在中灿３０３７初级三体９和初级三体１１的后代中分别发现了一株形态变异株。依据中灿３０３７减数分裂粗线期核型以及这两个变异株减数分裂粗线期、终变期及后期互的染色体联会特征，确定这两个变异株分别为第９染色体和第１１染色体的四体。
A morphological variant was found in the progenies of Zhongtan 3037 primary trisomy 9 and primary trisomy 11. Based on the pachytene karyotype at 3037 meiosis in Zhongcan and the characteristics of chromosome association at the pachytene, final and later stages of meiosis of these two mutants, the two mutants were identified as chromosome 9 and 9 11 chromosome four body.
