5对因子的连锁数据表明，Z染色体长度为118个或更多单位m。暂定地图是Da. 39. D1. O8. D3. 35.D4. 37. D5。在G1， G1， G1系列中添加了第4个等位基因（G1），用于light flake。d4基因（无毛）降低生长速度和对拥挤条件的抗性。Darlington根据观察到的Lathyrus交叉频率计算出2条染色体的长度为148个交叉单位，4条为111个，1条为93个。如果细胞学和遗传学专家。是可比较的，d染色体连接大约覆盖了最长的两条染色体中的一条。
Linkage data for 5 pairs of factors indicate that the Z)-chromo8ome is 118 or more units m length. The provisional map is Da..39..D1..O8..D3..35.D4..37..D5. A 4th allele (G1), for light flake, has been added to the G1, G1, g1 series. The d4 gene (glabrous) lowers growth rate and resistance to crowded conditions.[long dash]Darlington calculates from the observed chiasma frequency of Lathyrus that 2 chromosomes are 148 crossover units in length, 4 are 111, and one is 93. If the cytological and genetic expts. are comparable, the D-chromosome linkage about covers one of the 2 longest chromosomes.
