Subject(s): Online resources: In: Zagazig Journal of Agricultural Research 2003.v.30(6)Summary: Thirty bean (Phaseolus vulgaris L) genotypes were evaluated for their reactions to infection by Macrophomina phaseolina (Tassi) Goid under greenhouse conditions. Most of tested genotypes were susceptible except Nebraska and Royal Nel that are resistant, while, Morgan, Mexico 309, Sigma, and EMY were intermediate. The studies were based on CrosseS between the resistant genotype Nebraska and the susceptible genotypes (Giza 6 and S1) and the intermediate genotype Morgan. Isoenzymes banding pattern for the four parents ased, in the crosses, Fl ad F2 populations from leaf tissueS showed 20 different peroxidase or esterase anodal bands.
