Introduction to the Cotton "Dong A" Genic Male Sterile Germplasm Resource
In 1972, a male sterile cotton plant was discovered in the field, and after 3 years and 6 seasons of research, the cotton "Dong A" genic male sterile germplasm was successfully developed. Its male sterility trait is mainly controlled by a pair of recessive nuclear genes. It has the characteristics of stable inheritance of male sterility, easy transfer, strong combining ability, a wide range of restorer lines, a population male sterile plant rate of about 50 percent, and 100 percent male sterility per individual plant. It also has good yield potential and wide adaptability. Using the Dong A genic male sterile germplasm, 1 derivative male sterile line was developed. Among them, several derivative male sterile lines were further combined and screened to produce 12 hybrid

Introduction to the Characteristics of the 9685B Cotton Variety
9685B is a new cotton variety with multiple resistance, no need for pruning, and ultra-high yield. I. Characteristics (1) Uniform and vigorous seedlings. Emergence is fast and uniform, seedlings are vigorous, and growth is steady. (2) No pruning, no disbudding. This variety is a medium-early maturing variety with a growth period of about 125 days. Plant height is about 90 cm, the plant type is relatively loose, fruiting branches are longer, leaf branches are few, leaf branches have strong boll-setting ability, and redundant buds are few, and they readily form fruiting branches and sub-bolls. Throughout the entire growth period, it can be left without pruning, disbudding, or removal of redundant buds, allowing it to grow naturally. It is suitable for large-scale planting
