Abstract/Description: | Heritability is one of the most important genetic parameters widely used in plant and animal breeding genetic improvement studies. In literature several methodologies are available for estimation of heritability for different experimental situations. Unfortunately none of these provide always a valid estimate of heritability and the estimate is so inadmissible that no conclusion can be drawn for the inheritance of the trait under consideration. Further in particularly, there is no unique methodology, which is suitable for estimation of heritability in unbalanced situations. Keeping in view this fact, need has been felt that with the help of computer, the sensitivity and robustness of the very widely used genetic parameter, heritability might be studied at length. The sensitivity here refers to that how the estimate of heritability is dependent upon the aberrant or outliers, i.e. whether one or two abnormal data points will really affect the estimate substantially or not. Robustness means that to what extent the estimate of heritability depends upon the underlying statistical distributional assumptions such as that of normality, independence etc. Sandhya Kiran et al. (2004) however studied robust method of estimation of heritability in the case of full sib data |
