The petioles have no anthocyanin colouration and the stipules are small to medium in size. The terminal leaflets are medium ovate in shape with acuminate shaped tips and cordate shaped, strongly asymmetrical bases. The margins of the terminal leaflets have weak waviness. 'Amandine' has five to six pairs of primary leaflets which are medium in size. They are narrowly ovate in shape with acute shaped tips and cordate shaped, strongly asymmetrical bases.

Origin & Breeding History: 'Amandine' originated from a cross between 'Mariana' and 'Charlotte', made in Châteauneuf-du-Faou, France in 1981. Trials were grown in France, Italy, Germany and England from 1983 to 1991. Selection criteria included appearance, yield, resistance to diseases and pests, and culinary quality.
Tests & Trials: Tests and trials for 'Amandine' were conducted at Grand Falls, New Brunswick in 2000. A randomized block design was used with four replicates per variety. All entries were planted in single-row plots which were 5.5 metres long. Spacing between adjacent plots was 91 cm and spacing between adjacent hills within the plot was 30.5 cm. Unless indicated otherwise, measured characteristics were based on 20 measurements.
