Abstract

In Sortenversuchen sind die Wechselwirkungen Sorten × Orte meist sehr groß und die Mittelwertdifferenzen somit wenig aussagekräftig.

Es wird empfohlen, Landessortenversuche über Landesgrenzen hinweg sekundär regressionsanalytisch auszuwerten, um die Reaktionen von Sorten auf die unterschiedlichen Wachstumsbedingungen der Orte zu erkennen. Auf Aspekte der Auswertung wird näher eingegangen. Die Auswertungsergebnisse der sekundären Auswertung sind für Pflanzenzüchter und Landwirte gleichsam relevant.

In experiments with the aim to characterise varieties, the interaction term variety by location site is often very large and mean differences are not very expressive. With a view to recognising the reaction of the varieties on the specific growth conditions of the local site it is recommended to analyse this so‐called “variety experiments”;, carried out under the auspices of the governments, of the federal states also beyond the borders of the federal states by means of “secondary”; regression analysis.

Methodical aspects are discussed in detail. The “secondary”; results are useful for both plant breeders and farmers.
