Abstract

A statistical model for statistical analysis has been proposed for biometricians based on testing the n varieties in m environments which lets to explore the general and specific adaptive ability of varieties. The stability characterizes of statistics, are compared across environments for their ability to differentiate the varieties. It was shown that the both general and specific adaptive ability have their variances give more precise information about the stability and differentiative ability of environments. A method for estimation of selection value of a genotype as relative stability (RS) based on the general and specific adaptive ability of varieties is proposed in selection of highly productive and stable ones. Selection for specific adaptive ability taking into stability can be recommended, because the first direction of selection can transform the structure of crop. Predictably given environmental conditions, it is advisable to carry out selection for specific adaptive ability. However, in unpredictable cases, selection of general adaptive ability cause to achieve stability and aid biometricians.
