Resistant to Fusarium wilt, tolerant to Verticillium wilt, resistant to cotton bollworm; HVICC fiber upper half mean length 30.3 mm, breaking tenacity 30.9 cN/tex, micronaire value 4.9, breaking elongation 6.7%, reflectance 73.9%, yellowness 8.1, uniformity index 85.3%, spinning consistency index 150.

Key cultivation techniques: (1) Sow in the Yellow River basin cotton region from April 10 to 20, with plastic film mulching in monoculture or seedling transplanting intercropped with watermelon, garlic, @#@245@#@ and other crops. (2) For ordinary plots, retain a seedling density of 3000 plants per mu. (3) Apply sufficient base fertilizer, increase phosphorus and potassium fertilizer, apply flower and boll fertilizer early and heavily, spray nitrogen-phosphorus-potassium compound fertilizer at the appropriate time, and supplement fertilizer on the leaves in the late stage. (4) For mepiquat chloride chemical regulation, grasp the principles of early application, multiple applications and appropriate amounts. (5) The second generation cotton bollworm generally does not need control in ordinary years, and the third and fourth generation cotton bollworm should be controlled with pesticides promptly at the peak hatching period of eggs; throughout the whole growth period, pay attention to controlling non-lepidopteran pests such as cotton aphids, red spiders and mirids.

Approval opinion: This variety has obtained the safety certificate for the production and application of agricultural genetically modified organisms (the genetically modified organism name is sGKz20 (Ruizao 816)), meets the national cotton variety approval standards, and has passed approval. It is a mid-maturing hybrid first-generation variety with insect-resistance genes, suitable for spring sowing cultivation in the Yellow River basin cotton region of central and southern Hebei, Shandong, eastern, northern and central Henan, Jiangsu, Anhui north of the Huai River, Tianjin, southern Shanxi, and the Guanzhong area of Shaanxi, and should be promoted strictly in accordance with the scope permitted by the agricultural genetically modified organism safety certificate.
