Performance of soil management systems was initiated in 1995 in a field experiment in Dourados, MS,Brazil, with the following systems: CS ? conventional tillage; NTS ? no-tillage; ICLS ? integrated crop-livestock with soybean (Glycine max (L.) Merr.) and pasture under no-till, rotating every two years, and PP? permanent pasture. Pastures (Brachiaria decumbens) were grazed by heifers with stocking rate adjustedto constant supply of forage. The hypothesis was that rotation of crops and pastures would be moreefficient and present beneficial effects to the environment. More complex and diversified productionsystems may exhibit synergism between components to result in better soil physical structure, greaterefficiency in use of nutrients by plants, greater accumulation of labile fractions of soil organic matter,greater diversity and biological activity in soil, and lower occurrence of nematodes and weeds. Better soilconditions in ICLS allowed greater resilience; over the years of assessment soybean and pasture yieldswere less affected by drought and frost. The ICLS was very efficient, accumulating soil C and reducingemissions of greenhouse gases. Soil quality was improved in integrated systems with larger numberof components and greater interaction between these components (ICLS) compared to simple systems.Based on soil attributes, we affirmed in this long-term study that the ICLS system is agronomically andenvironmentally efficient and sustainable. |

Despite their economic importance, some tropical crop species are largely neglected when it comes to conducting genetic studies characterizing target traits for breeding. Herein, genetic and phenotypic parameters as well quantitative trait loci (QTL) are described for the first time in a full-sib progeny of sweet passion fruit (Passiflora alata). A hundred F1 individuals were evaluated in two locations for seven fruit traits: diameter of fruit (DF, in mm), length of fruit (LF, in mm), weight of fruit (WF, in g), thickness of fruit skin (TS, in mm), weight of fruit skin (WS, in g), weight of fruit pulp (WP, in g) and soluble solids (SS, in °Brix). Mixed models fitted complex, unstructured genetic variance-covariance matrices for all traits in phenotypic analysis. Because of important genetic correlations among skin and pulp traits, multiplicative index selection to select the most promising individuals was successfully applied. A previously reported integrated map supported composite interval mapping (CIM) analyses. In total, we found 22 QTLs mapped in seven out of nine linkage groups. Heritabilities (from 59.8 % to 82.7 %) and proportion of phenotypic variance explained by the QTLs (from 42.0 % to 64.3 %) were comparable for each trait. Principal component analysis on TS, WS and WP showed that the first two principal components (PCs) accounted for 93.6 % of the total variability. CIM analyses on these two PCs revealed five putative QTLs controlling variation for these three traits simultaneously. Thus, genetic improvement for sweet passion fruit should be based on correlations between traits and QTL-related information can be a useful tool.
