| 摘 要： | 利用系统育种的方法，以双价转基因抗虫棉SGK321为亲本，经过群体内连续单株选择育成棉花新品种石抗39。该品种产量、品质、抗病性以及主要农艺性状较选择亲本SGK321均有明显提高。表明在杂交育种方法作为主流育种手段的今天，系统育种方法仍是作物新品种改良的一条重要途径。

| Abstract: | The new cotton variety Shikang 39 was selected from the transgenic hybrid cotton SGK321. The yield, quality, disease resistance and agronomic characters were improved obviously compared with SGK321. The research showed that although the hybridization was the main breeding means at present, the system selection was an important way in crop improvement. |
