Cassava, commonly known as the “underground granary”, serves as the food staple for more than one billion people globally. Additionally, it is a prevalent and advantageous crop in southern China. Recently, the food security situation has intensified, leading to an increased emphasis on the utilization of cassava in China. Therefore, the breeding of new sweet cassava variety holds immense importance. In this study, using a self-crossing segregating populations and SNAP molecular marker assisted technology, a new sweet cassava variety, Gui 11 was bred. This variety exhibits a compact plant shape, with light yellow fleshy roots. The hydrogen cyanide content in its fresh tuberous root is 12.30 mg/kg, and it yield is 43.35 t/hm2, presenting 24.64% higher than the current main sweet cassava variety 'South China 9'. Additionally, the fresh tuberous root of Gui 11 contains 38.40% dry matter, 28.20% starch, 4.71% soluble sugar, and 1.80% crude fiber, and it displays moderate resistance to Tetranychus cinnabarinus. The successful breeding of Gui 11 exemplifies the effective utilization of molecular marker technology to assist in the selection of new cassava varieties through self-crossing segregating populations. This advancement offers technical and variety support for promoting the transformation and enhancement of the cassava industry.
