Breeding of a New Cassava Variety SC 8
The new cassava variety SC 8 (Manihot esculenta Crantz.cv.M.SC8) was selected by Tropical Crops Genetic Resources Institute of China Academy of Tropical Agriculture from the F1 clone self-crossed by the variety CMR38-120 introduced from Thailand. This new variety had higher yield and very wide adaptability as well as strong resistance to wind and high seedling-forming percentage. Its root yield is about 36.79 t/ha, an increase of 40.90% as compared with the check variety SC205. Its root dry matter content and starch content were 40.86% and 34.73%, an increase of 2.7% and 2.29% respectively as against the check variety SC205. The new cassava variety SC 8 is hence a good source for animal feed and industrial material with high yield and high quality. DNA fingerprinting was used to identify the new cassava variety SC 8 to protect this new variety and its property right.
