Mejoramiento genético para tolerancia a altas temperaturas y resistencia a mosaico dorado en frijol común.

In 1994-95, sources of heat tolerance were identified in common beans after screened several germplasm and advanced lines nurseries in Choluteca and Nacaome (≤ 50 masl), in the southern region of Honduras. The best heat tolerant genotypes were validated under greenhouse controlled conditions (35/27 °C day/night) in Geneva, New York. Afterward, crosses were made to develop small-red bean lines with heat tolerance and resistance to BGMV and other limiting factors. The F2- F5 segregant populations were evaluated for multiple traits including BGMV, common bacterial blight, angular leaf spot, rust, low fertility conditions, and selected for agronomic performance and commercial value. In 1998, 217 F6 and F7 advanced lines were evaluated in the irrigation district Lempa-Acahuapa (20 masl), in the Pacific region of El Salvador for heat tolerance and BGMV. The same nurseries were evaluated in Liberia, in the Northwest region of Costa Rica, for tolerance to high temperatures; and at Zamorano, Honduras for resistance to common bacterial blight, angular leaf spot and rust. A group of lines were identified having superior yield and adaptation than commercial checks, under high temperature conditions in El Salvador and Costa Rica. Some of these lines were also resistant to BGMV in El Salvador, and moderate resistant to web blight in Costa Rica, and they had excellent agronomic performance and good commercial value.

Resistance Patterns

Diseases and insect pests are major causes of low yields of common bean (Phaseolus vulgaris L.) in Latin America and Africa. Anthracnose, angular leaf spot and common bacterial blight are widespread foliar diseases of common bean that also infect pods and seeds. One thousand and eighty-two accessions from a common bean core collection from the primary centres of origin were investigated for reaction to these three diseases. Angular leaf spot and common bacterial blight were evaluated in the field at Santander de Quilichao, Colombia, and anthracnose was evaluated in a screenhouse in Popay�n, Colombia. By using the 15-group level from a hierarchical clustering procedure, it was found that 7 groups were formed with mainly Andean common bean accessions (Andean gene pool), 7 groups with mainly Middle American accessions (Middle American gene pool), while 1�group contained mixed accessions. Consistent with the theory of co-evolution, it was generally observed that accessions from the Andean gene pool were resistant to Middle American pathogen isolates causing anthracnoxe, while the Middle American accessions were resistant to pathogen isolates from the Andes. Different combinations of resistance patterns were found, and breeders can use this information to select a specific group of accessions on the basis of their need.

Foliar Diseases

Seventeen dry bean genotypes were tested in 18 field trials on small farms and experiment stations in the Dominican Republic in the 1981-1982 growing season, and 20 bean genotypes were tested in 10 trials in the 1982-1983 growing season to measure the reaction of promising dry bean genotypes and standard cultivars from the Dominican Republic to natural infection of foliar diseases, and to determine the frequency and intensity of foliar diseases when dry beans are generally grown in the Dominican Republic. Bacterial blight [Xanthomonas campestris pr. phaseoli (Smith) Dye] was the most serious disease during the September plantings. Rust [Uromyces phaseoli (Reben) Wint.] was the most prevalent disease when beans were planted in January, which is a drier month. There was little difference among the dry bean genotypes in reaction to bacterial blight. All of the genotypes developed at least a moderate level of infection of bacterial blight following the September plantings. However, several genotypes expressed high levels of resistance to rust. Among the standard red mottled cultivars, Pompadour developed the lowest level of rust infection. Angular leaf spot (lsariopsis griseola Sacc.) and chaetoseptoria leaf spot (Chaetoseptoria wellmanii Stevenson) also were observed in several experiments. One genotype, 5B-42-2-1, expressed a low level of infection to angular leaf spot having an average score of 1.5, whereas all genotypes were found to be susceptible to chaetoseptoria leaf spot.

Angular leaf spot (ALS) caused by Pseudocercospora griseola is among the devastating diseases of common bean (Phaseolus vulgaris L.) in the Southern Highlands of Tanzania (SHT). This study was conducted to assess the agronomic performance and economics of yield loss associated with the disease on five bean cultivars that are widely grown by farmers. The cultivars were evaluated in a split plot design with a randomized complete block arrangement during 2012/2013 and 2013/2014. The main plots were two rates of fungicide and a control whereas the subplots consisted of cultivars. Data were collected on disease severity, yield, and yield components. Analysis of variance was done and marginal rate of returns determined using partial budget. Results indicated significant decrease in yields, number of pods, seeds, and seed weight at P < 0.05 for untreated plots. Decreases in yield were associated with ALS disease severity that in turn was influenced by cultivar and rate of fungicide used. Higher grain yield losses of as much as 61% and the lowest marginal rate of returns were recorded for unsprayed plots during heavy rains. Fungicide usage at the recommended rates should be considered during heavy rains and breeding for resistance should be taken as an economical and sustainable strategy for managing the disease.

Natural Incidence

The objective of this study was to select sources of resistance to angular leaf spot and anthracnose from a diverse group of germplasm with known resistance to these diseases and other abiotic and biotic factors. Atotal of 173 common beans that included 46 landraces and 127 breeding lines were evaluated at two locations (Estación Experimental Fabio Baudrit Moreno and Sub-Estación Experimental Fraijanes, both of Universidad de Costa Rica) in 1996 and 1997. A mixture of four races (races 9, 10, 547, and 1024 of maximum virulence and coverage in Costa Rica) of the anthracnose pathogen was used to inoculate four times. Because of high natural incidence of angular leaf spot, inoculation was not necessary. Twenty-one landraces and 13 breeding lines were resistant (disease score of 3 or less) to antracnose. Only five landraces (G 12529, G 14934, G 19428, G 19696, and G 19831), one improved cultivar (ICA Tundama), and a breeding line UCR 55 had intermediate reaction (disease score between 4 and 6). Thus, for angular leaf spot evaluation of a much broader range of germplasm of common bean and other related species is suggested.
