Acrotrisomic plants 4S4L (Tsuchiya and Hang, 1980) were crossed
with four genetic marker stocks. The results of F2 data are shown in Table
Table 1. F2 segregation data of the hybrids between
acrotrisomic 4S4L and several genetic marker stocks
According to the recent linkage map, the order of 3 genes in the long
arm of chromosome 4 (4L) is centromere (C) - lg 4 - br 2
- gl 3, and the gene f9 for chlorina is located on the short
The results shown in Table 1 suggest that the breakage has occurred
between lg 4 and br 2 in the long arm of chromosome 4.
The breakage point in 4 L will be measured with the aid of Giemsa banding
