The stem wings are conspicuous and straight single. The stem nodes have no swelling and have weak anthocyanin colouration. 'FL 1922' produces many branches.
'FL 1922' has medium green leaves with pubescence on the lower surface. The leaf silhouette is medium. The leaf rachis has weak anthocyanin colouration. There is pubescence on the top and bottom of the leaf rachis. The petiole has medium anthocyanin and the stipules are medium in size. The terminal leaflet is medium ovate in shape with an acuminate shaped tip and truncate base which is asymmetrical. The margin has weak waviness. On average, there are three pairs of primary leaflets which are medium in size. The primary leaflets are medium ovate in shape with an acuminate shaped tip and asymmetrical, truncate base. There are one to four secondary and tertiary leaflets.
'FL 1922' has a high flowering profusion and produces a medium number of florets per inflorescence. The flower bud has no anthocyanin colouration and the buds are persistent. The flowers are blue-violet in colour with strong anthocyanin colouration on the inner side and anthocyanin present on the outer side. The corolla is large in size with a very prominent star. The calyx and peduncle have no anthocyanin. The anthers are orange and arranged in a broad cone shape. The stigma is capitate in shape and dark green in colour. Berry production is low.

Origin & Breeding History: 'FL 1922' originated from a cross made in 1988 between the varieties 'FL 1533' and 'FL 1207'. The cross took place at the Frito-Lay Research facility near Rhinelander, Wisconsin. Seeds from the cross were sown in the greenhouse in the summer of 1988 and the resulting tubers were harvested in the late fall of that year. Seedling tubers were planted in the field in the spring of 1989. One of the selections from this progeny was given the designation RD 84-89-13. This selection was tested for four years in the field near Rhinelander, and found to have excellent chip appearance, with good flavour and resistance to common scab. In 1995 RD-84-89-13 was renamed 'FL 1922'.
Tests & Trials: Tests and trials for 'FL 1922' were conducted at Vauxhall, Alberta in 2003. The trials consisted of 30 metre rows of each variety. The plants within each row were planted 30cm apart, and the spacing between the rows was 90cm. Measured characteristics were based on 50 measurements.
