Abstract: Common bean (Phaseolus vulgaris L.) is one of the most important legumes and is high in protein, low in fat, and rich in vitamins and dietary fiber. The regular consumption of common bean can reduce coronary heart disease, type II diabetes, and cancer. Assessing the causes and magnitude of variation is the key to success in crop improvement program. This study was therefore conducted to determine the nature and magnitude of genetic variability and association of yield and yield rel...
Abstract: The study was carried out to assess the genetic variability and association Using Morphological Markers among faba bean genotypes. Faba bean have a long tradition of cultivation in old world agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. Utilizing a selection of faba bean that have variation in their morphological attributes. Twelve faba bean genotypes were evaluated in randomized complete block design (RCBD) with three replicati...
Abstract: This study was conducted in HU poultry farm with the objective of evaluating and comparing production and reproduction performances, heterosis and combining ability up to the age at first egg laying for pure, straight and reciprocal crosses of Koekoek and White Leghorn poultry breeds. Two pure breeds of chickens namely Koekoek (KK) and White Leghorn (WH) were used in 2×2 diallel crossing experiment by AI mating system. From a total of 172 chickens (12 cocks and 160 hens), 3 cocks ...
Abstract: In Ethiopia, a lot of improved bread wheat varieties have been released; however, the released varieties from different research centers were not tested at Gitilo Dale, Western Ethiopia for their genetic variability and association of traits in bread wheat varieties. In view of this, the study was conducted in Western Ethiopia at Gitlo Dale, Horroo Guduruu Wollega, with the objectives of determining the extent of genetic variability and association of traits with grain yield and th...
Abstract: Outbreaks of emerging and re-emerging tick-borne pathogens are becoming more frequent worldwide. Surveillance is critical to improve our understanding of pathogen diversity and their tick vectors. This will elucidate disease transmission dynamics that can inform the development of better disease prevention and control strategies. A total of 4,324 questing ticks (209 adult ticks, 586 nymphs and 3,502 larvae) were collected from six sites in Kenya‟s Shimba Hills National Reserve (S...
Abstract: Bacteria of the genus Xenorhabdus are entomopathogens that produce insecticidal protein toxins against a wide range of insects. The main proteins involved are the Xenorhabdus protein toxins (Xpts), categorized as class A, B and C. They work best as a complex, though individually, XptA has been found to be more potent against some insect pests such as Pieris brassicae and Heliothis virescens. The maize weevil (Sitophilus zeamais) and the larger grain borer (Prostephanus truncatus) a...
Abstract: Xenorhabdus spp. (Enterobacteriaceae) are endosymbionts of entomopathogenic nematodes from the Steinernema genus. They cause insect mortality by producing potent insecticidal toxin complexes composed of XptA1, XptA2 (class A), XptB1 (class C) and XptC1 (Class B) proteins. However, the use of only the bacterium as a biopesticide is limited as they depend on their nematode hosts for survival in the environment. The XptAs exhibit different spectra of activity, requiring XptB1 and XptC...
Abstract: Aphids are the major pests of vegetables leading to a significant yield loss in African indigenous vegetables including amaranth and nightshades. Information on the types of aphids that infest these vegetables and their genetic diversity in Kenya and Tanzania is scanty. This is an important diagnostic component in developing management strategies such as integrated pest management and early detection and control of invasive species. This study used a fragment of the mitochondrial c...
