Characteristics of leaflet mutants are shown in Fig 1, while those of the other types are given in Fig 2.
The unifoliate leaf mutant was also sterile, in agreement with that reported by Santos4.
The mutant produced numerous flower buds but failed to open.
The round- cuneat leaflet mutant produced flowers but its pollen scattered all over the corolla and thus expressed partial sterility. However, coppery leaf, variegated leaf, waxy leaf, white steak leaf, lanceolate leaflet, narrow-rugose leaflet, multiple leaflet, and wrinkled leaf were fertile
