    Abstract: O tomateiro possui estreita base genética, devido ao intensivo melhoramento e domesticação de espécies selvagens. Por outro lado, acessos são fontes potenciais de germoplasma contra insetos-praga dessa cultura. O objetivo deste estudo foi avaliar os danos causados por Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) em folhas e nas plantas de Lycopersicon esculentum var. cerasiforme. A variabilidade fenotípica e qualitativa entre 15 acessos, os danos nas folhas e plantas após 20 dias foram avaliados. O dano nas folhas e plantas foi avaliado por escala notas. De maneira geral, o acesso CCAUFES 40 foi a mais resistente a T. absoluta, o que indica que o mesmo possui potencial como fonte de germoplasma para o melhoramento de plantas de tomate contra T. absoluta.

    Abstract: Fruits in the ripe red stage of thirty three tomato (Lycopersicon esculentum Mill.) accessions from CCA-UFES germplasm collection, being 15 "Cherry type" and 18 "Salad type", were characterized based on the following morphooagronomic descriptors: average fruit weight; average fruit length; average fruit diameter; peduncle scar diameter; fruit mesocarp thickness; soluble solids and fruit pH. Based on the data from the soluble solids and fruit pH, the flavor variable was calculated by the ratio TSS/pH². Variance analysis and simple and partial correlations were calculated, and the accessions were clustered in flavor classes. Based on the statistical model of distribution of frequencies, four classes were formed for flavor variable. The largest portion (33%) of the accessions of salad type were located in the lowest class (0.05-0.12 ºBrix.pH-2), corresponding to the accessions with not so desirable a flavor, while the largest portion (30%) of the accessions of the "cherry" type were clustered in the next class above (0.13-0.20 ºBrix.pH-2). The possibility of concomitantly obtaining genetic gains for flavor, weight, length and mesocarp thickness of the fruits was demonstrated.

    Abstract: The objective of this work was to evaluate the efficiency of reciprocal recurrent selection in producing hybrids of popcorn (Zea mays) from superior endogamous progenies, with full-sibling families. The reciprocal recurrent selection program involved the 'Viçosa' and 'Beija-Flor' popcorn populations. Tests of the hybrids S0xS0 and S1xS1 were carried out in lattice design, in the agricultural years 2002/2003 and 2004/2005. The two assays included common commercial controls, allowing for the comparison of the hybrids performance. Productivity and expansion capacity were evaluated. Direct and indirect gains with selection were predicted on expansion capacity assessed in hot air and Metric Weight Volume Tester popcorn makers. The gains observed were calculated to evaluate the efficiency of the reciprocal recurrent selection. The covariance analyses showed genotypic variability in the populations. When compared to the commercial controls, the S0xS0 hybrids were inferior in quality and equivalent in productivity; and the S1xS1 hybrids were equivalent in both traits. The observed gain in expansion capacity was substantial (around 4 mL g-1) and higher than the predicted gain (2.8 mL g-1). The reduction observed in productivity was not relevant. Reduction in the genotypic variability was verified for expansion capacity. The reciprocal recurrent selection method was efficient in producing S1xS1 hybrids superior to S0xS0 hybrids.

    Abstract: Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time‐consuming, especially in the highly diverse tropics. We aimed to provide a comprehensive repository of available flower–invertebrate interaction information for the Atlantic Forest, a South American tropical forest domain. Data were obtained from published works and “gray literature,” such as theses and dissertations, as well as self‐reports by co‐authors. The data set has ~18,000 interaction records forming 482 networks, each containing between one and 1061 interaction links. Each network was sampled for about 200 h or less, with few exceptions. A total of 641 plant genera within 136 different families and 39 orders were reported, with the most abundant and rich families being Asteraceae, Fabaceae, and Rubiaceae. Invertebrates interacting with these plants were all arthropods from 10 orders, 129 families, and 581 genera, comprising 2419 morphotypes (including 988 named species). Hymenoptera was the most abundant and diverse order, with at least six times more records than the second‐ranked order (Lepidoptera). The complete data set shows Hymenoptera interacting with all plant orders and also shows Diptera, Lepidoptera, Coleoptera, and Hemiptera to be important nodes. Among plants, Asterales and Fabales had the highest number of interactions. The best sampled environment was forest (~8000 records), followed by pastures and crops. Savanna, grasslands, and urban environments (among others) were also reported, indicating a wide range of approaches dedicated to collecting flower–invertebrate interaction data in the Atlantic Forest domain. Nevertheless, most reported data were from forest understory or lower strata, indicating a knowledge gap about flower–invertebrate interactions at the canopy. Also, access to remote regions remains a limitation, generating sampling bias across the geographical range of the Atlantic Forest. Future studies in these continuous and hard‐to‐access forested areas will yield important new information regarding the interactions between flowers and invertebrates in the Atlantic Forest. There are no copyright restrictions on the data set. Please cite this data paper if the data are used in publications and teaching events.
