Objectives  of this project include; verifying the effectiveness of the incorporated ALS, CBB and BCMNV resistance genes against pathogen strains endemic to Tanzania under field and greenhouse conditions; verifying the stability of incorporated (homozygous) genes above using MAS of the advanced backcross lines; conducting yield evaluation on verified lines containing combined ALS, CBB, BCMNV resistance in multi-location replicated trials; conducting on-farm multi-location trials for participatory selection and release of varieties; conducting studies on pathogen variability in major bean growing areas of Tanzania specifically for ALS and Anthracnose.
