“…In total, 25 pinto bean genotypes which included: 16 ND F 4:8 RILs selected from population one (RIL8, RIL9, RIL11, RIL23, RIL24, RIL67, RIL70, RIL78, RIL85, RIL87, RIL90, RIL129, and RIL146) and Population 2 (RIL252, RIL261, and RIL331); four SD genotypes (CDC WM‐2 [Bett et al., 2014], Palomino [Osorno et al., 2018], Staybright [released by Colorado State University, http://www.extsoilcrop.colostate.edu/CropVar/documents/drybeans/beanreport_2017], and P15HR077 [a breeding line from the bean breeding program at University of Guelph]); and five RD genotypes (Burdett [Balasubramanian et al., 2015], P15HR032, P15HR041, and P15HR079 [breeding lines from the bean breeding program at University of Guelph], La Paz, and Windbreaker). All seeds were harvested 8 wk prior to evaluation in 2019 at Elora and stored together until they were analyzed.…”

Investigations of the effects of the non‐darkening seed coat trait coded by the recessive jj alleles on agronomic, sensory, and cooking characteristics in pinto beans

The beige background of the conventional pinto bean (Phaseolus vulgaris L.) seed coat turns brown over time due to oxidation of its proanthocyanidins. Pinto beans that have slow‐darkening (SD) or non‐darkening (ND) seed coats are more desired in the market because they are perceived to be fresh, high‐quality beans. However, correlations between the ND seed coat trait and agronomic performance have not been investigated. Therefore, the objectives of this study were to estimate variance components and broad‐sense heritabilities of agronomic and seed coat traits in pinto beans, and to determine if correlations exist between the ND seed coat trait and agronomic, sensory, and cooking traits in recombinant inbred lines, developed from crosses between ND pinto bean breeding lines, incorporating the ND gene from ‘Wit‐rood boontje’, with two regular‐darkening (RD) pinto bean varieties (‘Stampede’ in Population 1 and ‘La Paz’ in Population 2), grown in four different environments of southwest Ontario in 2016. Analysis of variance indicated significant differences between the RD and ND genotypes for grain yield, 100‐seed weight, hydration capacity, and the seed coat color parameters in both populations. The color parameter L*, which represents the whiteness of the seed coat, was selected as the main discriminative parameter between the RD and ND seed coat phenotypes. There was a weak positive genetic correlation between the ND trait and days to maturity in Population 1 (rg = .11). The ND trait showed weak negative genetic correlations with grain yield (rg = −.23 in Population 1 and rg = −.13 in Population 2). Moderately weak positive genetic correlations were found between the ND trait and hydration capacity in Population 1 (rg = .44) and Population 2 (rg = .40). The ND pinto beans were perceived as sweeter and had softer and smoother textures and shorter cooking times compared with the RD pinto beans.

“…Othello pinto bean (Burke et al 1995) also has a Type 3 growth habit, but is susceptible to white mould. AAC Burdett pinto bean has an indeterminate upright bush (Type 2) growth habit with good lodging resistance at maturity, and therefore, exhibits avoidance to white mould (Balasubramanian et al 2015). Island pinto bean (Mündel et al 2008) also has a Type 2 growth habit with slightly poorer lodging resistance at maturity compared with AAC Burdett, and exhibits avoidance to white mould.…”

Influence of irrigation and plant canopy architecture on white mould disease of dry bean

White mould caused by the fungus Sclerotinia sclerotiorum (Lib.) de Bary is a major constraint to irrigated dry bean production in southern Alberta. Irrigation, coupled with dry bean canopy architecture, may influence white mould by creating conducive environmental conditions. Field experiments were conducted from 2015 to 2017 at Lethbridge to determine the effect of three irrigation levels and five dry bean genotypes with different canopy architectures on white mould. Sensors and data loggers were established to monitor micro-climate data including soil moisture within the top 5 cm, leaf wetness, and soil temperature under the canopy. Canopy porosity, lodging, flower infection, and white mould disease severity were also measured. Higher moisture within the top 5 cm of the soil, lower soil temperature, elevated leaf wetness, and higher white mould incidence were observed in high irrigation plots compared with medium and low irrigation plots. Cultivars varied for leaf wetness, porosity, and lodging. Although a significant interaction between irrigation and cultivar was detected, irrigation levels did not affect disease severity significantly. Lower disease severity and incidence were recorded in AAC Burdett and Island. These cultivars have an upright growth habit, high canopy porosity, and lodging resistance, and therefore, exhibited partial field resistance (avoidance) to white mould. Mean yield across all cultivars was not affected by irrigation; however, the highest yield occurred in the medium irrigation plots. A reduced level of irrigation and development of cultivars with both avoidance and partial physiological resistance may reduce white mould severity and incidence in dry bean fields in Alberta.
