Título:  Soybean rust resistance sources and inheritance in the common bean (Phaseolus vulgaris L.).

Conteúdo:  Abstract: Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi, has been reported in common bean (Phaseolus vulgaris L.) cultivars and elite lines that were infected under controlled and natural field conditions in South Africa, the United States, Argentina, and Brazil. Although SBR is currently not a top priority problem for the common bean crop, many bean breeders are concerned about this disease because of the high severity and virulence diversity of P. pachyrhizi and its broad host range. In this study, a set of 44 P. vulgaris genotypes were tested for resistance to P. pachyrhizi; these genotypes included resistance sources to several fungal common bean diseases, carioca-, black- and red-seeded Brazilian cultivars, and elite lines that were developed by the main common bean breeding programs in Brazil. Twenty-four SBR resistance sources were identified. They presented the reddish-brown (RB) lesion type, characterizing resistance reactions. In addition to the RB lesion type, the PI181996 line presented the lowest disease severity mean score, considering its associated standard error value. For this reason, it was crossed with susceptible lines to study the inheritance of resistance. The results support the hypothesis that resistance to SBR in PI181996 is monogenic and dominant. We propose that this SBR resistance gene, the first to be identified and characterized in common bean, might be designated as Pkp-1.

Título:  Effect of integrated soybean with sorghum and brachiaria system on soil carbon and nitrogen.

Conteúdo:  The objective of this work was to analyze the effect of the integrated soybean system with sorghum and brachiaria on the levels of organic carbon, total N and mineral N in the soil. Super short cycle soybean BRS 7580 was planted, and subsequently, forage sorghum BRS 655 and BRS Piatã brachiaria were planted between the lines of the soybean. The levels of organic carbon, total nitrogen, ammonium, nitrate and mineral nitrogen/total nitrogen ratio were evaluated. The soil under Cerrado showed higher levels of organic carbon at all depths. There were no significant differences between treatments and the Cerrado for total nitrogen content in the deepest layers of the soil. All treatments showed a stratified distribution for the ammonium content, with higher values in the more superficial layers, decreasing in the deeper layers. Nitrate was not detected in the soil under Cerrado. Integrated crop treatments showed higher nitrate values than singles systems. In general, nitrate values were higher in the more superficial layers, with a significant decrease in the intermediate layers, increasing again in the 40-60 cm layer. The mineral nitrogen/total nitrogen ratio treatments with single or intercropped soybean maintained the same nitrate results pattern.
