GGE Biplot for Grain Yield and, Estimation of Variance Components and Heritability of Agronomic Traits for Early Maturing Sorghum (Sorghum bicolor L. Moench) Genotypes

Genotypes are grown in trials across multiple locations and years, known as multi-environment trials (METs). Genetic performance across these locations is measured as genotype by environment interaction (GEI). Combined analyses of variance showed significant differences for genotypes, environments and GE. The genotypes G54, G76, G52 and G41 were early flowering and high yielding, and possessed other desirable agronomic...

Cold tolerance and amino acid content of overwintering eggs in Gomphocerus sibiricus L. (Orthoptera: Acrididae)

This study investigated the changes in cold tolerance capacity and amino acid content in the eggs of Gomphocerus sibiricus. The super-cooling points (SCPs) and freezing points of G. sibiricus eggs were measured monthly using thermocouples. The water content was determined via oven-drying, and the amino acid content was measured with an amino acid automatic analyser. The SCPs of G. sibiricus eggs initially increased and...

Extraction, Isolation and Characterization of Pure Compounds from Prosopis juliflora, and Determination of the Effects of the Compounds on Groundnut Aphids

Natural products from medicinal plants, either as pure compounds or as standardized extracts, provide unlimited opportunities for different purposes. Botanical preparations of medicinal plants for insecticidal usage contain various types of bioactive compounds. The focus of this paper is the botanical evaluation of stem bark, seed and leaf extracts of Prosopis juliflora for their insecticidal effect against groundnut...

Forward genetics in smut fungi: Creation of mating defective mutants of Sporisorium scitamineum for gene discovery

Sexual phases among pathogenic fungi are major determinants of morphological transitions linked to virulence. The sugarcane smut fungi, Sporisorium scitamineum, are an obligate bitrophic pathogen, whose molecular basis of sexual mating is poorly understood. Here we report the creation of a library of mating-defective mutants of S. scitamineum using Agrobacterium mediated random insertional mutagenesis in the quest to...

Effect of 2, 4-dichlorophenoxy acetic acid and naphthelene acetic acid concentrations on callogenesis for in vitro regeneration in selected sugarcane varieties

This study investigated the effect of 2,4-dichlorophenoxyacetic acid (2, 4-D) and naphthalene-1-acetic acid (NAA) concentrations on callus induction and shoot regeneration in three sugarcane varieties: CO945, CO421, and N14. Young leaf spindle explants were cultured on Murashige and Skoog (MS) basal medium supplemented with 2, 4-D (0.0, 2.0, 2.5, 3.0, 3.5 and 4.0 mg L-1) and NAA (0.0 and 1.0 mg L-1). Experiments were laid...
