 Abstract

The research was undertaken with the major objective to assess nature and magnitude of variability (PCV, GCV), degree of interrelationship among the yield and its attributing traits, heritability, genetic advance, and genetic advance as percentage of mean (GAM) as well as protein content in fourteen QPM genotypes for 15 different traits. The trial was conducted during summer planting condition 2018, at the field of Agriculture Botany Division, Khumaltar, Lalitpur in Randomized Complete Block Design with three replications. The result from the experiment, illustrated significant variations for most of the traits studied. Considering the variability traits, the range of Phenotypic Coefficient of Variability (PCV) analyzed was in between 3.39 to 24.08 % which clearly illustrates the extent of phenotypic variability present among the tested quality protein maize genotypes. In the same way, genotypic coefficients of variations ranged from 2.75 to 20.49 % for various traits studied. The highest Genotypic Coefficient of Variability (GCV) was observed for Leaf Area Index (LAI) with 20.49% followed by protein content with 19.84% and grain yield with 17.59%. The high heritability was observed for most of the traits studied except for cob girth and total kernels per cob. The high heritability coupled with high genetic advance as percent of mean was observed for LAI, grain yield, protein content and 1000 kernel weight. The phenotypic correlation study revealed that grain yield expressed significant positive association with LAI, plant and ear height, cobs per plant, cob length, cob girth, kernels/row as well as shelling percentage. The study illustrated the existence of wide ranges of variation for most of the traits for various QPM genotypes. Hence, improvement and selection of one or more of the major traits among various QPM genotypes would be of great importance at various aspects of plant breeding

 Abstract

Cr (III), Mn(III),Fe(III)and M(III) complexes with a Schiff base derived from 2-amino-4-ethyl-5-hydroxybenzaldehyde and thiocarbohydrazide were synthesised and characterised using a variety of techniques, including elemental analysis (C, H,N), molar conductance measurements, magnetic measurements, and electronic, mass, and IR spectral studies. A five-coordinated square pyramidal geometry was suggested for all the complexes based on these findings. The Schiff base ligand and the complexes were also evaluated for antibacterial activity (against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus megaterium, and the fungus Kluyveromyces fragilis, Rhodotorula rubra, Candida albicans, and Trichoderma reesei). Additionally, an attempt was made to correlate the complexes' antimicrobial activity with their geometry. Each complex was shown to be less active against E. coli, S. aureus, and P. aeruginosa. Although the Cr (III) complex had the greatest antibacterial action, the ligand alone was shown to be potent against the fungus T. reesei.
