THE USE OF DIALLEL CORRELATIONS FOR DETERMINING THE RELATIVE LOCATIONAL PERFORMANCE OF VARIETIES OF BARLEY

Abstract

Using diallel correlation coefficients based on the yield of nine varieties of barley, eight of the ten test locations in the Upper Peace River region can be arranged into three completely inter-related response groups. Each group has one location in common with the adjoining group. The locational associations for height, bushel weight and 1000-kernel weight are not as consistent but, with a few exceptions, approximate those established for yield. The groupings suggest that the number of barley test locations in the region could be reduced from ten to five without an appreciable loss of information.
