It was also found that the chromosomes paired well and formed a rod heteromorphic bivalent in the hybrid F1[73(36)9-1×CSDT 1BL]. Whereas 73(36)9-1 produced mainly configuration of 20''+1'+t' when test-crossed with CSDT 1BS. It showed that the translocation occurred on chromosome 1B short arm, and this segment came from rye chromosome 1RL. In the present paper we discussed also the way in which the translocation might be caused, and concluded that it was formed through reunion of two kind telocentrica (1BL and 1RL) after simultaneous misdivision of two univalent chromosomes (a wheat chromosome 1B, and a rye 1R).

同时还发现，73（36）9-1和"中国春"双端体的1BL能很好地配对并形成一个棒状的异形二价体，而它和CSDT 1BS的染色体则主要产生20+1′+t′的构型，从而证明易位发生的可能途径，推断是由于在F1花粉母细胞中的两个单价体（一个是小麦染色体1B，一个是黑麦染色体1R）同时进行错分裂之后产生的两种端着丝点染色体（1BL和1RL）重新并合形成的，因而冬小麦73（36）9-1可能是一个自发产生的易位系。
