| genetic diversity of fusarium oxysporum strains from common bean fields in spain. | fusarium wilt is an endemic disease in el barco de avila (castilla y león, west-central spain), where high-quality common bean cultivars have been cultured for the last century. we used intergenic spacer (igs) region polymorphism of ribosomal dna, electrophoretic karyotype patterns, and vegetative compatibility and pathogenicity analyses to assess the genetic diversity within fusarium oxysporum isolates recovered from common bean plants growing in fields around el barco de avila. ninety-six vege ... | 1999 | 10427016 |
