Variability is one of the most common research problem for students of Genetics and Plant breeding. The video deals with three aspects of Variability analysis in R 1) Genetic parameters: Genotypic and Phenotypic Variance, Heritability, Genetic Advance and Genetic Advance as percentage of Mean 2) Genotypic and Phenotypic Correlation 3) Path analysis Time Stamps: 0:00 Introduction 1:24 Description of dataset and import in R 3:34 Installation of variability package 4:48 Calculation of Genetic parameters like Heritability, GA, GA as % of mean 11:20 Genotypic and Phenotypic correlation 16:21 ANCOVA and calculation of Genotypic & Phenotypic Covariance 17:30 Path Analysis Link for blog Part I: Genetic parameters https://medium.com/@popatrajc/variability-analysis-in-r-i-genetic-parameters-26f9ee90e741 Part II: Genotypic & Phenotypic correlation https://agriculturalstatistic.blogspot.com/2020/12/varibility-analysis-in-r-ii-genotypic.html Part III: Path Analysis https://agriculturalstatistic.blogspot.com/2020/12/varibility-analysis-in-r-iii-genotypic.html Dataset link https://drive.google.com/file/d/1sda2kBdpwNes6l1pXqPlls96gX9euqtX/view?usp=sharing Link for formulas https://drive.google.com/file/d/1SCynvFUGqP0Hjq5ZkXv5zbv-UXo1vTif/view?usp=sharing If you are using the variability R package in research work you can cite it as: Raj Popat, Rumit Patel and Dinesh Parmar (2020). variability: Genetic Variability Analysis for Plant Breeding Research.
