Chengdou No. 6 (soybean)
(1) Variety source: it is an early-maturing spring soybean variety bred by the Provincial Academy of Agricultural Sciences.
(2) characteristics: the growth period is about 103 days, which is 5 days earlier and later than that of the control. The plant height is about 55 cm, the podding habit is limited, the leaves are lanceolate, white flowers, gray hairs, mature pods are brown, the seeds are oval, the seed coat is yellow, the seed navel is brown, the weight of 100 seeds is about 17 grams, the seed protein content is 45.7%, and the fat is 19.61%. It mainly shows that there are many long grains in English, with the number of grains between 2.2 and 2.6 per English. Strong resistance to virus disease, high and stable yield, prosperous growth, good grain quality and good marketability. Poor resistance to barren.
(3) yield performance: the average yield per mu was 148 in the provincial soybean regional trial in 1992. 0 kg, 16.26% higher than that of the control, with an average yield of 141.2 kg per mu in 1993, an increase of 22.25% earlier than that of Dwarf. The average yield per mu in two years was 144.6 kg, which was 19.11% higher than that of dwarf.
(4) suitable planting area: suitable for planting in areas below 1000 meters above sea level in our province.

Chengdou No. 7 (8601-4) (soybean)
The main results are as follows: (1) Variety source: in 1986, Sichuan Academy of Agricultural Sciences used Bai Qian as the female parent and Chengdu Tiankandou as the male parent. (2) characteristics: this variety is a mid-mature spring soybean variety, and the growth period of spring sowing is about 120 days. Limited podding habits, white flowers, gray hairs. The grain is large (100 grains weigh about 26 grams), nearly round, seed coat yellow, navel yellow. The complete grain rate is high, with a protein content of 43.5% and a fat content of 20%. 7%. High yield, good quality, resistance to mosaic virus, lodging resistance

Super high yield, high resistance, high efficiency and early maturing soybean-Chaofeng 3
Chaofeng No. 3 soybean is a super high-yield, multi-resistance and high-benefit early-maturing variety selected by researchers in the Research Institute of Jilin Northern seed Company in the past 8 years. This variety overcomes the outstanding problems of high yield and poor harvest caused by large-scale application in the past, such as low yield, poor internal quality, not up to the national standard of high quality and easy to crack pods in dry years. It passed the provincial confirmation smoothly in March 2007. The growth period of Chaofeng 3 is 110d, and the active accumulated temperature is 2300 ℃ from sowing date to harvest.
