As a matter of fact, the actors' wish to contribute to a varietal breeding project varies in line with their confidence in genetic progress.
The first five of these can be achieved by substantial changes in research station varietal testing systems in conjunction with laboratory-based tests for food quality.
Thus, in any method for varietal recommendation, one might expect yield to be given a prominent place.
At present, varietal recommendations are based only on yield.
The need for a multivariate approach in varietal recommendation and the proposed method provides an appealing solution to the need.
The value of conducting varietal adaptability trials under properly implemented and varying levels of far mer practice is demonstrated.
The increase in disease may be attributed to warmer weather or the breakdown of varietal resistance.
Numerous authors have proposed analytical methods to remove the effects of such trend from the estimation of varietal contrasts.
