Large black spots develop on the leaf blades of nec32.bg plants and exhibit a slight increase in size as leaves mature. Older leaf blades showed more chlorosis around lesions and gradually they become yellow and died. The nec32.bg mutant is phenotypically similar to the nec27.ba (GSHO 3633, BGS 698) mutant, but it is not allelic (1).
Origin of mutant:
A gamma-ray induced mutant in Morex (CIho 15773) (1).
nec32.bg (γ08-130, GSHO 3639) in Morex (CIho 15773) (1).
