27. Classification of physiological races of Fusarium oxysporum f. sp. phaseoli in common bean
Fusarium wilt, caused by Fusarium oxysporum Schlecht. f. phaseoli Kendrick and Snyder (FOP), is a major disease of common bean, causing large economic losses. Genetic resistance is one of the main mechanisms of pathogen control, and knowledge of the physiological variability is fundamental in breeding for resistant cultivars. Thus, a method of pathogen class

28. Recurrent mass selection for upright plant architecture in common bean
Plant with a more upright architecture offers many advantages to farmers. Recurrent mass selection (RS) programs for carioca type common bean have been implemented for the purpose of obtaining new lines that will generate the high yields that are associated with upright plant archi tecture. This study aimed to assess the efficiency of recurrent mass selectio

29. Diallel among soybean genotypes with high oil content and resistance to sudden death syndrome
The objective of this work was to use a partial diallel to evaluate the combining ability of 14 soybean genotypes and recommend superior combinations. Seven of the genotypes had high oil yield; other seven exhibited tolerance to sudden death syndrome and they generated 49 hybrids in a diallel cross without reciprocals. F2plants of each cross and the parents

30. The sarsaparilla market in the state of São Paulo (Brazil) and the challenges of cultivation
This study aimed to present information about the sarsaparilla sold in establishments in the state of São Paulo, Brazil, assess the genetic diversity of Smilax brasiliensis Spreng., Smilacaceae, and examine the growing conditions and productivity of five species of Smilax. The amount of sarsaparilla sold per month at most pharmacies was 0.4 kg on average. H

31. Virulence and molecular characterization of Costa Rican isolates of Rhizoctonia solani from common bean
Web blight is one of the main diseases that affects bean (Phaseolus vulgaris) cultivation. It infects diverse organs at any growth stage of the plant and can be present at different altitudes in a humid tropical climate. The causal agent of this disease is Thanatephorus cucumeris in its sexual stage and Rhizoctonia solani in the anamorph. The objective of th

32. Carbohydrate production and transport in cotton cultivars grown under boron deficiency
An adequate supply of boron (B) is required for the optimal growth and development of cotton (Gossypium hirsutum L.) plants, but the low phloem mobility of B limits the possibilities of correcting B deficiency. There are indications that different cotton cultivars could have different responses to B deficiency. The differences in responses of cotton cultivar

33. Genetic parameters of agronomic characters in Panicum maximum hybrids
This study was carried out with the objective of estimating the genetic parameters of agronomic traits in Panicum maximum hybrids. Genotypes obtained from the crosses between the sexual plants S10 and S12 and cultivars Tanzania and Mombasa were evaluated. The design was an incomplete blocks design with two replicates (clones) and 33 blocks. Each block was co

34. Diversidade genética de isolados do fungo Sporisorium scitamineum analisada através de fingerprinting da região telomérica / Genetic diversity of isolates of the fungus Sporisorium scitamineum analyzed by fingerprinting the telomeric region
The genetic diversity of Sporisorium scitamineum, the sugarcane smut agent, was characterized in a 14 isolates collection. The isolates were obtained from various sugarcane growing areas and RFLP of the telomeric region was used as molecular marker, compared with AFLP. Teliospores were collected from the whip of infected plants. Teliospores are diploids and

35. ÍNDICE RELATIVO DE CLOROFILA PARA O DIAGNÓSTICO DO ESTADO DE NITROGÊNIO EM HÍBRIDOS DE MILHO
Nitrogen (N) is the nutrient that contributes the most to increase productivity of corn hybrids. For this reason, the main objective of this study is to determine the relative chlorophyll index (RCI), in different leaves and phenological stages, aiming diagnosing N state in corn hybrids according to the N doses applied in coverage, correlating them with the

36. Resposta de genótipos de citros à leprose e variabilidade genética da ORF p29 do vírus da leprose dos citros C (CiLV-C) / Response of citrus genotypes to leprosis and genetic variability of ORF p29 from Citrus leprosis virus C (CiLV-C)
Viruses have, potentially, broad genetic variability because of their need to adapt to several changes that they are exposed to. Therefore, genetic variability is essential for their survival; it is the first step to adapt to a new host, to break resistance down, to change symptoms and virulence, which justifies the interest in studies in this area. These st
