Other claims from this paper (8)
- Observation Barley plant progeny of irradiated seeds showed 53% pollen sterility.
- Observation Barley plant progeny of irradiated seeds showed 71% ovule sterility.
- Observation The barley plant with sterility produced fewer mature seeds.
- Observation Meiosis of the barley plant showed two isochromosomes, more often associated with a ring of four chromosomes.
- Observation Somatic metaphase in leaf sheath meristems of the barley plant showed a few centromeric breaks.
- Observation A chromatid break in leaf sheath mitosis lent support to a deficiency of a small chromosome arm.
- Observation The liguleless-auricleless mutant was inherited as a single recessive trait.
- Mechanism The grass-like mutant is suspected to be due to the deficiency.
