摘要: The objective of this study was to identify geranium cultivars that exhibit differential reactions floral inoculation with Botrytis cinerea Per. ex. Fr. Sixty-two genotypes, including both and breeding lines, were evaluated from several Pelargonium species. Resistant genotypes included the diploid peltatum (L.) L'Herit. cultivar King Balcon ×hortorum L.H. Bail. Ben Franklin, as well accession 93-1-33 developed an obtained South Africa. Susceptible putative tetraploid Simone. Floral resistance not correlated foliar resistance. Diploid appeared have greater than P. more cultivars. In addition, association petal number investigated.
