The genetic variability of 22 protein loci was investigated in two sheep flocks: 22 females Romney Marsh and 124 animals derived from crossbreeding between Romney Marsh and Merino Booroola, reared by the Brazilian Agricultural Research Corporation (Empresa Brasileira de Pesquisa Agropecuária -EMBRAPA, Bagé, RS, Brazil). Eight loci were polymorphic; the others showed no variation. The usefulness of the eight plymorphic systems (Cat, DIA I, EP-1, EsA, HbB, ME, Tf, and X Prot.) in parentage tests was analyzed. The probability to find two random identical animals in each breed was estimated as 1:1000. The efficiency of these proteins for exclusion of one of two possible sires in parentage tests was about 77% both for Romney Marsh and Romney/ Booroola flocks. Although parentage tests in sheep have not been enforced in Brazil up to now, the establishment of this technique is important for the prevention of non-paternity on the excellent rams.

New Cultivars

In forty years of genetic breeding of wheat, Embrapa (Brazilian Agricultural Research Corporation) has developed over a hundred new cultivars for different regions of Brazil. Information regarding identification of these cultivars is often requested from Embrapa breeders. Data on year of release, name of pre-commercial line, the cross made, and the company unit responsible for indication of the cultivar are not always easily accessible and are often scattered throughout different documents. The aim of this study was to conduct a historical survey of all the wheat cultivars released by Embrapa, aggregating the information in a single document. Since 1974, Embrapa has released 112 wheat cultivars, including 12 by Embrapa Soybean - CNPSo (Londrina, PR), 14 by Embrapa Cerrado - CPAC (Brasília, DF), 9 by Embrapa Agropecuária Oeste - CPAO (Dourados, MS), and 77 by Embrapa Wheat - CNPT (Passo Fundo, RS).

Resources Conservation

SUMMARYThe Brazilian Agricultural Research Corporation (EMBRAPA), through the National Research Centre for Genetic Resources and Biotechnology (CENARGEN), created the National Research Programme for Genetic Resources in 1974, but at that time only plant resources were included. A few years ago, the need for conservation of animal genetic resources in Brazil became clear, and the lack of necessary documentation and evaluation was recognized. Finally, in 1981, CENARGEN decided to include animal genetic resources in its Research Programme. In the case ofcattle, actions are being taken to save the “Criollo” before it is too late as it is rapidly disappearing by indiscriminate crossbreeding. There is already considerable information on the “'local” livestock breeds, strains and varieties in Brazil. A number of these breeds, strains or varieties that are in danger of extinction have been identified, and are being documented and specifically evaluated, particularly to determine if they possess any unique or special inherited characteristic that would warrant their conservation. Until such evaluation is completed, steps are being taken to ensure preservation of these populations. More recently, the programme ineluded other species such as: buffaloes, pigs, sheep, goats, horses and donkeys.

Abstract: This article presents the experience of the Brazilian Agricultural Research Corporation (Embrapa) – a large state-owned company that plays an important global role in research, development, and innovation for tropical agriculture – in the planning and implementation of Open Access to scientific information in the context of a developing country. The aim of this initiative is to provide the necessary mechanisms to capture, store, organize, preserve, retrieve, and widely disseminate the scientific information produced by Embrapa and by agricultural research communities. This report concludes with a discussion of the obstacles encountered and the organizational features, cultural considerations, and political matters that facilitate open access implementation at Embrapa.

O entendimento dos efeitos climáticos e do uso do solo em conjunto é crucial para análise ambiental e prevenções de desastres naturais. O objetivo deste trabalho é analisar a vulnerabilidade à erosão hídrica do solo na bacia hidrográfica do rio Araguaia. Usou-se dados de precipitação (Agência Nacional das Águas); uso e ocupação da terra (Projeto MapBiomas); declividade (Instituto Nacional de Pesquisas Espaciais) e de solo (Empresa Brasileira de Pesquisas Agropecuária) no cálculo de mapas através do geoprocessamento para obter-se a representação da erosão hídrica do solo. A bacia hidrográfica do rio Araguaia caracteriza-se na maior parte por zonas de transição de estabilidade e vulnerabilidade, porém destaca-se as áreas estáveis nas proximidades da foz, regiões críticas á sudoeste (Rio das Mortes), nos limites (leste) do Alto Araguaia, nas partes sudeste e sudoeste do Baixo Araguaia. Na escala climática, a precipitação não apresenta riscos significativos. No entanto, o intenso uso e ocupação da terra na região foi a forçante que maior agravou a vulnerabilidade, principalmente em áreas (declives e solo) naturalmente instáveis. Assim, algumas cidades precisam estar em alerta para possíveis eventos erosivos.     Vulnerability to soil water erosion, Araguaia basin riverA B S T R A C TThe Understanding climate effects and land use together is crucial for environmental analysis and natural disaster prevention. The objective of this work is to analyze the vulnerability to soil water erosion in the hydrographic basin of the Araguaia river. Rainfall data (National Water Agency) was used; land use and occupation (MapBiomas Project); slope (National Institute for Space Research) and soil (Brazilian Agricultural Research Corporation) in the calculation of maps through geoprocessing to obtain the representation of soil water erosion. The hydrographic basin of the Araguaia river is characterized in the most part by transition zones of stability and vulnerability, however the stable areas in the vicinity of the mouth stand out, critical regions to the southwest (Rio das Mortes), on the (eastern) limits of the Alto Araguaia, in the southeast and southwest parts of the Lower Araguaia. On the climate scale, the rainfall does not present significant risks. However, the intense use and occupation of land in the region was the forcing that increased the risk, mainly in naturally unstable areas (slopes and soil). Thus, some cities need to be alert to possible erosive events.

This study was conducted at Agricultural Research Station (ARS), Vijayanagar, Jumla Nepal comprising fifteen genotypes of cold tolerance rice during regular rice growing season of high hill in 2015 in RCBD (Randomized Complete Block Design)  with three replications to observe genetic variability, correlation, heritability, genetic advance and clustering of genotypes in relation to yield and yield associated traits and selection and advancement of early maturing, high yielding, disease resistant, and cold tolerance genotypes for high mountain area. Analysis of variance revealed that all characters except number of panicle per hill were significantly different indicating presence of variation in genetic constituents. Phenotypic coefficient of variance (PCV) was higher than genotypic coefficient of variance (GCV) for all the corresponding traits under study indicating environmental influence for the expression of the traits. Higher PCV and GCV value were obtained in grain yield (Yld), number of grain per panicle (NGPP) and number of panicle per hill (NPPH). Higher heritability coupled with higher genetic advance (GA) was obtained in NGPP, NPPH and Yld, high heritability and medium GA was obtained in thousand grains wt (TGW), plant height (Pht) and panicle length (PL) indicating additive gene action indicating direct selection may be a tool for varietal development. Positive and significant correlation was obtained between all characters except DM and Pht, PL and PHT and TGW and PPH. Total three clusters were obtained in eighty percent euclidean similarity clustering indicating genetic closeness/distances among the genotypes. Culture 1 carries the superior five genotypes including NR-10638-B-B-4 and NR-10695-B-B-B. Int. J. Appl. Sci. Biotechnol. Vol 7(4): 445-452
