barren inflorescence barren inflorescence (recessive): A homozygous bif2-N2354, mutant ear showing barren patches on rachis and missing kernels. Probably the heterozgote under influence of more favorable genetic modifiers or G014itions will express a visible phenotype.

Barren inflorescence ear: A homozygous Bif1-N1440 mutant ear showing most florets missing along cob rachis.

Barren inflorescence heterozygous ear: Two ears of +/Bif1-N2001 mutant plants showing absence of florets from rachis, mostly from tip, and in elongated strip down the middle of the bottom ear.
