“…Even today, it is evident that Ethiopian farmers are practicing traditional farming and their indigenous knowledge will continue and be passed to the coming generations unless some radical interventions are introduced. Ritualistic, symbolic and religious associations with bioresources are more deep-rooted in cultures, than the material uses of genetic resources (Jain, 2000). The exploitation or protection of bioresources, which is selective, influences the distribution, abundance and consequent availability, which in turn compels modification or substitution in plant or animal-man relationship.…”

The aim of the study was to document wheat landraces that were and and Dandi districts, West Shewa, Ethiopia; and to investigate the extent of genetic loss and its causes. Survey was carried out in three Peasant Associations of Ambo District and four Peasant Associations of Dandi District from 2007 to 2008. Three to five farmers' group per Peasant Association containing 5 to 12 individual farmers per group were used for group discussions from September to December was conducted using semi-structured questionnaire prepared by researcher from August to October 2008. In total 20 diverse tetraploid wheat landraces were identified in the study areas. However, presently 4 to 5 landraces are cultivated. Genetic erosi 62% in Ambo and Dandi district, respectively. The landraces differ concerning morphology, adaptation and end-uses. Some landraces exhibit broad adaptation that enables them to be cultivated in a wider area over different districts. Specific adaptation to various soil conditions, e.g. water logging and poor soil fertility, and short rainy season play key roles for the predominant cultivation of specific landraces over others in sensitive environmen Preferences for end-use products and market prices also display major impacts on the continuous cultivation of tetraploid wheat. The causes for the loss of landraces varieties were expansion of improved bread wheat varieties, low soil fertility and poo landraces, and shorter rainy season. Among the available varieties, predominantly grown in both districts, due to its higher price in the market for its brewing quality. Diverse farmers' indigenous knowledge supported continu conservation of landrace varieties.

“…Implicit in this goal is the identification of factors that influence land use practices, as well as which species are used. Home garden research differs from much ecological and cultural anthropological research in that it requires an understanding and documentation of cultural, social, and economic factors critical in determining management practices and an understanding and documentation of the role of ecology and individual species' taxonomy and growth requirements (Alcorn 1981, Lamont et al 1999, Jain 2000. Thus, home garden research exists in a multidisciplinary zone among ecology, sociology, anthropology and economics in its goal to assess the many factors influencing one tract of land.…”

“…Thus, diverse cultures in a region apply distinct folk-scientific and aesthetic criteria to the selection of plants (Jain 2000, Nabhan 1985. Nabhan (1985) and Cleveland and coauthors (1994) have identified three reasons why traditional varieties of plants are valuable to conserve:…”

Chemical composition, protein fractionation, essential amino acid potential and antimetabolic constituents of an unconventional legume, Gila bean (Entada phaseoloides Merrill) seed kernel

Physical characteristics of pods and seeds, proximate composition, different protein fractionation, SDS-PAGE analysis of proteins, amino acid composition, starch content, fatty acid pro®les and various antimetabolic substances of Gila bean (Entada phaseoloides Merrill) were studied. The pod length and the number of seeds per pod ranged from 55 to 90 cm and from 5 to 11 respectively. The kernel comprised 66.1% of the seed weight (18.41 AE 1.14 g). The seed kernels contained 256.7 g kg À1 crude protein, 108.1 g kg À1 lipid, 27.3 g kg À1 ash and a high content of carbohydrate (585.7 g kg À1 ). The levels of potassium, phosphorus, zinc and iron were similar to those in conventional pulses. Among the different protein fractions of seed kernels, albumins constituted the major storage proteins (69.7%). The kernel proteins were rich in essential amino acids, particularly sulphur-containing amino acids, and their values appeared to be higher than the FAO/WHO (1990) reference protein for a 2±5-year-old growing child and soybean, and comparable to hen egg. Seed kernel lipids contained high levels of unsaturated fatty acids, oleic and linoleic acids, which accounted for 83% of the total fatty acid recovered. The kernel exhibited high trypsin and chymotrypsin inhibitor activities (96.65 mg TI g À1 and 30.02 CIU mg À1 sample respectively) in addition to containing phenolics, phytic acid, lectins and oligosaccharides. Another major toxic constituent was identi®ed as a group of triterpenoid saponins (3.21%), which had high haemolytic activity (HeU) against cattle erythrocytes and caused high mortality in ®sh. The in vitro digestibility of the kernel protein was low (67%).
