Large black spots develop on the leaf blades of nec31.bf plants and exhibit a slight increase in size as leaves mature. Older leaf blades showed more chlorosis around lesions and they gradually became yellow and died (1). Phenotypic expression of nec31.bf is similar to that of the nec27.ba (GSHO 3633, BGS 698) mutant (1).
Origin of mutant:
A gamma ray induced mutant in Morex (CIho 15773) (1).
nec31.bf (γ08-129, GSHO 3638) in Morex (CIho 15773) (1).
