| 摘 要： | 从全国各地收集玉米自交系400份,在大田条件下初步进行了玉米耐低磷种质资源的筛选,研究了玉米自交系磷效率基因型差异。结果表明:①在低磷条件下,不同基因型玉米各性状间的差异大于高磷条件,而且耐低磷胁迫的能力具有较大的差异。②在两个供磷水平下,不同玉米自交系之间的产量都存在显著差异。中宗2号,太411,KH12耐低磷能力最强。从对磷的反应度来看,中宗2号,太411,187,58对供磷反应最大,而忻9005,KH12,XL12,冀257,冀35反应相对较小。 |

Selection of Genotypic Difference in Phosphorous Efficiency of Maize Inbredlines |
|
| Abstract: | Under low and high two soil P application levels, four hundred maize inbred lines used in China were selected to study phosphorus efficiency and related traits in the fields. The main results were summarized as follows:1.Genotypic differences which were found in many traits mainly on yield component at low P application level were larger than at high P and the ability in tolerance to low soil P was different.2.At two soil P application levels, significant variation was found in grain yield among maize inbreds. Zhongzong2,Tai411,KH12 were the most tolerant varieties to low soil P. On the other hand, Zhongzong2,Tai411,187,58 responded well to application on P fertilizer. However, Xin9005,KH12,XL12,Ji35,Ji257, were relatively low in responding to P applications. |
