摘要
对３份马铃薯、番茄融合产物与马铃薯的回交二代ＢＣ２材料进行原位杂交，可以清楚地区分马铃薯染色体和番茄（外源）染色体，番茄染色体的数目为２～６条。其中２份材料６７３１－１９和６７３１－２４中番茄染色体的数目稳定，另一份材料６７３１－２２，其外源染色体数目不稳定。
The alien chromosome in the backcross progenies from patato tomato fusion was detected through In Sita hybridication. The number of tomato chromosomes detected in the three BC 2 progenies varied from two to six. In one plant, 6731-19, two tomato chromosomes were constantly observed in all cells. In an other, 6731-24, there were also constant 4 tomato chromosomes. But in 6731-22, The numbers tomato chromosome varied between four to six.
