Other claims from this paper (5)
- Observation The heat-treatment apparatus gave very satisfactory results on self-fertilized zygotes of Marquis wheat.
- Observation Heat treatments at 42, 43 and 44 °C for 20 min induced chromosome doubling in 2% of wheat plants.
- Observation The resulting 84-chromosome wheat hybrid plant grew slowly and failed to produce any spikes.
- Observation A number of 42-chromosome plants of the same cross also failed to produce spikes.
- Observation Chromosome doubling by temperature treatments can be induced in Triticum x A. glaucum hybrids only with great difficulty.
