Condition: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | Sorghum production constraints vary from region to region within Ethiopia. However, drought and striga are reported to be important sorghum production constraints in the north and northeastern parts of the country. Stiriga hermonthica, the dominant striga species, is the most severe in the highly degraded north, northwestern and eastern parts of the country, viz. Tigray, Wollo, Gonder, Gojam, North Shewa and Hararghe. Over 80% of sorghum in Ethiopia is produced under severe to moderate drought stress conditions. In spite of biotic and abiotic stress tolerance, it is largely affected by genotype × environment interaction (GEI), making it difficult and expensive to select and recommend new sorghum genotypes for different environments. Hybrids have been found better suited than varieties to such stress environments as a result of earliness, better adaptation and stability. …

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Information on genetic gain achieved over time from a breeding program is absolutely essential to develop effective and efficient breeding strategies by assessing the efficiency of past improvement works in genetic yield potential and suggest on future selection direction to facilitate further improvement. The regression analysis demonstrated an increase in estimated average annual rate in grain yield potential of 27.5 and 29.46 kg ha-1 year-1 with an annual relative genetic change of 0.78 and 1.01% yr-1 at Melkassa and Mieso, respectively. The results signify important efforts of the past breeding program and, also, absence of plateau which, in turn, imply the potential for further improvement in grain yield of sorghum. In general, this book provides a comprehensive explanation and appraisal information generated from the genetic improvement on released sorghum varieties in Ethiopia could serve as baseline to generate reliable information regarding genetic improvement and morpho-physiological characters associated with genetic progress and crop breeding programme.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Tef is an ancient crop in Ethiopia, and the country is considered to be the center of both origin and diversity for the species (Vavilov, 1951). The grain of Teff still provides over two-thirds of the human nutrition in Ethiopia; it is relatively unknown as a food crop elsewhere. Tef grain is gluten free, and is a good our source for segments of the population suffering from gluten intolerance or Celica's disease (Spaenij-Dekking et al., 2005). It has adaptive characteristics similar to other crops grown by early civilizations. Ecologically it can be cultivated under a wide range of environmental conditions such as on marginal soils under water logged to drought conditions. Beside, Tef generally suffers less from biotic stresses compared to most other cereal crops grown in Ethiopia and it contains high levels of proteins and mineral (Seyfu, 1993). It can produce a crop in a relative short growing season and will produce both grain for human food and fodder for livestock. The grain is either white or a very deep reddish brown in color. Now a day in the United States, Teff grain as being marketed as a health food product, or used as forage for livestock (Goerge 1991).…
