Recurrent parent

Using the big grain variety for backcross , the grain weight of B_3F_1 can be recovered to the same level as this recurrent parent .

用大粒品种回交，B3F1百粒重可以基本回复到轮回亲本的水平。

The zymogram of POD and EST of BC1were affected obviously by recurrent parent H.brevisubulaturn .

BC1代POD和EST同工酶谱明显地受轮回亲本野大麦的影响。

We found that the growth stage and important agronomic traits among most CSSLs seemed consistent with the recurrent parent in field experiment . 2 .

田间观察发现，多数代换系在生育特性和主要农艺性状上趋向轮回亲本。

The main economic traits of the recurrent parent could be basically recovered in BCz or BC1F1 ( BC2F1 ) generations .

轮回亲本的主要经济性状可在回交二代（BC2）或回交自交后代（BC1F1，BC2F1）中基本得到恢复。

Improved CMS line of Zao 49 was similar to its recurrent parent in economic traits with backcross generation , but it has severe selfed depression .

改良不育系从外部形态上接近轮回亲本，但是随着回交世代的增加衰退现象较为严重。

It was suggested that the effect of anther culture with B_1F_1 or B_2F_1 ( Japonica rice as the recurrent parent ) was better in Japonica rice breeding by the hybridization between Indica and Japonica rice .

初步明确利用籼粳交选育粳稻新品种时，应以粳稻作轮回亲本，从B1F1或B2F1中选株进行花培效果较佳。

On the other hand , in order to derive novel disease-resistant restorer lines , we use marker assisted selection to improve resistance property of smart materials and select materials both having genetic background consistent with recurrent parent and display disease-resistance in identification of disease-resistant experiment .

另一方面，我们利用分子标记辅助选择，对优良材料的抗性进行改良，选择遗传背景与轮回亲本一致同时在抗病鉴定中又表现抗病的植株，获得抗病的新恢复系。
