Qualitative traits, genetic variability and character association for the potential use in breeding programme of mango (Mangifera indica L.)

The concept of heritability is important to determining whether phenotypic differences observed among various individuals are due to genetic changes or due to the effects of environmental factors. Heritability indicates the possibility and extent on which improvement can be brought about through selection. It is a useful measure for considering the ratio of genetic variance to the total variance and is genetically represented in percentage. Correlation measures the degree and direction of relationship between two or more variables. The study of character association helps breeder in fixing a selection criteria for fruit yield in parental lines such as selection will be effective in isolation than correlating the correlation of phenotypic values and subjected to change in the environment. Therefore, Qualitative traits, Genetic Variability and Character Association are essential for better use of varieties/genotypes in crop improvement programme.
