Estimation of Heritability, Genes Number and Multivariate Analysis Using Non- segregation and Segregation Generations in Two Cotton Crosses

E. F. El-Hashash & W. M. B. Yehia · Asian Journal of Biochemistry, Genetics and Molecular Biology · 2021

This study was conducted to evaluate the heritability methods, the genes number equations and comparison between them, as well as multivariate analysis of cotton yield and its components traits in the two crosses G.85 x TNB and G.86 x Suvin. Broad sense heritability (BSH) using M...

Methods for Determining the Tetrachoric Correlation Coefficient for Binary Variables

E. F. El-Hashash & K. M. El-Absy · Asian Journal of Probability and Statistics · 2018

The tetrachoric correlation coefficient (rt) is a special case of the statistical covariation between two variables measured on a dichotomous scale, but assuming an underlying bivariate normal distribution. Our goal was to provide an analysis of seven different methods used to ca...

Genetic Parameters, Multivariate Analysis and Tolerance Indices of Rice Genotypes under Normal and Drought Stress Environments

E. F. El-Hashash, R. Y. A. EL-Agoury, K. M. El-Absy & S. M. I. Sakr · Asian Journal of Research in Crop Science · 2018

In order to evaluate genetic parameters and drought tolerance indices using multivariate analysis, seventeen genotypes of rice were evaluated under normal and drought conditions. The combined analysis of variance indicated highly significant effects of genotype on all studied tra...
