After reading this article you will learn about the gene and its role in population. Genetically defined, a genetic population is a spatial-temporal group of conspecific interbreeding individuals. All genetic information distributed among an interbreeding group of individuals collectively form a gene pool. The gene pool concept is best represented by small isolated colonies whose members can interbreed in a [...]
Justifications for the development and use of MAS in plant breeding fall into four broad areas that are relevant to almost all target crops. These are: a. Traits that are difficult to manage through conventional phenotypic selection because they are expensive or time consuming to measure, or have low penetrance or complex inheritance. b. Traits whose selection depends on specific [...]
After reading this article we will learn about the estimation of additive and dominance variance. Additive (D) and dominance (H) genetic variances are easily computed with the help of following formulae. In some nomenclatures additive variance is denoted by A and dominance by H. where, V = Variance, ½ D = additive genetic variance, 1/4H = dominance variance, and VE [...]
