摘要 分析了2003-2010年全国审定棉花品种数量及棉花品种和种子监测数据,结果表明:在品种数量上,全国审定的品种和生产上种植的品种基本上都是逐年增加;在品种比例上,常规品种逐年降低,杂交棉品种逐年提高,优质专用棉品种也有较大幅度的降低;在种植面积比例上,常规品种逐年上升,杂交棉品种近两年迅速下降,优质专用棉品种也有较大幅度的降低;在种子技术水平上,生产用种使用毛种子的比例逐年下降,包衣种子比例逐年上升;在供种方式上,农民自留种已降到10%以下,统一供种的比例也明显降低,市场化程度约60%。转基因抗虫棉品种数量、占品种总数的比例、占种植面积的比例均逐年增加,美国培育的转基因抗虫棉品种所占的比例越来越小。
