The soybean apetalous mutant might have utility as a female parent in hybrid seed production for plant breeding studies.
The apetalous male-sterile soybean mutant may avoid this disease because it lacks petals.

Apetalous genotypes in Brassica species have different genetic origins.
The apetalous mutant ap-Tengbe was observed after several mutagenic seed treatments with EMS (Tengbe, 1990).
Plants with PDgr <10, 10 to 90, and >90 were classified into the groups of apetalous, partially apetalous, and normal-petaled genotypes, respectively.
Inheritance of apetalous flowers in a mutant of oilseed rape. (Crop Breeding, Genetics & Cytology)
They occur in Hamamelidae as a whorl alternating with antesepalous stamens, suggesting their homology with petals and as "a transitional stage between apetalous and petalous flowers" (Grepet & Nixon, 1996: 37).
Flowers are occasionally secondarily apetalous but may occasionally become secondarily petaliferous.
The flowers of Scytopetalaceae are basically apetalous but have a showy corona (pseudocorolla) of staminodial origin (Appel, 1996).
Staminodes: Their morphological and evolutionary significance
The most notable differences are found in the perfect flowers and uniseriate homocellular rays composed of procumbent cells in Asteropeia versus the apetalous flowers and uniseriate homocellular rays composed of mostly upright or square cells in Physena.
