Relative Dominance of Grain Weight in Wheat.

By Mrs. S. Boyce and R. W. Boyce, Botany Division, D.S.I.R.

Inheritance of grain weight in four Triticum crosses was discussed. In one case there is evidence of segregation for a simple recessive gene for high grain weight. In the remaining crosses high grain weight is either completely or partially dominant, number of genes segregating being indefinite.

This paper will probably be published in a genetical journal.
