Knowledge of comparative effectiveness of different selection methods is necessary for identification of superior genotypes, efficient management of populations, and use of available resources. Mass, F2-derived-family, and single-seed-descent (SSD) selection methods were compared in an interracial population (ICA Pijao × Pinto UI 114) of common bean (Phaseolus vulgaris L.). The F2-derived-family method involved elimination of low-yielding F2-derived families in replicated yield trials in F4, F5 and F6. Thirty-two random lines derived from each method and the two parents were evaluated in a replicates-in-set design in two contrasting environments in Colombia in 1992. Mean seed yield of lines derived from the SSD method was significantly lower than yields obtained from the other two methods. Mean yield of lines derived from the pedigree method was the highest, indicating that even a low intensity of selection for yield among F2-derived families was effective. The F2-derived-family method also retained a comparatively higher proportion of lines with lighter-colored medium-sized seeds and indeterminate prostrate type III growth habit. Lines with darker and smaller seeds predominated in the mass and SSD methods. These two groups also had more erect type II lines than did the F2-derived family method. On average, the SSD gave early maturing and the mass method late maturing lines. No line from any method outyielded ICA Pijao, the high-yielding parent. Two lines from the F2-derived-family method, four lines from the mass method, and no lines from the SSD method significantly outyielded Pinto UI 114.

Common bean (Phaseolus vulgaris L.) is a relatively new crop in western Canada. Considerable effort is currently underway in Saskatchewan to expand bean production under both irrigated and rainfed conditions. The objectives of this study were to evaluate the performance of pinto bean genotypes under irrigation in the field and to determine the presence of phenological plasticity among specific pinto bean genotypes when subjected to intermittent drought stress. Six bean genotypes, three determinate and three indeterminate, were grown under irrigated conditions in the field in Saskatoon, SK, in 1994 and 1995. The same genotypes were grown under well-watered and drought stress conditions in the growth room. In the field, indeterminate genotypes were superior in seed yield. The indeterminate genotypes were also superior in seed yield in the growth room under well-watered conditions. Two indeterminate genotypes and one late-maturing determinate genotype performed well when drought stress was intermittent, but yielded the same or less than the early-maturing determinate types when drought stress was severe. The indeterminate genotypes and one late-maturing determinate genotype showed stronger recuperative growth than early-maturing determinate genotypes when released from drought stress. Recuperative growth resulted in delayed maturity relative to growth under optimum soil moisture levels, but it had little effect on other characteristics.

Recently, interracial hybridization was used successfully in breeding common bean (Phaseolus vulgaris L.), but its use has not been adequately documented. Approximately 125 lines with medium-sized seed were selected in the first cycle, mostly from race Durango × race Mesoamerica (both from the Middle American domestication center) single- and multiple-cross populations, for disease resistance and race Durango characteristics. Fifteen of these improved lines, three race Durango control cultivars, and one control cultivar each from races Jalisco and Mesoamerica were evaluated for 3 yr (1989–1991) at three locations in Colombia. A randomized complete block design with three replications was used. Lines were developed using visual mass selection for seed yield and/or resistance to diseases in F2 and F3, followed by single plant harvests in F4 or F5 and seed increases in F6 or F7. Lines resistant to bean common mosaic virus and possessing other desirable traits were yield-tested in F7 or F8. All but two lines outyielded Alteño and Flor de Mayo, the highest yielding control cultivars from races Durango and Jalisco, respectively. Two lines also outyielded Carioca, the race Mesoamerica control cultivar. Improved lines tended to possess higher yield per day. All lines were resistant to bean common mosaic virus and most lines also carried a high level of resistance to anthracnose. Plant, seed, and maturity characteristics of most improved lines were similar to those of race Durango control cultivars. These results support the use of interracial hybridization in improving race Durango common bean.

