Phenotypic and genetic characterization of selected Kenyan groundnut (Arachis hypongaea L.) varieties

Groundnuts are among the principle economic oilseed largely cultivated in warm regions of Kenya and contribute to domestic food security and cash revenue. The study aimed at evaluating genetic diversity and phenotypic characterization of groundnut varieties grown in some parts of Kenya. Six varieties (ICG83708, ICGV99568, CG7, ICGV12991, RV and Chalimbana) obtained from KALRO (Kakamega) based on quality traits. Seeds...

Evaluation of sugar beet monogerm O-type lines for salinity tolerance at vegetative stage

Increased production of sugar beet under rainfed conditions on saline–sodic soils in the Iranian areas highlights the importance of salt tolerant varieties. Screening of genotypes for salinity tolerance is difficult in field due to heterogeneity of physical and chemical properties of soil. In order to evaluate the salinity tolerance of 21 sugar beet monogerm O-types lines, a pot experiment was conducted using a...

Diversity and genetic structure in natural populations of Croton linearifolius (Euphorbiaceae) based on molecular markers

Croton linearifolius Mull. Arg, an endemic species of Brazil, has insecticidal activity proven. To the detriment of its importance as a natural resource, the studies of this species are incipient, as well as the strategies applied to its management and conservation. The diversity and genetic structure in 61 individuals of C. linearifolius collected in the National Forest Contendas do Sincorá (NFCS) were...

Evaluation of different fungi and bacteria strains for production of cellulases by submerged fermentation using sugarcane bagasse as carbon source: Effect of substrate concentration and cultivation temperature

Cellulases (enzymes of great potential in biotechnology) are currently of interest due to their applicability in the hydrolysis of cellulose from lignocellulosic materials, producing fermentable sugars for alcohol production. The great demand for efficient enzymes is the driving force to prospect new cellulases-producing microorganisms, as well as to optimize the enzyme production step. Many variables can be optimized...
