soybean cyst nematode

Soil samples were collected from rotation and continuous resistant variety planting fields in Anda Institute of Utilization and improvement of Saline-alkali soil in 1995.Dynamics change of races of soybean cyst nematode were studied by Golden method.

1995年在安达盐碱土利用改良研究所的轮作和连种抗病品种地块取土样6份，用Golden方法进行大豆孢囊线虫生理小种变化动态监测。

This experiment took Kangxian 2 as female parent, which was highly resistant to No. 3 physiological strain of soybean cyst nematode and Hefeng 25 as male parent which had extensive adaptability and was the leading variety in Heilongjiang.

试验选用以高抗大豆胞囊线虫3号生理小种的抗线2号为母本，以适应性广泛的黑龙江省主栽品种合丰25为父本。
