ALLIUM-GARLIC

Data was collected on umbels and bulbols from the Allium sativum and Allium longicuspis accessions grown in the WRPIS clonal Allium nursery planted Oct. 12, 2009 and harvested in 2010. This nursery was grown in the top of field E at the Pullman, WA WRPIS farm. Scapes were left intact on 5 or more random plants per accessions during the growing season. Umbels and bulbols on these 5 plants remained on the scapes with the bulbs at harvest and through cleaning. Bulb harvest ranged from July 21 to Aug. 13. After harvest bulbs were hung in the WRPIS drying shed at room temperature until cleaning. Cleaning times ranged from Sept. 2 to 24. During cleaning the umbels were cut from the scapes and along with loose bulbols placed in labeled paper bags. After cleaning umbels/bulbols were stored at 14C, 40%RH until data collected. Data was collected from Feb. 25, 2011 to May 24, 2011. Unsprouted and turgid bulbols were used for images. If no unsprouted or desiccated bulbols were available the best quality bulbols were used.

For each accession umbels and bulbols were poured into a large plastic tub. The diversity of umbel shape, bulbol size and color was observed. Representatives of the diversity were selected for data collection and images. Data was collected on and images were taken of intact umbels (1-5 depending on the amount of diversity within the accession) and 5 bulbols from each size class of bulbol within the accession. Color designations were made using general color classes (eg pink, purple, brown) and specific colors were recorded using the Munsell Book of Color. A range of Munsell colors were recorded if appropriate.

Quantification of alliin and allicin was performed on an HPLC system that consisted of an HP 1050 pump (Hewlett-Packard, Palo Alto, CA), Shimadzu SIL-9A auto injector (Shimadzu, Kyoto, Japan), Discovery? C18 column (5?m, 25cm x 4.6mm, Supelco, Bellafonte, PA), HP 1050 UV detector and HP 3394 integrator. Sample preparation for analysis of alliin and allicin followed the methods of Iberl et al. (24). Alliin was extracted from 1g garlic powder in 30ml of 50% MeOH (with 0.1% formic acid) by shaking vigorously (250rpm) for 30min at room temperature.

Garlic cloves from NPGS accessions were planted at the National Germplasm Repository for Clonal Vegetables Farm at the Langfang Experimental Station, Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences. Beijing, China in field plots, one accession per plot of 4.5 sq meters with 20 cm between rows and 15 cm between plants, planted in October 2015 and harvested August 2016. The following data was collected from 10 plants per accession right before and after harvest depending on the traits: plant height (cm)(from ground level to natural top of the leaf canopy), plant width (cm) (natural width at widest point in plant canopy), above ground pseudo-stem height (cm) and diameter (mm), number of leaves per plant, leaf length (taken from longest leaf)(cm), leaf width (taken from same leaf used for length)(cm), bulb height (mm), bulb width (mm), bulb weight(g), and number of cloves per bulb.

Note: Leaf width data converted to mm to conform to GRIN-Global descriptor. Bulb Height and Diameter data converted to cm to conform to GRIN-Global descriptor.
