Heritabilities (H) of seed transmission and leaf and pod reactions to common bacterial blight (CBB) Xanthomonas campestris pv. phaseoli (Xcp) and to web blight (WB) Thanatephorus cucumeris (Tc) were studied. The reaction to CBB was quantitatively inherited. H values of .36, .46, and .34 for leaf reaction, .14, .12, and .27 for pod reaction, .53, .26, and .36 for seed transmission were estimated based on variation of F6 lines derived from bean crosses 'PC-50' × XAN-159, 'PC-50'× BAC-6, and 'Venezuela 44' × BAC-6 (greenhouse, NE). No significant correlations were detected between leaf and pod reactions or between pod reaction and seed transmission. Quantitative inheritance patterns were observed for leaf reactions to Xcp, Tc, and architecture (AR) in F6lines from the cross BAC-6 × HT 7719 (field, Dominican Republic). H values of .23 (CBB), .14 (WB), and .30 (AR) were obtained. No significant correlations were detected between CBB with WB or AR. A low correlation (+.22) was found between WB and AR.

The leaf reaction of the Phaseolus vulgaris L. germplasm—UNECA (M6 mutant derived from the cultivar Chimbolito, Costa Rica), `Chimbolito', BAC-6 (Brazil), XAN-159 (Centro Internacional de Agricultura Tropical, Cali, Colombia), and `PC-50' (Domican Republic)—to Xanthomonas campestris pv. phaseoli strain V4S1 (Dominican Republic) were determined in two replicated trials conducted in a greenhouse in Lincoln, Neb. (Feb.–Mar. and July–Aug. 1993). `PC-50' and `Chimbolito' were susceptible to Xcp strain V4S1 in both tests. UNECA, BAC-6, and XAN-159 had similar levels of resistance to Xcp in the July to August trial. However, in the February to March trial, the resistance of UNECA was greater than that of BAC-6 but less than that of XAN-159.

Xanthomonas axonopodis pv. phaseoli (Smith) Vauterin (Xap) and Xanthomonas fuscans subsp. fuscans Schaad et al. (Xff) cause indistinguishable symptoms known as common bacterial blight of bean (Phaseolus vulgaris L.). These results confirm a higher disease incidence and seed transmission frequency of Xff compared to Xap and reinforce the need for seed health tests that can differentiate the two species.

Ten dry bean (Phaseolus vulgaris L.) cultivars/lines with differential reactions to rust were used in growth chamber experiments to determine rust [Uromyces appendiculatus (Pers.) Unger var. appendiculutus, (U a)], and common bacterial blight Xanthomonas campestris pv. phaseoli (E.F. Sm.) Dews. (X c p)] reactions on leaves when coinoculated with both pathogens. The X c p-U a necrosis symptoms were very different from those caused by X c p alone. Depending on the level of host susceptibility to rust, the X c p reaction remained confined within the rust pustule or spread beyond the pustule area, causing a necrosis of the entire leaf. Prior infection of bean seedlings with bean common mosaic virus (BCMV), NY-15 strain, reduced rust pustule size, but did not affect the reaction to X c p. Screening with X c p and BCMV can be done at the same time during the early vegetative stage, but the interactions of U a with X c p and of BCMV with U a need to be considered in screening for resistance.

Field reaction of 25 red mottled bean (Phaseolus vulgaris L.) genotypes to common bacterial blight [Xanthomonas campestris pv. phaseoli (Smith) Dye] was evaluated in Puerto Rico over 2 years. The average disease severity (percent leaf area with symptoms) was similar over years. The determinate red mottled genotypes had almost twice as much disease as indeterminate genotypes. Eight of the indeterminate genotypes had significantly less disease than the mean of the field experiments. These genotypes may serve as useful sources of resistance to common bacterial blight. The size of the chlorotic zone around necrotic lesions varied between growing seasons, showing that environment can influence the expression of common bacterial blight symptoms.

We studied leaf and pod reactions of 18 Phaseolus vulgaris germplasm lines (three temperate and 15 tropical) to four Xanthomonas campestris pv. phaseoli (XCP) (Smith) Dye strains and seven Uromyces appendiculatus (UA) (Pers.) Unger races. Line × XCP interaction was significant for leaf and pod reactions. The common bean lines XAN-159, BAC-6, and XAN-112 had the best combined leaf and pod resistance to XCP. Line × UA race interactions were significant (P = 0.05). Lines IAPAR-14 and BAC-6 had the best combined resistance to XCP and UA.

