Application of molecular and biotechnological techniques in plant disease management: A review

Plant diseases are a major challenge in crop production. They are caused by nematodes, bacteria, fungi, viruses as well as plant nutritional factors. Diseases interfere with the normal physiological and metabolic processes of plants. This results in various effects including wilting, stunting, yellowing and death of plant tissues and organs. Crop losses due to diseases manifest in form of reduced yield, poor quality...

In vitro inhibitory potentials of aqueous and ethanol extracts of Hyptis suaveolens on fungi associated with postharvest spoilage of Brassica oleracea

The inhibitory potential of Hyptis suaveolens leaf and root extracts on fungi associated with postharvest spoilage of cabbage (Brassica oleracea var. capitata) was examined. Collection of diseased cabbage was done in sterile sample bags . Isolation of fungi was carried out by inoculating small sections of diseased tissues excised from the cabbages unto Petri-dishes containing Acidified Potato Dextrose Agar (APDA)....

Technological properties and sugar tolerance performance of palm wine yeasts isolated from parts of Nsukka, Nigeria

The ability of yeasts to survive and produce significant ethanol in high sugar medium and high ethanol environment is essential for the use of such yeasts in industrial and edible ethanol production. Four Saccharomyces spp. strains () isolated from palm wine and an industrial strain were studied in high glucose medium for ethanol production and ability to survive in high sugar medium. Saccharomyces cerevisiae...

Genetic variability, heritability and expected genetic advance of yield and yield related traits in common bean genotypes (Phaseolus vulgaris L.) at Abaya and Yabello, Southern Ethiopia

This experiment was conducted to evaluate 36 common bean genotypes including seven released varieties to generate information on the extent of genetic variability, heritability and expected genetic advance of yield and yield related traits. The field experiment was conducted in 2015 at two locations (Abaya and Yabello) and genotypes were planted in triple lattice design. Data were collected on yield and important...
