Title:
 The comparison of hand-made and computerized measurements in DUS trials on oil-seed rape

Language: English

Keywords:

oil-seed rape

Summary:
In a paper two methods of making measurements of some characteristics in distinctness, uniformity and stability (DUS) trials are compared. The results of parallel measurements concerning cotyledon length and width and petal length and width for 30 oil-seed rape varieties are used. Measurements were performed both by traditional method (using electronic caliper) and by special program (using scans of measured objects). Variety mean values (used in testing distinctness) and variety standard deviations (used in testing uniformity) were often significantly dependent on the method of making measurements.
