Stability Parameters for Comparing Varieties

  title={Stability Parameters for Comparing Varieties},
  author={Steve A. Eberhart and W. A. Russell},
  journal={Crop Science},
The model, Yij = μ1 + β1Ij + δij, defines stability parameters that may be used to describe the performance of a variety over a series of environments. Yij is the variety mean of the ith variety at the jth environment, µ1 is the ith variety mean over all environments, β1 is the regression coefficient that measures the response of the ith variety to varying environments, δij is the deviation from regression of the ith variety at the jth environment, and Ij is the environmental index. The data…

The characterization of performance of sugar beets by variety × environment interaction

It is demonstrated that the environmental interaction of sugar beet varieties reaches sizable levels and that significant differences exist between the variety-specific interactions.

Genetic properties of four types of stability parameter

It appears that stability parameters of types 1 and 4 are heritable, and thus useful for selection, while those of types 2 and 3 are nonheritable and thus not useful.

Regression methods for studying genotype-environment interactions

This paper considers the two regression methods and their interrelationship from a different point of view and shows that there is a bias in the estimates of the coefficients of regression on the environmental mean when they are derived by the usual method.

Phenotypic Stability of Mixtures – Relations Between the Stability Parameters of a Mixture and Its Components

For each of the two stability parameters (‘regression coefficient’ and ‘sum of squared deviations from the regression’) of the common regression approach (= regression of the yield of population i in

Weighted regression analysis for comparing varietal adaptation

It is revealed that the weighted regression analysis yields more efficient estimates of regression coefficients (bi) than the ordinary regression analysis, and that the standard errors of bivalues were reduced by up to 43%.

The stability of varietal performance over years

Methods of estimating µg are discussed, both when f(e) is known and when only a limited set of effects is available, and it is shown that in the latter case it is necessary to make restrictive assumptions concerning g(e).

The area under the function: an index for selecting desirable genotypes

This study proposes to combine the mean yield and regression coefficient into a unified desirability index (Di), defined as the area under the linear regression function divided by the difference between the two extreme environmental indexes.

A parsimonious statistical design and breeding procedure for evaluating and selecting desirable characteristics over environments

It is shown how to simulate environments that exceed the ranges found in practice and a statistical design is described which is the height of parsimony and has the advantage that the conditions varied are known.

The analysis of variation between and within genotypes and environments

Different techniques are applied to yields of carrots from a trial in which eight varieties were grown in 34 environments representing a set of 17 site/year combinations at two densities, finding the largest source of variation within genotypes is found to be that between environments but not conversely.

Estimates of stability for comparing varieties

The validity of using a single year's across location data with the mean-standard deviation analysis, if choice-theoretic criteria are used, was examined and it is concluded that, although further confirmation is required, single-year data seem to suffice.



The analysis of adaptation in a plant-breeding programme

Varieties from particular geographic regions of the world showed a similarity in type of adaptation, which provides a useful basis for plant introduction and breeding.

Implications of Genotype‐Environmental Interactions in Applied Plant Breeding1

It is found that improvements in efficiency are unlikely so long as only "final" characters such as yield and quality are considered and that real progress will be possible only as the authors clarify the pathways by which final characters are reached.

Intra‐varietal Diversification in Oat Breeding1

General agreement is found on several elements which together may be summed into the one word diversification that the production and distribution of new pure line varieties alone may not be a sufficient measure to provide the desired stability in oat production.
