Popis:	Common bean germ plasm (Phaseolus vulgaris) with intermediate Ascochyta blight (caused by Phoma exigua var. diversispora) resistance has been identified at CIAT. The heritability and inheritance of resistance to this pathogen were studied in three resistant climbing bean sources. Narrow-sense heritability estimates determined by the regression of the F 2 -derived F 4 line means on F 2 -derived F 3 line means from crosses Carioca (S)×G 10817 (R) and G 10088 (S)×G 10747 (R) were low to moderate (0.19-0.64), depending on the cross and character measured
