backcross hybrid

基本解释

Gene expression of two Chinese cabbage backcross hybrid BC1, BC2 and their parents at bud stage was analyzed by means of cDNA-AFLP technique.
利用cDNA-AFLP技术对两种材料的不同回交世代BC1、BC2代与其亲本在蕾期的基因表达进行分析。
The double low variety used backcross male parent for double high GMS, the double low GMS had been bred through continuous backcross, at the same time, the double low hybrid has be en bred.
以现有的双低品种为回交父本，将双高核不育材料转育成双低核不育系，并已配制出了双低杂交种。
Two molecular methods were employed to successfully disclosed characters of the single hybrid zone: (1) this hybrid zone was composed of parental species, F1s, F2s and backcross derivatives;
我们通过分子测序和分子标记两种方法，揭示了该杂交区的性质：（1）该杂交区的构成是由亲本、F1代、F2代及回交后代组成；
