Varieties used for comparison: 'La Paz' and 'Pintoba'
Summary: 'Mariah' has an indeterminate bush habit with erect stem and branches with guides and the ability to climb whereas 'Pintoba' has an indeterminate bush habit with weak and prostrate stem and branches with long guides with the ability to climb. The hilar ring of 'Mariah' is yellow whereas it is self-coloured on 'Pintoba'. 'Mariah' has 'I' resistance to bean common mosaic virus, NL3 strain whereas 'La Paz' and 'Pintoba' are susceptible. 'Mariah' matures earlier than both reference varieties.
PLANT: anthocyanin colouration of hypocotyl absent, indeterminate bush habit with erect stem and branches with guides and ability to climb, climbing starts mid-season
LEAF: medium green, medium rugosity
FLOWER: medium sized bracts, white standard and wings
POD: red pigmentation, sparse flecks, slight to medium curvature towards ventral part, medium length beak
SEED: ovate shape of median longitudinal section, multi-coloured, main colour buff with more than one secondary colour, weak veins, yellow hilar ring
SECONDARY COLOUR: mainly brown, speckled pattern, randomly scattered
DISEASE REACTION: Resistant to Bean common mosaic virus (BCMV), NY15 strain and 'I' resistance to NL3 strain present, resistant to rust (Uromyces appendiculatus) race 53
Origin & Breeding History: 'Mariah' was developed by pedigree selection from the cross 'H9657-42-2', as the seed parent, and 'Buster', the pollen parent, made in January, 2000 at the Seminis Western Breeding Station in Filer, Idaho, USA. The F1 was planted out in the field that year and allowed to multiply. Early selections were made during the F2 for upright productive structure and desirable seed appearance. Bulking of successive generations along with additional selection for resistance to weathering when exposed to light and moisture, maturity, uniform ripening and yield potential were carried out. 'Mariah' was tested as 'EX08540800'.
Tests & Trials: The tests and trials for 'Mariah' were conducted at Parent Seeds, St. Joseph, Manitoba during the summers of 2007 and 2008. Trials consisted of 2 replicates per variety, consisting of 2 rows per replicate, measuring approximately 6.5 metres in length, with a row spacing of approximately 1 metre. Plants were spaced about 5 cm apart in the rows. Maturity data were extracted from the 2006 and 2007 Manitoba Dry Bean Cooperative Registration Trials.
