Variety Description

Variety used for comparison: 'Eclipse'

Summary: 'Sorento' has a slightly taller plant height than 'Eclipse'. At flowering, 'Sorento' has a green plant colour while it is yellow green in 'Eclipse'. The density of stipule flecking in 'Sorento' is sparser than in 'Eclipse'. 'Sorento' has a slightly stronger curvature of the pod than 'Eclipse'. 'Sorento' has a cream to white flower colour while it is white in 'Eclipse'.


PLANT: field type, no stem fasciation, green colour at flowering, no anthocyanin colouration, semi-leafless
STEM: medium length vine, no anthocyanin in axils
STIPULE: strong waxiness of upper surface, moderate dentation, normal development, no rabbit-eared stipules, no anthocyanin colouration, sparse flecking

FLOWER: mid to slightly later bloom, medium number of flower bearing nodes per stem, two flowers per node, cream to white standard, base of standard is level, acuminate apex of upper calyx lobe, medium length peduncle

POD: parchment partially present, weak concave curvature, distal part predominantly blunt, yellowish green when fully swollen, no strings of suture, no anthocyanin colouration, 6 to 8 ovules
IMMATURE SEED: light to medium green
DRY SEED: simple starch grain, yellow cotyledon, no marbling, no spots on testa, no black hilum, spherical shape, weak to moderate dimpling, medium size, mid-season to slightly later maturity

Origin & Breeding History: 'Sorento' (experimental designations Ceb 4163, 98075-135) is the result of the cross 97122 x 97147 made during 1998 in Lelystad, The Netherlands, where 97122 = 91043-516 x Agadir; 97147 = Eclipse x Agadir; 91403-516 is Ceb 1136 x Baccara; and Ceb 1136 = Solara x {(Flavanda x Progreta) x Flavanda}. A single plant was selected by pedigree selection method, followed by single seed descent to the F4 generation. The F4 generation was screened for resistance to powdery mildew in 2001. Yield trials were conducted during the F5-F7 generations in years 2002-2004. The variety was also tested for stiffness and straw strength in the F4 to F7 generations. One line was bulked in the F7 generation to form this variety.

Tests & Trials: Tests and trials for 'Sorento' were conducted in Westlock, Alberta in 2006 and Barrhead, Alberta in 2007. The candidate and reference varieties were seeded in a 4 replicate randomized complete block design. Each plot consisted of 4 rows per variety, spaced at 20 cm. The plots were seeded to 6 metres and trimmed to 4 metres. Measured observations were based on 20 measurements.
