| The Capsicum breeding has been developed with emphasis in bell pepper (Capsicum annuum) and few studies are available in other species, especially C. baccatum, which has potential use not only as disease resistance source but also in obtaining new genotypes suitable for farmers' production. In the present work, the combining ability of ten C. baccatum hybrids, along with their five parentals, were tested considering 12 agronomic traits. The hybrids were produced from a complete diallel without reciprocals and assessed in greenhouse conditions, in Campos dos Goytacazes, Rio de Janeiro state, Brazil, during the period July to December 2009. The experimental design was a randomized block with three replications and the following agronomic traits evaluated:... |

| The objective of this study was to evaluate the physicochemical characteristics of parents and experimental hybrids of net melon improvement program developed in the Universidade Estadual Paulista (UNESP), in Jaboticabal, São Paulo state, Brazil. Six net melon lineages (Jab-3, Jab-7, Jab-11, Jab-18, Jab-9, and Jab-20), belonging to the breeding program of melon from the UNESP were used and all their hybrid combinations as well as their reciprocal crosses. We used the randomized blocks design, with three replications and 38 treatments. From these 38 treatments [six lines, 15 hybrids, 15 reciprocal crosses and two commercial cultivars (Bônus nº2 and Louis)] we evaluated following physicochemical characteristics: fruit mass, pulp thickness, fruit coat... |

| ABSTRACT In the sweet corn breeding, the selection of superior genotypes should consider many traits simultaneously. The best strategy to select traits simultaneously is through selection indexes. This study aimed to compare the efficiency of different selection indexes based on characteristics with direct effect on grain yield in segregating sweet corn populations. Eighteen traits were evaluated in eight sweet corn genotypes on generation F3. Data were submitted to analyses of variance and path coefficient analyses. We compared the direct and indirect selection and the following indexes: base, classical, desired gains and genotype-ideotype distance. According to path coefficient analyses, the traits which showed a direct effect about grain yield (GY) were... |

| ABSTRACT: Mango (Mangifera indica L.) is one of the most important tropical fruits cultivated in Brazil with area higer than 70 thousand hectares, production of 970 thousand tones. However, it was exported only 13,4% of this production, which is equivalent to 130 thousand tones, in 2003. Mango production and exportation are mostly developed at tropical Semi-arid condition in Northeast Brazil, which concentrated 80% on a cultivar only, Tommy Atkins. This is very dangerous though if a severe disease occrus at this specific genotype, mango production may have a strong loss and, or the whole Brazilian mango area might be destroyed. This cultivar has some negative characteristics, such as high susceptibility to mango malformation and pulp breakdown as well as... |

| RESUMO: A cultura do abacate (Persea americana Mill), no Bioma Cerrado, apresenta grandes possibilidades uma vez que as condições ecológicas favorecem seu desenvolvimento. É grande a carência de informações sobre o comportamento dessa fruteira na região, no entanto, são encontradas plantas vegetando muito bem, sendo a maioria desse material originário de pés-francos, ou seja, não reproduzem as características das cultivares. A introdução dos "acessos" permite a obtenção de cultivares adaptadas à região. O fato de serem poucas as cultivares exploradas na região, o período de comercialização do produto é muito estreito, todavia, o abacate permite a seleção de cultivares com vistas a escalonar a produção durante todo o ano. O objetivo deste trabalho foi... |

| O objetivo do trabalho foi caracterizar acessos de mandioca com coloração da polpa da raiz branca, creme, amarela e rosada, por meio de descritores morfológicos. O experimento foi conduzido entre 2006 e 2007, em área experimental da Embrapa Cerrados. Foram avaliados,por meio de 33 descritores morfológicos, 16 acessos de mandioca mantidos no Banco Regional de Germoplasma de Mandioca do Cerrado (BGMC), sendo 1 acesso com coloração da polpa da raiz branca, 2 com coloração da polpa da raiz creme, 4 com coloração da polpa da raiz rosada e 9 com coloração da polpa da raiz amarela. Entre os 33 caracteres qualitativos avaliados, 27 (82 %) apresentaram variabilidade, o que revela a existência de ampla divergência morfológica e a eficiência desses marcadores na... |
