Introduction to the characteristics and traits of the cotton variety Han 368

Main characteristics and traits: The plant is tower-shaped and relatively compact. The plant height is about 79.8 cm, it is a medium-maturing variety, and the growth period is about 129 days. The number of fruiting branches per plant is about 12.4, the node position of the first fruiting branch is about 6.5, the number of bolls per plant is about 15.6, the boll weight is about 5.3 g, the seed index is about 9.8 g, the lint percentage is about 43.0%, and the pre-frost lint yield rate is about 94.1%.

Disease resistance: in 2002, resistant to Fusarium wilt and tolerant to Verticillium wilt; in 2003, tolerant to Fusarium wilt and tolerant to Verticillium wilt.

Yield performance: According to the results of the provincial spring-sown conventional cotton regional trial from 2002 to 2003, the average lint yields per mu were 96.7 kg and 94.6 kg respectively, and the pre-frost lint yields were 90.4 kg and 89.6 kg; in the 2003 production trial of the same group, the average lint yield per mu was 91.6 kg, and the pre-frost lint yield was 85.1 kg.

Key cultivation techniques: For film-mulched cotton fields, the sowing period is April 15-20, the planting density is 3000-4000 plants/mu, and when applying chemical regulation, the dosage should not be too large in the early stage, while it may be appropriately increased in the later stage.
