Abstract: A spontaneously occurred floralmutant with multi-flower and exhibiting antheroid structure on the top of petals was found in the progeny of a instable self-line of petunia. The anther of the mutant has a resembled structure in normal plants and can p roduce a little infertile pollen in it. The mutants could produce seeds by self-pollinated or pollinated with pollens from the wild type. The similarity and differences of blind-like with similar petunia mutantswas discussed.

Key words: Petunia hybrida, Floral organ, Development, blind-like mutant
