Bei 832 Rückkreuzungspflanzen des pentaploiden Bastards T. polonicum ×T. spelta zu beiden Eltern wurden die Beziehungen zwischen Chromosomenzahlen und Halmmarkigkeit sowie Ährendichtheit festgestellt. Die Ergebnisse stimmen mit denen der F₂-Studien überein (Matsumura, 1936 a).

(1) The material consists of 189 pairs of twins and 520 non-twin individuals. The number of ridges intervening between the four deltas at the bases of fingers I-IV have been counted and taken as the value of the individual.
(2) The coefficients of correlation between the right and left hands of the same individual are essentially the same for both monozygotic and dizygotic twins (nearly 0.9); the correlation between total values of both hands of A and B is nearly 0.9 for monozygotic twins, and only 0.5-0.6 for dizygotic twins.
(3) The polygon of the number of ridges constructed on a sufficiently larger number of individuals is approximately a normal polygon. This fact shows that the number of ridges on palms is determined by multiple factors which shows neither complete dominance nor recessiveness.

1) The chromosome numbers of 61 agronomic varieties or strains of Manchurian Kaoliangs were observed to be n=10 or 2n=20, and no polyploidy was found there. Meiosis proceeds normally in general.
2) In some agronomic varieties, one pair. of peculiar-shaped chromosomes which were termed by Huskins and Smith (1932) as A-chromosomes were identified in root tip cells.
3) All somatic chromosomes show a constriction at a point which is median or submedian. In some chromosomes another one constriction was also observed, but the further classification of chromosomes could not be made.
