Variety Source:

Hubei Huimin Agricultural Science and Technology Co., Ltd. used "(Jing 97046 × E Kang No. 9) F2" as the female parent and "Tai D-3" as the male parent to cross, and selected the regular cotton varieties bred by pedigree method. In 2015, it was approved by the Hubei Provincial Crop Variety Approval Committee, and the variety approval number is Eshen Cotton 2015003.

Quality Yield:　　

From 2012 to 2013, he participated in the regional test of cotton varieties in Hubei province. the fiber quality was determined by the cotton quality supervision, inspection and testing center of the Ministry of agriculture. the average length of the upper half of the fiber was 31.3mm, the specific breaking strength was 29.6 cn/tex, and the micronaire value was 4.4. The average yield of lint per mu in the two-year regional test was 90.73kg, which was 3.23 higher than that of the control Hubei anti-cotton 13. Among them, the per mu yield of lint in 2012 was 91.53kg, 5.04 higher than that of Hubei Kangmian 13. In 2013, the per mu yield of lint was 89.93kg, 1.47 higher than that of Hubei Kangmian 13.

Feature properties:

It is a transgenic Bt regular insect-resistant cotton variety. The plant type is compact, the permeability is good, the growth potential is strong, and the uniformity is good. The stem is thick, with sparse hairs. Leaves of medium size, leaf color green, bracts of medium size. Boll oval, medium size, boll tip protrusion weak, strong boll. In the regional test, the plant height is 128.0cm, the number of fruit branches is 13.7, the number of bolls per plant is 15.5, the weight of a single boll is 5.19g, the sample lint fraction is 39.16, and the sub-finger is 11.0g. The growth period is 103.0 days. The flower rate before frost was 86.8%. The resistance to diseases and insects was identified as resistant to Fusarium wilt, more resistant to Verticillium wilt, and resistant to cotton bollworm.

Cultivation points:

1, timely sowing. From the end of May to the beginning of June, the sowing density is generally 4000 plants per mu, and 3~4 seeds are sown in each hole. After emergence, the seedlings are timely seeded and replenished.

2. Scientific fertilization. Generally, 12kg of pure nitrogen is applied per mu, and the ratio of nitrogen, phosphorus and potassium is 1:0.5:0.8.

3, reasonable control. Following the principle of light before and heavy after, a small amount of many times, spraying 0.5-1g of antheramine per mu during bud period, 1.5-2g of antheramine per mu during flowering and boll period depending on the growth of cotton plants, and 4-5g of antheramine per mu within 7 days after topping.

4. Strengthen field management. Timely intertillage, ridging and soil cultivation, timely pruning, topping, pluck redundant buds, and timely irrigation in case of drought.

5, timely prevention and control of pests. Attention should be paid to the prevention and control of cotton bollworm, cotton aphid, red spider, blind stinkbug, Spodoptera litura, Bemisia tabaci and other insect pests.

Suitable range:

It is suitable for planting rape or wheat after harvest in cotton area of Hubei Province, and it is not suitable for planting in the places with serious diseases of Fusarium wilt and Verticillium wilt.
