(University of Eldoret, 2021)Pig production in Kenya is characterized by lack of genetic performance parameters, crucial in setting up sustainable genetic improvement strategies. To partly address this situation, random regression (RR) models have ... -
Genetic identification of invasive walking catfish, Clarias batrachus, intermingled with African catfish, C. gariepinus, in South Africa
(African Journal of Wildlife Research 45(1): 55–62 (April 2015), 2015-04)Molecular genetic techniques were used to determine the identity of two catfish individuals that could not be identified as indigenous Clarias gariepinus after phenotypic analysis. The unidentified catfish were compared ... -
GENETIC LOCI FOR RESISTANCE TO BLAST (Pyricularia oryzae) POPULATIONS IN IRRIGATED RICE IN KENYA
(University of Eldoret, 2015)Rice (Oryza sativa) is the third most important food crop after maize and wheat in Kenya. Blast (Pyricularia oryzae) is one of the most destructive and widespread diseases of rice in Kenya but minimal research attention ... -
GENETIC STRUCTURE OF CRIMSON JOBFISH, Pristipomoides filamentosus (VALENCIENNES, 1830) POPULATION OF THE SOUTHWEST INDIAN OCEAN
(University of Eldoret, 2013)Crimson jobfish, Pristipomoides filamentosus is a commercially important tropical snapper. Their aggressive nature and relatively large size makes them more vulnerable to fishing gears. In addition it is vulnerable to ... -
