| CHEMICAL | Oil Percentage | Whole kernel oil concentration corrected to a standard moisture level (dry weight basis). Value is expressed in percent oil. The method of obtaining the value is described in the method record and may be by calibrated NIR or using wet lab procedures. | 4.6 | | MAIZE.NIR.DUPONT-PIONEER.2000 | PI 550520 99ncai01 SD | |
| COMMENT | Notes and Remarks | Observations made by cooperators or curators while evaluating or regenerating germplasm. Usually these observations are not published and need verification or there are too few observations of this type to promote a separate trait. | OBSERVATION-NURSERY_YES | | MAIZE.OBS.INBRED.DIVERSITY.2010.NCIANYMO | PI 550520 99ncai01 SD | |
| DISEASE | Stewarts Wilt | Plant response to the Stewart's wilt organism (Pantoea stewartii subsp. stewartii (Smith) Mergaert, Verdonck & Kersters) formerly called (Erwinia stewartii (Smith) Dye ).
