The main results are as follows: (1) Variety source: the genic male sterile line anti-A1 used by the Provincial Academy of Agricultural Sciences was used as the female parent and was mixed with 12 groups of national popularized varieties cultivated by China Cotton Institute.

(2) characteristics: the whole growth period of the hybrid is 130-136 days, the plant height is 85-90 cm, the plant body is compact into a tower, the stem and branch are stout, the leaf color is dark green, the leaf is medium, the light transmittance is good, the growth is prosperous, the boll setting is strong, the boll is oval, the bell shell is thin, and the boll is smooth. The fiber is neat, good color, lint percentage 41-43%, boll weight 5-6 g, lint index 6.8-7.4 g, seed index 9.0-9.8 g, fiber length 29.5-30.5 mm, micronaire value 4.29, specific strength 20.78 g / Tex; resistance identification results; Fusarium wilt index 12.8-15. 9; Verticillium dahliae refers to 30.68-33.7, belonging to wilt-resistant and yellow-tolerant varieties. The yield of this combination is significantly higher than that of the control, and it is resistant to blight and yellow, has good fiber quality, and has higher yield of propagation and seed production.

(3) yield performance: in the provincial regional test in 1993-1994, the average lint yield per mu was 81.94 kg, 9.92% higher than that of Chuan 73-27; in 1995, the average lint yield per mu was 104.42 kg, 18.03% higher than that of Chuan 73-23.

(4) suitable planting area: suitable for planting in some cotton areas of the Yangtze River Basin and the Yellow River Basin.
