1·Using WCR lines with CMS cytoplasm as female parent to develop new restorer lines by backcrossing.

以同质广亲和恢复系为母本转育新的恢复系。

2·The sprouting percentage of hybrid progenies was reduced by backcrossing with the resistant parents.

用抗性亲本回交可提高其后代的抗穗发芽性。

3·The near isogenic lines with Oleson did not affect the spikelet numbers and flag leaf length of backcrossing male parents.

奥尔森矮源近等基因系对回交父本的小穗数没有影响，对旗叶长影响比较小；

4·The detection of susceptible and resistant strain and their backcrossing heterozygosis with PCR in laboratory validate above presumption.

室内用抗性和敏感亲本及正交杂合子检测的结果验证了上述推测。

5·Heredity research of aubergine leaf character in Brassica napus was carried out by using the methods of crossing, self-crossing and backcrossing.

采用杂交、自交、回交方法对甘蓝型紫红叶色油菜进行叶色遗传研究。

6·High heritability traits such as grain number per panicle and weight per thousand grains can be improved synchronously by limited backcrossing in breeding procedures.

对于每穗粒数、千粒重等遗传力高的性状，可结合杂交育种工作采用有限回交同步改良。

7·For the best use of marker information in a marker aided backcrossing program for gene introgression, a stepwise marker genotyping and individual selection were suggested.

因此，为了在标记辅助回交育种中充分利用标记信息，应当分步骤鉴定标记基因型和选择个体。

8·The results from this study indicate that the use of backcrossing with a PCR-based DNA marker was useful in waxy wheat breeding. These partial waxy wheat lines can be used in field production.

研究表明采用回交转育与分子标记辅助选择相结合的方法，是培育农艺性状优良部分糯性小麦的一种非常有效的方法。
