The Population of in Brazil Is Structured by Mycelial Compatibility Groups.

The genetic structure of the population of was analyzed using 238 individuals collected from different hosts. Individuals were characterized for microsatellite genotypes and mycelial compatibility groups (MCGs). A total of 22 MCGs and 64 multilocus lineages (MLLs) were identified.

Inheritance of Anthracnose Resistance in Common Bean Differential Cultivar AB 136.

Inheritance of anthracnose resistance of the common bean (Phaseolus vulgaris L.) differential cultivar AB 136 to races 89, 64, and 73 (binary system designation) was studied in crosses with the susceptible differential cultivars Michelite (race 89), Mexico 222 (race 64), and Cornell 49-242 (race 73). In each cross two progenitors, the F, F, and backcross-derived plants were inoculated with the respective race under environmentally controlled greenhouse conditions.
