Abstract

Abstract

Pollen staining, pollen and anther appearance, and anther size were observed in 18 genetic male sterile mutants in barley, Hordeum vulgare L. The stains used were 2,3,5-triphenyltetrazolium chloride (TTC), acetocarmine, and iodine potassium iodide. Stain uptake with the vital stain TTC was not a good indication of selfing ability, but nonstainability indicated sterility. To facilitate allelism studies four groups of mutants were delimited: A. Selfing ability-ms9; B. Near-normal pollen and anther development but no selfing-ms6, ms8, ms16; C. Extremely abnormal pollen and anther development- ms3, ms7; and D. Variable pollen and anther development-ms1, ms2, ms4, ms5, ms10, ms11, ms11az, ms13, ms14, ms17, ms18, ms19. The two allelic mutants, ms11 and ms11az, behaved differently for pollen stainability and appearance and for anther size.
