“…The higher yield potential for pink and relatively recently bred red cultivars such as NW 63 (Burke, 1982b) and UI 239 (Myers et al, 1997) was also reported by Muñoz‐Perea et al (2006) in Idaho and has been a common observation in yield trials conducted elsewhere in the western USA. It is noteworthy that pink bean is prominent in the pedigree of Bill Z (Wood et al, 1989) and UI 239, the highest‐yielding cultivars, respectively, for the pinto and red market classes. Among pinto cultivars, Bill Z had the highest and UI 111, released in 1944, the lowest yield.…”

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. Twentyfive great northern, pink, pinto, and red cultivars were evaluated for seed yield at three locations in Idaho and for anthracnose,

“…Nonetheless, Common Red Mexican was used extensively as a source of adaptation to semiarid environments and resistance to Beet curly top virus (a leafhopper‐vectored geminivirus) in dry bean breeding programs in the western USA. For example, cultivars Othello (Burke, 1982), Bill Z (Wood et al, 1989), UI 239 (Myers et al, 1997), UI 259 (Myers et al, 2001b), and NW 63 (Burke et al, 1995) have Common Red Mexican in their parentage (Miklas, 2000).…”

Selection for Drought Resistance in Dry Bean Landraces and Cultivars

Drought is a worldwide constraint to dry bean (Phaseolus vulgaris L.) production. The objective of this research was to determine the response of three dry bean landraces and 13 cultivars evaluated under non-stressed (NS) and intermittent drought-stressed (DS) environments at Kimberly, Idaho in 2003 and 2004. The NS received seven irrigations in 2003 and five in 2004, and DS only four in 2003 and two in 2004. Most water use occurred within the top 0.5 m soil in both the NS and DS. Drought reduced biomass and seed yield, harvest index, and seed weight. Maturity was delayed in severe drought, but was similar or shortened by 1 to 6 d under moderate drought. Mean seed yield was reduced by 62% in 2003 and by 27% in 2004. Common Red Mexican and CO 46348 had high seed yield in both NS and DS environments, whereas 'Matterhorn' and 'Othello' yielded comparatively high under DS but moderately in NS environment. Drought resistance was inadvertently reduced from Common Red Mexican landrace to intermediate levels in 'NW-63' and 'UI 239' released in 1979 and 1993, respectively, and more recently released 'LeBaron ' (1999) and 'UI 259' (1996) were susceptible. Conversely, drought resistance was increased in newer pinto (Othello 1986; CO 46348) and great northern (Matterhorn 1998) releases compared to the landraces and older cultivars tested for those market classes. Seed yield in NS and DS was positively correlated. Seed yield was also correlated with harvest index in DS and NS. All early maturing cultivars except Othello (e.g., UI 59, US 1140, Common Pinto, Topaz, UI 320, and LeBaron) were susceptible. Common Red Mexican did not have any reduction in seed weight due to drought stress. Drought resistant genotypes should be used for determining irrigation frequency, amount of water to be applied, and mechanisms of resistance and for identifying, mapping, and pyramiding favorable genes for dryland and irrigation-assisted sustainable production systems.

“…We further evaluated these tropical genotypes (SEC 10, SEN 3, SEN 20, SEN 21, SER 10, SER 22, and SER 26) (Table 1) in the current study with two great northern cultivars (Matterhorn [Kelly et al, 1999] and Beryl-R) and one pinto cultivar (Bill-Z) (Wood et al, 1989) serving as checks. Many of these genotypes were derived from crosses between Durango and Mesoamerican gene pools (S. Beebe, personal communication, 2005).…”

Selection for Drought Tolerance in Dry Bean Derived from the Mesoamerican Gene Pool in Western Nebraska

Dry bean (Phaseolus vulgaris L.) is highly susceptible to drought stress, and drought affects 60% of global bean production. We evaluated elite exotic dry bean germplasm derived from the Mesoamerican gene pool for drought tolerance, yield, and adaptation to western Nebraska during 2006 and 2007 at three research sites. Seven tropical lines were evaluated with two great northern cultivars (Matterhorn and Beryl‐R) and one pinto cultivar (Bill‐Z) serving as checks. Adjacent nonstressed (NS) and drought‐stressed (DS) blocks were evaluated. Within each block, the selected lines were assigned to experimental units using a randomized complete block design with four replications at each location. On average, yield was 60% less, 100‐seed weight was 19.2% lower, and maturity occurred 4 d earlier under DS than under NS conditions. Beryl‐R, SER 22, and Matterhorn had the greatest average yield under both NS (3564, 3347, and 3440 kg ha−1, respectively) and DS (1701, 1773, and 1584 kg ha−1, respectively). These genotypes were also the most drought tolerant based on the drought susceptibility index (0.9, 0.8, and 0.9, respectively) and geometric mean (2462, 2436, and 2335, respectively). Based on these results, Matterhorn, Beryl‐R, and SER 22 show the most promise for use in breeding for drought tolerance.
