Theoretical Improvement of Autotetraploid Crops: Interpopulation and Intrapopulation Selection

摘要

This paper presents equations for expected genetic progress for interpopulation and intrapopulation breeding schemes for autotetraploid corps. Equations are developed for the change in the genotypic means of a single population, a hybrid of two populations, and a synthetic variety of two populations with a single cycle of selection as a function of population parameters and change in allele frequency. Also, response equations are developed for changes in allele frequency and genotypic population menas with intrapopulation breeding schemes, and more difficult response equations are developed for changes in genotypic mean of a hybrid population or synthetic variety as a function of breeding method.
