Spatial variation in the micro-minerals and ß-carotene concentration in four varieties of plantain
Nutrition plays a vital role in growth, development and the prevention of possible nutrient-deficiency diseases that may cause permanent health risks in the later stages of life. Due to this, the concentrations of iron, zinc, copper, manganese and β-carotene in four varieties of plantain were investigated in this study. The relationship between the micro-minerals in the fruit, the sampling location and soil were...

Evaluation of maize germplasm for resistance to maize chlorotic mottle virus and sugarcane mosaic virus: The casual agents of maize lethal necrosis disease
In Kenya, at national policy level to the individual household level, food security is synonymous to maize productivity and availability. However, the productivity of maize is affected majorly by maize lethal necrosis disease (MLND) that was first reported in Kenya in 2011. MLND results from co-infection between maize chlorotic mottle virus (MCMV) and any cereal-infecting viruses in Potyviridae family particularly...

Radio-Sensitivity of four selected rice (Oryza sativa L.) varieties in Kenya, as a pre-requisite for mutation breeding
Radio-sensitivity test informs the optimal irradiation dose for use in mutation breeding. In this study, four rice varieties (Basmati 217, Basmati 370, ITA310, and Komboka) were irradiated with gamma-ray doses ranging from 0 to 500 Gy, to examine their morphological responses at the seedling stage, and estimate their optimal doses. Two experiments were carried out at varied time points between March and May 2022. In the...
