BGS 648, Multiovary 4, mov4

BGN  43:171
Stock number: BGS 648
Locus name: Multiovary 4
Locus symbol: mov4

Previous nomenclature and gene symbolization:

Multiovary 8 = mo8 (1).


Monofactorial recessive (1).
Location is unknown.


Spikelets of this partial multiovary mutant have two carpels, two anthers, and two lodicules. One of the anthers appears to have been converted to a carpel; however, this conversion does not occur in all spikelets. Spikelets with two carpels often set two seeds. Mutant plants are often difficult to identify (1).

Origin of mutant:

A fast neutron induced mutant in Steptoe (CIho 15229) (1).

Mutational events:

mov4.k (FN315, mo8, GSHO 3643) in Steptoe (CIho 15229) (1). Two other very similar mutants have also been isolated, mov.m (FN316, GSHO 3672) and mov.n (FN487, GSHO 3673), as fast neutron induced mutants in Steptoe (1). The mov.n has a higher frequency of multiovary spikelets and these spikelets set two kernels more often (1).

Mutant used for description and seed stocks:

mov4.k (FN315, GSHO 3643) in Steptoe.
