· PRESENT'ATI()NS 45both sites. Correlation coefficients for all studied characteristics in the nursery andin the field were calculated. The most important results are related to the preplantingheight, which revealed a significant correlation with lOO-seed weight(r=O.5Sl**), seed length (r=0.463**) and seed width (r=0.4S4**). The nurserygermination capacity did not show any significant correlation with other traits. Theresults from this analysis are shown for nursery germination and lOO-seed weightin Figure 2.100 F62&.
