Introduction of cotton varieties
The whole growth period of Xinqiu No. 1 is about 130 days. Good seedling emergence, strong growth in the early and middle stage, and good leaf function in the later stage. The plant type is compact. Fruit branches have high nodes, few superfluous buds, and are easy to manage. The yield is good, the boll setting is strong and concentrated, the boll is large, oval, and the boll weight is 6.4 grams. It is smooth and concentrated. The lint percentage is 41%, and the pre-frost flowering rate is 93.5%. High resistance to cotton bollworm, resistance to Fusarium wilt, resistance to Verticillium wilt, less crazy branches, easy to manage. The average yield per mu is about 400 kg. Generally, there are 3000 plants per mu of 2500mu.
