【Abstract】 Xiangnongmian No.8 was breeded by hybridization between Sb(AB-21) with nm-1. The Female parent Sb (AB-21) was selected from hybrid of variant of Simian No.2 and a big-fruit material from Hubei Province, and male parent nm-1 came from Nanjing Agricultural University.In 2003, Sbnm-7F1, a new hybrid combination with strong advantages and multi resistances. According to provincial regional test and multi-point and large-area production demonstration, and test and analysis by Cotton Quality Supervision and Testing Center of Ministry of Agriculture, and artificial identification of both blight and verticillium by Economic Crop Research Institute of Hubei Academy of Agricultural Sciences, Sbnm-7F1 possessed many characters, such as high yield and quality, great potential for yield increasing, wide adaptability, strong lodging resistance, blight resistance and verticillium ensurance, and so on. In this paper, the breeding process, characters and cultivation techniques of Xiangnongmian No.8 were introduced.更多还原
