Estimation of Genetic Parameters in Plant Breeding: Theory, Example and Demonstration in AgriAnalyze tool

The blog is about estimation of genetic parameters like genotypic variance, phenotypic variance, heritability, genetic advance, genetic advance as a percentage of mean, phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV) for the RCBD trails of genotypes. (Reading time 20 mins). 1.      INTRODUCTION      In a general statistical context, a parameter refers to a numerical characteristic or attribute that describes a population. It can be a fixed value or an unknown quantity that helps to describe or summarize a specific aspect of a population. Genetic Parameter is a statistical measure that quantifies the genetic contributions to traits within a population of an organism. Genetic parameter estimation in plant breeding involves quantifying various genetic components that influence traits of interest, such as yield, disease resistance or quality attributes. These parameters provide critical insights into the genetic basis of these traits, informing bree
