| Abstract: | The methods of eliminating walls by enzymolysis,low osmosis and BSG were used to analyse the cell chromosome karyotype of mulberry variety 9204 (Luoyu 1×Xiqing 2) and its parents Luoyu 1 and Xiqing 2,the results are as follows:(1)The karyotype formula of 9204 is 2n=3x=42=36m+6sm;the karyotype formula of Luoyu 1 is 2n=2x=28=24m+4sm;the karyotype formula of Xiqing 2 is 2n=4x=56=48m+8sm.(2)The banding pattern formula of 9204 is 2n=42=4CIT+3CI+T ++3CIT ++3CI+T ++1T ++4CT ++2T ++10CT+8C+3I+1;the banding pattern formula of Luoyu 1 is 2n=28=2CIT+4CI+T ++1CIT+2CIT ++2T+1CT+2T+6CT+5C+2I+1;the banding pattern formula of Xiqing 2 is 2n=56=6CIT+7CI+T ++9CIT+12CIT ++3T+10CT+CT+3CT+2C+2T+2. |
