Loss of pod strings in common bean is associated with gene duplication, retrotransposon insertion and overexpression of PvIND
(2022-06)Fruit development has been central in the evolution and domestication of flowering plants. In common bean (Phaseolus vulgaris), the principal global grain legume staple, two main production categories are distinguished by ... -
Mathematical Modelling of Thin Layer Drying Kinetics of Onion Slices Hot-air Convection, Infrared Radiation and Combined Infrared- Convection Drying
(AENSI Publisher, 2014)Onion slices were dried in convection hot-air, infrared radiation and combined infraredconvection hot air dryers. A systematic experimental design was applied to analyse drying kinetics due to the effect of type of dryer, ... -
Mechanical expression of oil from grated and preheated coconut meat Botswana Journal of agricultural sciences
(2015)Coconut oil was extracted from grated coconut using a hydraulic pressing method after the coconut gratings were preheated at heating medium air temperature in the range of 30-90oC and heating durations ranging from zero ... -

Molecular genotyping of selected soybean (Glycine max L.) genotypes grown in different regions of East Africa
(2010)Soybean (Glycine max (L.) Merril) is one of the most popular pulses because of its protein content and nodulating ability. However, most farmers and researchers do not have sufficient genetic information of the genotypes ... -
Morphological and Molecular Characterization of Azolla Accessions in Kenya
(Tropical and Subtropical Agroecosystems, 2020-05)Background. Azolla Lam., a mosquito fern, is invasive in major rice growing Schemes in Kenya, where it clogs irrigation canals and forms dense mats in paddy fields. However, the species of Azolla has not been established. ... -
Morphological and Molecular Characterization of Toxigenic Aspergillus flavus from Groundnut Kernels in Kenya
(Hindawi, 2020-09)Pathogenesis of Aspergillus flavus on important agricultural products is a key concern on human health due to the synthesis and secretion of the hazardous secondary metabolite, aflatoxin. &is study identified and further ... -
Morphological Characterization of Five Newly Developed Lines of Arabica Coffee as Compared to Commercial Cultivars in Kenya
(ACADEMIC JOURNALS, 2010)Five new lines of Arabica coffee and two existing commercial cultivars planted in the field were characterized morphologically. The objective of this study was to determine the level of morphological variation within and ... -
