Objective To evaluate the sensitivity of cell lines for poliovirus isolation in China National Polio Laboratory,make the China Sabin Master Reference(CSMR),and China Sabin Test Reference Strain(CSTR) for the whole laboratory network in China,which can be supplied to 31 provincial polio laboratories to test the sensitivity of the RD-A and L20B cell lines.

Prediction of grain protein based on canopy spectra in wheat with different plant types;

Method for digital design of crop plant type with high photosynthetic efficiency;

Preliminary study on plant type of wide adaptability super rice in South China;

Ten plant architecture traits were investigated in two years with this population.

Plant architecture or plant type is one of the key target traits for crop improvement, and the stem traits play leading roles in the formation of plant architecture.

The main goal of this study is to compare the difference between mepiquat chloride ( DPC) and mixture of DPC and DTA-6 in regulating the plant architecture traits and yield of insect-resistant transgenic cotton.

Study on quality index of high yield colony of different plant types of corn;

The results showed, the mutant has the characters of short upper leaf, without flag leaf, short plant types that comparing with Fuji Nigo, except the thousand kernel weight was lower than Fuji Nigo, other characters have no significant difference with Fuji Nigo.
