“…Several studies on resistance to FRR have reported two to four resistance genes. For example, two duplicate recessive genes were reported in crosses between the bean varieties flat marrow and robust pea bean by McRostie (1921); while three recessive genes were reported in PI 165435 and P. coccineus line no. 20145 (Azzam 1958).…”

Fusarium root rot (FRR) is a major disease of common bean worldwide. Knowledge of the inheritance of resistance to FRR would be important in devising strategies to breed resistant varieties. Therefore, a 12 9 12 full diallel mating scheme with reciprocal crosses was performed to generate 132 F 1 progenies, which were then advanced to the F 3 . The progenies were evaluated for resistance to FRR under green house conditions in Uganda. General combining ability (GCA) effects were highly significant (P B 0.01) for disease scores. Specific combining ability effects were not significant (P [ 0.05) in the F 1 , but were highly significant (P \ 0.01) in the F 3 generation. These results indicate that resistance to FRR was governed by genes with additive effects in combination with genes with non-additive effects. Reciprocal differences were also significant (P = 0.01) at F 1 and F 3 , primarily reflecting a large influence of maternal effects in both these generations. In fact, susceptible parents did not differ significantly (P [ 0.05) for disease scores when used as paternal parents in the F 3 , but differed strongly as maternal parents (P = 0.0002). Generally, the progenies were distinctly more resistant when the resistant parent was used as the female in crosses, especially as observed in the F 3 . The maternal effects were strong in the F 3 generation, suggesting a complex form of cytoplasmic-genetic interaction. The non-maternal reciprocal effects in the F 3 were significant (P \ 0.05) in both the resistant 9 resistant diallel, and in the resistant 9 susceptible crosses. Mid-parent heterosis (MPH) occurred in most crosses, with average heterosis approximately equal in each of the three generations, indicating that epistasis was probably more influential than dominance of individual genes. Genenumber formulas indicated that several genes were involved in resistant 9 susceptible crosses. Among resistant 9 resistant crosses, many produced continuous distributions of F 1 progeny scores, suggesting polygenic inheritance, while bi-modal distributions were characteristic of the F 3 distributions, and fit expected ratios for two or three loci segregating in each cross. Dominant forms of epistasis favoring resistance were strongly indicated. Parent-offspring heritability estimates were moderate. Overall, the results indicate that resistant parents contain a number of different resistance genes that can be combined with the expectation of producing strong and durable resistance. The lines MLB-49-89A, MLB-48-89, RWR719 and Vuninkingi, with large and negative GCA effects, contributed high levels of resistance in crosses and would be recommended for use in breeding programs.

“…McRostie (1919) provided evidence that in certain crosses host resistance to each race was governed by a single dominant gene. Resistance to these races was recombined (Burkholder, 1918; McRostie, 1921), but soon a new race, y, developed which overcame the combined resistance obtained in Burkholder's white marrow bean breeding programme (Burkholder, 1923). Burkholder pointed out that race y was pathogenically closely related to , 8 but with increased virulence.…”

SUMMARY Nineteen local isolates of the bean anthracnose pathogen have been obtained and tested over the period 1964–70 for pathogenicity on a set of differential cultivars including the sets of four cultivars each used in the alternative systems of Schreiber and Hubberling and of Bannerot and Blondet. The results indicate the existence of a number of races not conforming to those of either system and the ability, when freshly collected, of some isolates with affinities to both α and β races partially to overcome the immunity of the cultivar Cornell 49–242. The implications of the position as now known from these results and a review of the literature for disease‐resistance breeding are discussed. Tests of the Uganda isolates, on a range of other dry bean cultivars, indicate a tendency for α and δ races to be pathogenic on small‐seeded indeterminate viny or indeterminate bush cultivars, whereas β and γ races tend to be pathogenic on larger‐seeded and determinate cultivars.

A procedure using nutrient culture media was developed to screen bean seedlings on an individual plant basis for reaction to Fusarium solani (Mart.) Appel & Wr. f. sp. phaseoli (Burk.) Snyd. & Hans. From over 800 accessions, 18 plant introductions and several cultivars of Phaseolus vulgaris were found to be either resistant or tolerant. Susceptible plants, grown with ammonium nitrate as the nitrogen source (210 ppm N) showed reduced symptoms compared to plants grown on nitrate-N only. Ammonium as the sole nitrogen source was toxic to bean seedlings at identical nitrogen concentrations. Results based on the nutrient culture technique were generally consistent with field reactions.
