Crossing combinations of Soybean heterosis were stadied i n 1996～2000. The first yield test indicated that the soybean had clea r heterosis . At the same time, 161 comparative high-superiority combinatio ns selected by the test amounted to 80.9%in total. And 69 combinations are amang the high-superiority crosses in total with 34%.

经过1996～2000年5年的研究，共配制杂种优势测定组合199个，通过第一次产量鉴定表明，大豆具有明显的杂种优势，并筛选出F1超高亲、超对照优势率均为正值，且二者平均值大于10％的较强优势组合161个，占全部组合的80.9％。F1 超高亲、超对照优势率均大于20 ％的高优势组合69个占全部组合的34％。

Persons have been screened, 300 amblyopic children received standard rehab training and 10760 persons have been served with optometry. About one million people received the knowledge on eye health care.

现已完成视力筛查200978人，验光10760人，对300余名弱视儿童进行了规范的弱视训练，大约有100余万人不同程度接受了眼保健知识。

These studies indicate the rationality of our molecular design based on the crystal structure of KARI complex. To obtain more KARI inhibitors with high activities, the molecular docking and 3D-QSAR methods were applied to our further studying of these amidine compounds. Two methods AutoDock3. 0.3 and DOCK4. 0 were used in molecular docking, and the calculate results accord with that of herbicidal tests in general. The CoMFA model from 3D-QSAR analysis provided useful guidance for designing highly active compounds prior to their synthesis.

这些分子作为潜在的KARI抑制剂为基于KARI的农药分子设计提供了有利指导；对部分小分子进行了合成，在除草活性初筛的近三十个化合物中，个别化合物表现出较好的除草活性，其中一个化合物wb1596对油菜和稗草具有较高的生长抑制率，并通过E.coli KARI酶活性抑制试验验证了其KARI酶的作用靶标，此化合物可以作为KARI一个有苗头的抑制剂为后续工作奠定了基础；对发现的有苗头的KARI抑制剂进行了结构修饰和优化，合成了一系列脒类化合物并确证了它们的结构，改造后的化合物与原抑制剂相比大多除草活性相当或更佳，从而表明我们基于靶标结构的分子设计的合理可靠性；对所合成一系列脒类化合物进行了分子对接和三维定量构效关系研究。
