Summary: 'ND-307' has short guides whereas 'Windbreaker' has medium length guides. The intensity of green colour of the leaves of 'ND-307' is medium whereas it is dark on 'Maverick'. 'ND-307' flowers mid-season whereas 'Maverick' flowers early. The hilum ring on 'ND-307' is orange whereas it is yellow on both reference varieties.


PLANT: dwarf growth type, semi-determinate, short guides, flowers mid-season

LEAF: medium green

FLOWER: white standard and wings

POD: elliptic shape in cross section, green ground colour, stringiness of ventral suture absent, secondary colour brown

SEED: pinto type, two colours, main colour beige, orange hilum ring

DISEASE REACTION: Resistance to Bean common mosaic virus (BCMV) is mosaic and blackroot development absent, resistant to rust (Uromyces appendiculatus) races 47 and 53.

Origin & Breeding History: 'ND-307', tested as ND010307, is a selection from the cross USPT-CBB-3 / Matterhorn // Maverick. The final cross took place in the spring of 1999 in a greenhouse in Fargo, North Dakota. The F1 population (99-049) was grown in the field in Fargo, North Dakota in 1999. The F2 population was grown in a nursery near Hatton, North Dakota in 2000. Single plant selections were made in the F2 based on plant architecture, pod load, plant vigour, maturity and lack of foliar diseases. The F2:3 line (99-049-03) was grown in an off-season nursery in Isabela, Puerto Rico during the winter of 2000-2001 and was selected for vigour, productivity, lack of visible foliar pathogens and maturity. The row was harvested in bulk as F2:4 seed and was entered into a pinto preliminary yield test at Erie and Hatton, North Dakota in 2001. Simultaneous evaluation for reaction to Bean Common Mosaic Virus and bean rust were made in a greenhouse in Fargo, North Dakota. Continued evaluation from 2002-2007 in advanced yield trials at multiple sites in North Dakota and other states verified agronomic performance.

Tests & Trials: The tests and trials for 'ND-307' were conducted at Morden, Manitoba during the summers of 2010 and 2011. Trials consisted of 3 replicates per variety, consisting of 4 rows per replicate, measuring approximately 5 metres in length, with a row spacing of approximately 60 cm. Plants were spaced about 5 cm apart in the rows. Height data was extracted from the 2010 and 2011 Manitoba Dry Bean Cooperative Registration Trials.