SUMMARYTo develop an effective breeding programme for rainfed production of the common bean (Phaseolus vulgaris L.), the inheritance of seed yield under such conditions should be understood, preferably considering the effects of environment to account for site or season specificity. Thus, heritability, expected and realized gain from selection, and combining ability were evaluated for a nine-parent diallel of common bean without reciprocals but including parents, at two locations each in Mexico and Colombia, using the F2 and F3 population bulks. Heritability estimated from regressions of F3 on F2 ranged from 0·09 ± 0·18 (S.E.) to 0·75±0·25 for seed yield, from 0·26±009 to 0·34±009 for days to maturity and from0·57±004 to 0·80±004 for 100-seed weight. Expected gain from selection in the F2 was estimated as a percentage of the population mean, selecting the upper 20% of the populations. Expected gain in seed yield ranged from 1·8 to 8·4% in Mexico and from 6·5 to 28·1% in Colombia. Realized gains in seed yield in the F3 were 0·4–7·4% in Mexico and 2·9–15·7% in Colombia. Realized gain values for days to maturity were < 2·2%, and for 100-seed weight > 13·4%. General combining ability (GCA) mean squares (estimated using Griffing's Method 2, Model 1) were significant (P <0·01) and larger than those for specific combining ability (SCA) for all traits at all locations. The parents from the Mexican highlands tended to have a positive GCA effect for yield in Mexico but negative values in Colombia, whereas parents adapted to mid-elevation tropical environments showed the opposite tendency. However, all significant GCA values of breeding line V8025 were positive in both countries.

Twenty experimental lines of small-seeded common bean (Phaseolus vulgaris L.) of Middle American origin from the second cycle of selection (SCS) in multiple-cross intra- and interracial populations were evaluated with two control cultivars from the first cycle of selection (FCS) derived from single-cross intraracial populations and three standard controls at three locations for 3 yr (1988–1990) in Colombia. A 5 × 5 lattice design with four replications was used. Each plot consisted of four rows, 5 m long in the first year and 7 m long in the next 2 years. To develop experimental lines in both selection cycles, visual mass selection for seed yield and/or resistance to diseases in individual plants and plant-to-progeny rows was practiced in early generations. The F2 and F3 were managed by the single-pod bulk method followed by the single plant harvests (F4 or F5), progeny tests (F5 or F6), and seed increases (F6 or F7). The F4- or F5-derived lines were tested for seed yield in F7 or F8. Thirteen lines from the SCS outyielded both control cultivars from the FCS and one standard control. However, only two lines, A 785 and A 774, from the SCS outyielded the best standard control, cultivar Carioca, by an average of 7.7%. Both lines were derived from interracial populations involving high-yielding parents possessing positive general combining ability for seed yield. Most improved lines from the SCS possessed higher yield per day and higher disease resistance. No apparent changes were recorded in days to maturity and 100-seed weight for high-yielding lines. Late-maturing lines usually had lower yield and yield per day.Key words: Phaseolus vulgaris, small-seeded common bean, seed yield, cycles of selection, intra- and interracial crosses

Plant Injury

Metobromuron is a major preemergence herbicide controlling mainly broadleaf weeds in common bean production in Ontario. Rainstorms at the seedling stage may splash metobromuron on the plants which results in serious injury, reduced plant stand, and low seed yield. This study determined the appropriate rates of metobromuron for identification of germplasm tolerant to the herbicide. Metobromuron of 0, 0.28, and 0.56 kg ai ha−1 in the glasshouse and 0, 0.28, 0.42, and 0.56 kg ha−1 in the field were applied POST at the unifoliolate stage of 30 bean cultivars. A significant linear effect of herbicide rate on plant injury and recovery was detected. Plant growth was reduced significantly on sensitive cultivars. Two cultivars, Taylor Hort’ and ‘UI 51’, and several plant introductions were tolerant to metobromuron. A rate range of 0.42 to 0.56 kg ha−1 of metobromuron would be appropriate to separate tolerant from sensitive bean lines.
