A new aestival vegetable soybean variety,Tongdou-5,is selected from the cross between Haimencubai which has high quality(female) and Haixi(male) which has big seed,high quality,high yield and high resistance to disease.

The spatial distribution pattern and sampling technique of the soybean aphid,Aphis glycines Matsmura in vegetable soybean field;

There are appearance quality,nutrient quality,edible quality and sanitation quality in the sense of vegetable soybeans quality.

Vegetable soybean is mainly planted in south of China.

Occurrence regularity and control threshold of Aphis glycines in fresh soybean fields;

Plant densities of fresh edible soybean and its effects on agronomic traits were studied from 2004 to 2006.

By using four methods of adaptable and stable parameter,variation coefficient,high steady coefficient,and recurrence coefficient,this paper analyzed and evaluated the high-yield and stable-yield character of the fresh edible soybean varieties in Jiangsu regional test in 2005.
