). A stable genotype exhibits high mean performance, a regression coefficient near unity ( ), and a deviation close to zero (

The book delves into quantitative genetics, focusing on polygenic traits—those controlled by many genes—rather than simple Mendelian traits. Key Concepts and Techniques Covered

This model assesses stability using two primary metrics calculated from multi-environment trials: Measures responsiveness to the environment. A value of indicates average responsiveness. Mean Square Deviation from Regression ( S2dicap S squared d sub i ): Measures stability. A value close to

) measures the total genetic contribution to phenotype, while narrow-sense heritability ( hn2h sub n squared
