Abstract

A periodic comparison of cultivars is essential
to assess selection gains, determine deficiencies,
define objectives, and set breeding priorities.
Our objective was to assess the progress,
or lack thereof, achieved in improving yield,
plant type, maturity, and resistance to major
bacterial, fungal, and viral diseases of dry bean
of the western USA from 1918 to 1998. Twenty-five
great northern, pink, pinto, and red cultivars
were evaluated for seed yield at three locations
in Idaho and for anthracnose, Bean common
mosaic virus, Bean common mosaic necrosis
virus, common and halo bacterial blights, Fusarium
and Rhizoctonia root rots, Fusarium wilt, and
white mold in Colorado, Idaho, and Washington
between 1999 and 2006. Yield ranged between
2904 kg ha-1 for pinto 'UI 111' to 3921 kg ha- 1
for 'Bill Z', which represents a 35% gain in 54
yr. Yield gain in great northern was 587 kg ha-1 ,
pink 136 kg ha-1 , and red 687 kg ha- 1 . Stability
indices ranged from 0.57 for 'Kodiak' to 1.86 for
'UI 3'. Maturity ranged from 90 d for 'UI 320' to
97 d for 'Frontier'. Seed weight ranged from 28
g for 'Viva' to 41 g for UI 320. An acceptable
degree of resistance to Rhizoctonia root rot was
achieved in most cultivars. All cultivars were
susceptible to anthracnose, common bacterial
blight, and white mold, and all except 'Chase'
to halo blight. Only 'Matterhorn', 'Weihing', and
Kodiak combined an upright Type II growth
habit with resistance to BCMV and rust. An integrated
breeding strategy should be explored for
simultaneous improvement of multiple traits in
future cultivars.
