Varieties

Long's Peak

A pinto variety released in 2011 from Colorado State University. Long’s Peak combines several desirable commercial pinto bean traits including, excellent seed color and size, high yield potential, resistance to prevalent strains of rust in the High Plains, and resistance to bean common mosaic virus and bean common necrosis virus. Rust resistance is derived from a single recessive gene that allows small rust pustules to form on the leaves late in the growing season. Long’s Peak has upright plant architecture in most environments and has medium plant maturity (94-98 days).

 

 

Shiny Black Pearl

A shiny black-seeded variety released in 2010 from Colorado State University as a proprietary variety to Lee Bean and Seed.  It has an upright Type II growth habit, shiny black seed with medium (95-98 Days) maturity, high seed yield and possesses the I gene for resistance to bean common mosaic virus and bean common necrosis virus.  It was released as a specialty bean specifically for the dry-pack shiny black bean market. Seed coat luster is known to influence water uptake by black beans and water uptake during soaking of shiny seeded black beans is much slower than with traditional opaque luster black bean varieties. Therefore, shiny black beans should not be mixed with opaque seeded black beans or mixed for marketing

Croissant

A pinto variety released in 2008 from Colorado State University.  Croissant combines several desirable commercial pinto bean traits including, excellent seed color and size, high yield potential, resistance to prevalent strains of rust in the High Plains, and resistance to bean common mosaic virus and bean common necrosis virus. Croissant has medium harvest maturity (93 to 98 days) and semi-upright plant architecture in most environments however, in soils with high nitrogen and soil moisture content it can lodge.

 

 

Grand Mesa

A pinto variety released in 2001 from Colorado State University.  Grand Mesa is a medium maturity (94-98 days) variety from Colorado State University.  Grand Mesa combines resistance to rust, bean common mosaic virus, semi-upright Type II plant architecture and field tolerance to white mold, but is susceptible to common bacterial blight and bacterial brown spot.  It has moderate yield potential and good seed quality.

Shiny Crow

A shiny black seeded variety released in 2000 from Colorado State University.  It has a semi-vine Type III growth habit, and resistance to bean common mosaic virus.  It was released as a specialty bean specifically for the dry-pack shiny black bean market.  Seed coat luster is known to influence water uptake by black beans and water uptake during soaking is much slower in shiny seeded black beans than with traditional opaque luster black bean varieties. Therefore, shiny black beans should not be mixed with opaque seeded black beans or mixed for marketing.

Montrose

A pinto variety released in 1999 from Colorado State University. Montrose was released to provide a high yielding pinto variety with improved resistance to rust. It is a medium season variety (94-97 days) with semi-vine type growth habit.  Montrose is resistant to all known races of rust in the Hi Plains and western US.  It has excellent seed quality and possesses resistance to curly top virus, bean common mosaic virus and bean common necrosis virus, and has tolerance to Fusarium root rot.  However, it is highly susceptible to white mold.

Fischer

A pinto variety released in 1995 from Colorado State University.  Fisher was released to provide a high yielding pinto variety adapted to the non-irrigated production systems prevalent in the San Juan Basin region in SW Colorado and NW New Mexico. It is a full season variety (96-99 days) with prostrate semi-vine growth habit.  It carries resistance to bean common mosaic virus and bean common necrosis virus, Fusarium wilt (caused by Fusarium oxysporum fsp. phaseoli) and tolerance to Fusarium root rot.  Fisher is not well adapted to the High Plains and northwestern irrigated regions of the US.

Arapaho

A pinto variety released in 1991 from Colorado State University.  Arapaho was released because it possesses field tolerance to white mold disease caused by Sclerotinia sclerotiorum.  It is a full season variety (95-98 days) with semi-upright growth habit under most growing conditions.  Its upright architecture provides Arapaho with field tolerance to white mold. It is resistant to bean common mosaic virus and bean common necrosis virus, and moderately tolerant to common bacterial blight.  It has good quality.

Bill Z

A pinto variety released in 1985 from Colorado State University.  Bill Z has been one of the most widely grown pinto varieties in the western US and northern highland regions of Mexico.  It combines medium maturity (94-97 days), high yield, excellent seed quality and yield stability into a variety that both growers and processors desire.  It has semi-vine growth habit and carries resistance to curly top, bean common mosaic virus and bean common necrosis virus, with tolerance to Fusarium root rot, common bacterial blight and bacterial brown spot.
