The RT homozygotes, 10 lines of 108 (Pei-ko), 7 lines of 521 (Kissin) and 10 lines of 504 (Taichung No. 65) were tested in a randomized block experiment. Various agronomic characters which are controlled by p. olygenes were measured and variance analysis was made. It was found that the translocation lines are generally homogeneous in agronomic characters and may be regarded as having the same genotype for translocation. However, translocation may sometimes be accompanied by genic changes. It was assumed, further, that the translocation method may be used to some extent for locating quantitative charadters on chromosomes. Literature cited
