Sample note
The material (Accession Number 592391) were obtained from USDA National Plant Germplasm system. The seeds were planted and cultivated in a greenhouse at 18-25 °C located at the National Institute of Agricultural Sciences, Jeonju, Korea. The collecting (by hand) of of florets of early stage samples started approximately 12 weeks after seed planting. These EARLY STAGE flower samples were collected before the beginning of the flowering, when the upper portion of the florets were about to emerge through the bracts. The samples wer snap-frozen using liquid nitrogen, the freeze--dried and stored at -80 ° until further processing. Visually seen, there was not yet much color in flowers, only white and light yellow hues. The length of spine was very short. The leaf shape was lanceolate.
