercropping of corn with C. ochroleuca sown in alternate rows increase the crude protein content without reducing the fermentative and nutritional quality of the silages. The planting of both legumes in the same row with corn negatively influenced the fermentative and nutritional characteristics of the silages, and this method is not recommended.

The objective of this work was to identify major and minor?effect quantitative trait loci (QTL) for resistance to races 3, 9, and 14 of soybean cyst nematode (SCN) in Hartwig cultivar; to map new resistance QTLs for these races; and to check for the existence of epistatic interactions between QTLs. Cultivar Hartwig is an important resistance source to SCN. Recombinant inbred lines (RIL) obtained from a cross between 'Hartwig' (resistant) and Y23 (susceptible) were evaluated regarding resistance to the three races. New genomic regions for resistance to SCN were identified by microsatellites. Four QTLs, which explained between 12 and 34% of phenotypic variance, were detected for resistance to race 3 in linkage groups (LG) A2, G, J, and M. The QTL in LG G is also important for resistance to race 9. Epistatic interactions were detected between loci, which indicate resistance to races 9 and 14. There are high and low? effect resistance QTLs to SCN.

A cultivar Hartwig é uma importante fonte de resistência ao NCS. Linhagens endogâmicas recombinantes (LER) obtidas do cruzamento entre 'Hartwig' (resistente) e Y23 (suscetível) foram avaliadas quanto à resistência às três raças. Novas regiões genômicas de resistência ao NCS foram identificadas por microssatélites. Quatro QTLs, que explicaram entre 12 e 34% da variância fenotípica, foram detectados para a resistência à raça 3 nos grupos de ligação (GL) A2, G, J e M. O QTL no GL G também é importante para a resistência à raça 9. Interações epistáticas foram detectadas entre loci, o que indica resistência às raças 9 e 14.
