Introduction to the New Cotton Variety Demian 206

This variety was developed by Denong Zhengcheng Seed Industry Co., Ltd.

Characteristics: Demian 206 is a new hybrid cotton variety with high quality, high yield and multiple resistance. The whole growth period is about 133-135 days, the plant height is around 129.5 cm, the fruiting branches are generally about 20.4, the bolls per plant are 42-48, the single boll weight is 5.7-6.2 g, the seed index is 10.9 g, the lint percentage is 42.35%, the staple length is 29.1 mm, and the general yield per mu is more than 120 kg, significantly higher than the control. Demian 206 has wide adaptability, high and stable yield, is relatively resistant to cotton bollworm and pink bollworm, resistant to fusarium wilt, and relatively tolerant to verticillium wilt.

Cultivation Techniques: Timely sowing: sow when the temperature steadily exceeds 14°C; generally choose to sow and raise seedlings in nutrient pots on a sunny day around April 15, and transplant in early May. Reasonable close planting: use about 300 g of seed per mu; plant 1400-1600 plants per mu in the field. Scientific fertilization: Demian 206 has strong boll-setting ability and a high fertilizer requirement, so apply sufficient basal fertilizer, heavily apply flowering and boll fertilizer, supplement with topping fertilizer, and increase potassium fertilizer. Strengthen field management: rationalize chemical regulation, balance and stabilize growth, appropriately increase the number of chemical regulation applications, and use an appropriate amount of chemical each time. Pest and disease control: pay attention to controlling cotton aphids, red spiders and mirids; insect-resistant cotton is not insect-free cotton, and attention should be paid to applying pesticides to control pests when the control threshold is reached.

Precautions: Sow with dry seeds. The progeny of this variety cannot be retained for seed use. Coated seeds and young seedlings are toxic, so safety should be noted.
