摘要： 省无538是用系谱法从早熟品系邯91与自育抗枯黄萎病桥梁品系207杂交后代中选育成的低酚棉花新品种。具有高产、优质、抗病、耐旱涝、成熟早、适应性广等优良特性。平均产量皮棉为1 179 kg×hm^-2，霜前皮棉为1098 kg.hm-2，相当于冀棉20号（常规棉）产量水平。单铃重5.3 g，子指10.6 g，衣分40.2%。其棉酚含量大大低于国际卫生标准（0.02%~0.04%）允许量，属高抗枯萎耐黄萎类型，适宜黄河流域棉区种植。同时对此品种进行了系列开发，用其生产的棉芽菜，其营养价值和味道均优于其他芽菜，棉芽菜生产技术已获得国家发明专利。

Abstract: Shengwu 538 is a glandless cotton variety derived from the hybrid Han91 line and 207 line using a pedigree selection method. It is characterized by high yield, fine quality, disease resistance, drought and water lodging tolerance, early maturation and extensive adaptability. Its average lint yield is 1179 kg/ha and Lint yield before frosting is 1098kg/ha, which is equal to that of Jimian 20 (normal variety). Single boll weight is 5.3g. Seed index is 10.6 g. Lint is 40.2 percent. The content of gossypl is much lower than that of the international hygiene standard (0.02%-0.04%). It is high resistant to Fusarium Oxysporum and tolerant to Verticillium dahiae. It is suitable for planting in the yellow river region. In addition, it has been developed to produce glandless cotton sprouts. It is better than other bean sprouts in nutrition value and taste. The glandless-cotton-sprouts technology has received the national patent.
