I. approval number

Su Shengmian 200608

II. Sources and types

Formerly known as "30", it is a medium-ripe upland cotton variety, which was bred in 2001 by 303/GK12 hybridization between Dafeng original Cotton seed Farm and Genesis transgenic Technology Co., Ltd.

III. Scope of adaptation

It is suitable for planting in mild disease areas of wilt and Verticillium wilt in Jiangsu Province (excluding Xuzhou).

IV. Yield level and characteristics

In the regional trial of Jiangsu Province from 2002 to 2003, the average seed cotton yield per mu was 248.1 kg, 29.0% higher than that of Simian 3, and 97.0 kg per mu, 14.3% higher than that of the control. In 2004, the average seed cotton yield per mu was 286.4 kg, 19.4% higher than that of Sumian 9, and 104.5 kg per mu of lint, 7.8% higher than that of the control.

The emergence of seedlings is general, the growth is strong, the plant is tall, the plant type is sparse, the stem is stout, the hairs are less, the leaves are larger, the leaves are dark, and the bolls are oval, large and fluffy. The average results of the provincial regional test were as follows: growth period 138days, plant height 108.68 cm, fruit branches 16.20 sets, bolls per plant 18.09, single boll seed cotton weight 5.76g, large sample lint percentage 39.22%, small sample lint percentage 39.55%, seed index 12.20g, pre-frost flowering rate 81.92%. The fiber quality has been tested by the Cotton quality Supervision, Inspection and testing Center of the Ministry of Agriculture (HVICC standard): fiber length 30.39mm, uniformity 84.55%, specific strength 30.64N / Tex, micronaire value 5.24,138 spinning evenness index. The average results of disease nursery identification were as follows: Fusarium wilt index 12.79, Verticillium wilt index 30.51. Resistant to Fusarium wilt and Verticillium wilt, close to high resistance to cotton bollworm.
