| Abstract: The objective of this work was to evaluate the adaptability and multi-trait stability of wheat (Triticum aestivum) genotypes according to the phenotypic index of seed vigor (PIV). Thirty wheat genotypes were grown in seven environments in the state of Rio Grande do Sul, Brazil, during one crop season. In each environment, a randomized complete block design with three replicates was used. The PIV was elaborated from the following traits: first germination count, germination percentage, accelerated aging, and electrical conductivity. The evaluated phenotypic index makes it possible to define macroenvironments for the production of wheat seeds with high physiological potential and to understand the implications of the genotype x environment... |

| The aim of this study was to evaluate changes in canola yield components and seed physiological quality in response to different sowing densities. The study was made in a greenhouse at the REIPESOL Company Technological Center, Madrid - Spain, with the commercial "Toccata" hybrid variety. The initial sowing density was 360,000 plants/ha and the plant population was later thinned down to include treatments of 250 and 180 thousand plants/ha. Harvested seeds were sent to the Seed Technology Center Laboratory (CATES) at the Madrid Polytechnic University (UPM) to evaluate changes in plant architecture and yield components, as well as the seed physiological quality of different plant parts. Results demonstrated that canola plants showed changes in morphology and... |

| This paper examines the performance of the Indian seed system in the context of high volume, low value seed, using the case studies of potato and groundnut. In theory, public sector should be able to address seed needs of farmers growing these crops. However, the ability of the public sector is constrained by a number of institutional and technical factors, and farmers largely depend upon traditional sources of seed. The traditional sources meet more than two-thirds of the total seed demand , and the rest is met by the formal seed system, mainly public seed agencies. Most of the farmers buy fresh seed for quality reasons, and only 12-15 percent farmers purchase seed to change variety. In potato, technological innovation provided options to enhance... |

| El tomate de cáscara se explota en Sinaloa (México) desde hace 20 años y su importancia se incrementó en la última década. Existe muy poca información sistematizada del manejo y potencial productivo de diferentes variedades. Aquí se estudió el desarrollo de fruto y semilla, y la calidad de esta, en cinco variedades (Querétaro, Rendidora, Mahone, Orizaba, Carriceño) sembradas en dos fechas (FS1: 6 de septiembre y FS2: 16 de octubre de 2008). Las variedades Querétaro y Mahone tuvieron en promedio un fruto más largo (37 y 34 cm), ancho (43 y 40 cm) y pesado (38 y 34 g, respectivamente), lo que llevó a que Querétaro tuviera el rendimiento de fruto (RendF) más alto (53 t ha-1). El mejor desarrollo de cultivo se observó en FS1, debido a que en FS2 se presentó un... |

| The objective of this work was to evaluate the width and length incidence in a single seed fraction of oat [Avena sativa (L.)] cv. Cristal. The seeds were selected by a mechanical divider and by hand, and their correspondence to radiographic images in seeds with glumes and their caryopses. The width and length of the seeds with glumes and their caryopses were measured with electronic calliper, and their weight, with precision balance. Radiographic images of seeds with glumes were taken with an X-ray experimental equipment. The analyst selected seeds with glumes by the width and by the length previously determined and so with more weight, than that obtained by hand selection was slightly narrower, larger and lighter. The presence of the glumes masked the... |

| No período de 1980 a 1984, foi conduzida, em Londrina, PR, uma serie de cinco experimentos, objetivando quantificar o efeito de diferentes populações de percevejos sobre o rendimento e seus componentes, as características agronômicas e a qualidade da semente de soja. A cultivar utilizada foi a UFV-1, por sua característica de ciclo longo, constando o experimento de seis tratamentos que previam a aplicação de endosulfan (525 g i.a./ha) quando a população de ninfas grandes e adultos de percevejos (Nezara viridula, Piezodorus guildinii e Euschistus heros) atingisse 1, 2, 4 ou 6 exemplares por metro de linha. Adicionalmente, havia um tratamento com aplicação de inseticida em caráter preventivo, de forma a impedir o surgimento de percevejos nestas parcelas, e... |

| The objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that... |

| Improved grasses planted for forage are increasing in demand throughout Thailand due to the increasingnumber of cattle. New varieties are being introduced in response to new demands. Brachiaria grasses, especially the hybrids, are gaining popularity because of their good yields and high quality. However, seed production of the brachiaria hybrids is difficult. The objectives of this experiment were to find out the appropriate rate (0, 20, 40, or80 kg/ha N) of N fertilizer (46-0-0) for growth, seed yield and quality of three lines of brachiaria hybrid (Mulato II,BR02/1752, and BR02/1794). This experiment composed of a field trial and laboratory tests and all were conducted at the Faculty of Agriculture, Ubon Ratchathani University, Thailand from May 2009 to... |
