Other claims from this paper (11)
- Observation X-raying barley seeds yielded 34 chromosomal interchanges.
- Observation Pollen abortion in one-ring barley lines ranged from 14 to 58 percent, averaging 28.8.
- Observation No line with rings and no pollen abortion was found among the limited lines examined.
- Method / resource Homozygous interchange stocks were established for 28 of 34 barley lines.
- Method / resource A five-interchange tester set was demonstrated for identifying chromosomes in new interchanges.
- Observation Trisomics occurred among progeny of barley plants heterozygous for an interchange.
- Observation The barley g chromosome carries the large satellite.
- Observation The e chromosome carries linkage group IV.
- Observation The f chromosome carries linkage group V.
- Observation The b chromosome carries linkage group III.
- Method / resource Interchanges were shown useful as markers to locate new genes.
