Soybean cultivar "Ludou 4" was inoculated with the AM fungus Glomus fasciculatus, soybean cyst nematode Heterodera glycines race 4 and the AM fungus plus SCN. A number of coefficients such as mycorrhizal colonization, SCN infection rate, activities of chitinase and PAL and transcripts of the genes Chibl(Chitinase b1) and PAL5 in soybean roots were assayed.

本研究系统分析了大豆(品种：'鲁豆4')接种AM真菌Glomusfasciculatum和胞囊线虫(SCN，Heterodera glycines)4号生理小种后各处理菌根和线虫侵染率、几丁质酶和苯丙氨酸解氨酶活性及几丁质酶基因Chib1和苯丙氨酸解氨酶基因PAL5转录物的动态变化。

随机选取30个F3代的株系，每个株系随机选取10～15个单株，进行上述孢囊线虫的接种鉴定，设抗感亲本作对照。8个株系抗病，18个株系分离和4个株系感病。F3代株系间的抗感分离比例确认兴县灰布支黑豆对大豆孢囊线虫14号小种的抗性是由3对基因控制、一对隐性和两对显性基因、隐性基因上位、两对显性基因互补的遗传假设是正确的。

Libellula and Xiannong 4 had different certain seeding resistances to rust, and Xiannong 4 could converge more races than Libellula.

里勃留拉和咸农4号均具有不同程度的苗期抗病性，咸农4号对小种的聚合作用大于里勃留拉。