Meso-american and Andean eommon bean genotypes were inoeulated with mycellium of Thanatephorus cucumeris (Frank), Donk to determine: 1- The interaction among different isolations of Rhizoclonia solani, Kuhn and bean genotypes from two genetic pools, 2- the heritability of resistance to web-blight and 3- the existing genic completion between the meso-american and Andean pools, respeetively. The results found in this experiment were as follows : the strains vary depending of the origin site. Thus, the Dominican Republic and Colombian strains cause a lesser damage to the bean plants. The Panama # 1 isolation is moderately slow, and the Panama # 2 and Costa Rica caused the largest damage to the crop. The RS- 32-Cr strain was the most virulent of all. The heritabiJity shown by crossing was high which indieates that there is genic completion between the meso-ameriean and the Andean pools, respectively. The erossing of of AFR-251 x BAT-1155, in a direct and reciprocal way, showed differences in the F1 and the F2, indicating that the resistance to the disease is controlled by cytoplasmie genes as by nuclear genes. The type of resistance shown by the different evaluated crosses was horizontal and not vertical resistance.

Common bacterial blight, incited by the bacterium Xanthomonas campestris pv. phaseoli (Xcp), is a serious disease of common beans [Phaseolus vulgaris (P. v.)]. Some tepary beans (P. acutifolius) are resistant (R) to Xcp and used to breed P. v. with R to Xcp. The objective was to determine the inheritance of the reaction to different strains of Xcp in crosses between susceptible (S) and R tepary lines. The parents, F2, and F3 populations from six tepary crosses involving 3 R × S, 1 R × moderately (M) R, and 2 R × R were inoculated with Xcp strains EK-11, LB-2, and SC-4A. Different single dominant genes controlled the reaction to different Xcp isolates in R × S crosses. Coupling linkage was detected between the genes controlling the reactions to each of the Xcp strains in the crosses NE #4B(s) × NE #19(R) and NE #4B(S) × CIAT-640005(R), except for NE #8A(MR) × NE #4B(S) with strains EK-11 and LB-2 and EK-11 and SC-4A. Transgressive segregation for S was observed in the F2 and F3 NE #8A × NE #8B(R), indicating that the parents possessed different genes for R. No segregation for reactions occurred n the F2 NE #8B × NE #19 and NE #19 × CIAT-640005, indicating that these parents possessed the same genes for R to the three strains.

Random amplified polymorphic DNA (RAPD) markers were used to construct a partial linkage map in a recombinant inbred population derived from the common bean (Phaseolus vulgaris L.) cross BAC 6 × HT 7719 for studying the genetics of disease resistance in common bean. The linkage map spanned 545 cM and included 75 of 84 markers used in this study. The population of 128 recombinant inbred lines was evaluated for resistance to common bacterial blight, foliar resistance to web blight [WB; Thanatephorus cucumeris (Frank) Donk], and resistance to rust [Uromyces appendiculatus var. appendiculatus (Pers.:Pers) Unger]. Common bacterial blight [CBB; Xanthomonas campestris pv. phaseoli (Smith) Dye] resistance was evaluated for CBB strain Epif-IV in later-developed trifoliolate leaves and for CBB strain EK-11 in seeds, first trifoliolate leaves, later-developed trifoliolate leaves, and pods. In addition, lines were rated for plant uprightness and branch density. Two to six markers accounted for 14% to 34% of the phenotypic variation for each trait. Significant marker locustrait associations were found for 14 mapped loci and 7 of the 9 unmapped markers. The distribution of detected QTL appeared to be nonrandom with most significant markers associated with more than one trait or closely linked to markers significantly associated with variation for a different trait. One marker, BC4091250, was significantly associated with WB resistance, resistance for CBB strain Epif-IV in later-developed trifoliolate leaves, and resistance for CBB strain EK-11 in first trifoliolate leaves, later-developed trifoliolate leaves, and pods. A rust resistance gene was mapped in an interval 14.6 cM from RAPD marker H191050 and 12.5 cM from marker AJ16250.

Total Contribution

Seven hundred and fifty-six random primers were screened with bulks of genomic DNA from common bacterial blight (CBB) resistant and susceptible bean plants. The plants were from a breeding population derived from an interspecific cross between Phaseolus acutifolius and Phaseolus vulgaris. Four RAPD markers, named R7313, RE416, RE49, and R4865, were found to be significantly associated with CBB resistance in this population. Forty-nine molecular markers segregating in the population were clustered into 8 linkage groups by a MAPMAKER linkage analysis. The largest linkage group was 140 cM long and contained 25 marker loci, including marker R4865. Markers R7313, RE416, and RE49 were clustered on another linkage group. A regression analysis indicated that the markers in these two groups together accounted for 81% of the variation in CBB resistance in the population. The addition of another marker, M56810, which was not individually associated with CBB resistance, increased the total contribution to the trait to 87%.Key words: Phaseolus vulgaris L., common bacterial blight (CBB), polymerase chain reaction (PCR), RAPD markers, linkage groups.
