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...

Delivering Seeds of 'Orphan' Crops: The Case Studies of Potato and Groundnut in India AgEcon
Pal, Suresh; Singh, Harbir; Mathur, Prasoon.
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...

Description of a pure seed fraction of oat through usual evaluations and radiographic images PAB
Craviotto,Roque Mario; Yoldjian,Ana Maria; Salinas,Adriana Rita; Arango,Miriam Raquel; Bisaro,Vilma; Maturo,Hernán.
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...

VILLAS BOAS, G. L.; GAZZONI, D. L.; OLIVEIRA, M. C. N. de; COSTA, N. P. da; ROESSING, A. C.; FRANCA NETO, J. de B.; HENNING, A. A..
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...

Effect of inoculation associated to leaf sprayed Co+Mo on the yield and grain nutrients in common bean (Phaseolus vulgaris L) BABT
Berton Junior,João Francisco; Santos,Julio Cesar Pires; Coelho,Cileide Maria Medeiros; Klauberg Filho,Osmar.
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...

Evaluation of lignin content of soybean seed coat stored in a controlled environment Rev. bras. sementes
Krzyzanowski,Francisco Carlos; Franca Neto,José de Barros; Mandarino,Jose Marcos Gontijo; Kaster,Milton.
Breeding soybean for high seed quality is an important approach for developing cultivars for tropical regions, and the lignin content in the seed coat is one of the screening parameters for this trait. Considering that many breeding lines are evaluated in each growing season using the presently recommended method for lignin determination, a long period is required for the evaluation of the whole breeding program. This time limitation may influence lignin content assessment, if lignin is degraded during storage. This research reported was designed to determine whether lignin was degraded in the seed coat of soybean seed cultivars stored for one year in a controlled environment (10°C temperature and 50% air relative humidity). Seeds of 12 selected soybean...
