Report on the cost-benefit analysis for integrating new forage technologies in cattle production systems in Kenya and Ethiopia
https://hdl.handle.net/10568/115866
Abstract
This report presents the results of an economic evaluation of establishing new forage alternatives in cattle systems in Kenya and Ethiopia. In Kenya, we evaluated the inclusion (intervention scenario IN) of the grasses Panicum maximum cv. Maasai and Brachiaria hybrid cv. Mulato II, and in Ethiopia, Bachiaria hybrid cv. Mulato II and Brachiaria mutica. The evaluated…

Abstract
The International Center for Tropical Agriculture (CIAT) implemented Irrigated forage production and environmental interventions in Kilimanjaro and Tanga Regions of Tanzania. Four Districts (Siha, Hai in Kilimanjaro, Muheza and Mkinga in Tanga) were the main activity sites located for establishment of improved irrigated forage demo plots, where Brachiaria hybrid cv Cobra variety and Brachiaria hybrid cv Cayman varieties…

Report on sampling leaf tissue, DNA extraction and prepare for shipment for genotyping of two biparental populations to identify QTLs associated with Spittlebug resistance
https://hdl.handle.net/10568/115879
Abstract
Spittlebugs (Hemiptera: Cercopidae) are the major production limitation for Brachiaria grasses (Urochloa spp.) in the tropical America. Incorporate host-plant resistance to new hybrids is the most cost-effective and sustainable solution to overcome the great losses caused by this key pest. Identifying regions in Urochloa…

Report on quality estimation for selection purposes in 300 apomictic interspecific hybrids of the population Br19
https://hdl.handle.net/10568/115880
Abstract
The aim of this work was to estimate the nutritional value of 300 hybrids from Urochloa interspecific breeding program. Plant biomass was harvested and subjected to a bromatological analysis to evaluate crude protein, neutral and acid detergent fiber, and in vitro digestibility using standardized methods. A large proportion of the hybrids showed better nutritional values than…

Report on genotyping for identification of reproductive behaviour in Pm21 using marker assisted selection
https://hdl.handle.net/10568/115881
Abstract
Continuing with the implementation of the guinea-grass breeding scheme (M. maximus), a half-sibs population was formed through a factorial cross design. Using standardized protocols, the identification of the reproduction mode was carried out in the population of hybrids obtained (called Pm21) using the molecular marker p779 / p780. A total of 3,156 (44%) hybrids, from 6,820, showed…

Report on methodology for screening of spider mites resistance in a diversity panel
https://hdl.handle.net/10568/115882
Abstract
Spider mites attack is the most important limitation for improved Urochloa (syn. Brachiaria) crops in Eastern Africa causing up to 100% loss during the dry seasons. Two spider mite species have been previously identified in Kenya attacking brachiaria grasses: Tetranychus urticae (Koch) and Oligonychus trichardti (Meyer). Variation in the response of brachiaria genotypes to O. trichardti attack was…

Genotypic variation in drought resistance among Urochloa Hybrids (population Br15)
https://hdl.handle.net/10568/115900
Abstract
Previous research showed a correlation in the ability to uptake water from drying soil and shoot biomass production in Urochloa hybrids (Jimenez et al, 2016). The ability to uptake water in drying soil is associated with a larger and deeper root system in Urochloa grasses (Cardoso et al., 2015). Bearing that into mind, drought resistance in Urochloa grasses has been defined as the ability to produce more…
