Abstract:
The systematic breeding method was adopted to breed a new good cultivar of Curcuma longa, named "Chuanjianghuang 1". From 2014 to 2015, two consecutive years of multi-point test were carried out in Shuangliu, Chongzhou and Wenjiang. The biological characters, phenology, agronomic characters, yield and quality indexes of "Chuanjianghuang 1" were comprehensively evaluated. The results showed that compared with local traditional species, the rhizome yield of the new cultivar "Chuanjianghuang 1" increased by 20.61%.The average content of volatile oil was higher than 24.17% and the average content of curcumin in root tuber was higher than 26.62%. The yield of root tuber increased by 54.59%.The average content of volatile oil is higher than 36.28% and the average content of curcuminoids is higher than 25.31%. Compared with "Huangsi Yujin 1", "Chuanjianghuang 1" increased the average yield of rhizome by 123.68%,the volatile oil increased by an average of 7.69%and the curcumin content increased by an average of 58.23%. The average content of volatile oil is higher than 52.82% and the average content of curcuminoids in root tuber was higher than 38.34%. The new variety "Chuanjianghuang 1" has better yield than the local traditional species, and the internal quality of rhizome and root tuber is better. Compared with "Huangsi Yujin 1", the yield of rhizome is significantly increased, and the internal quality of rhizome and root tuber is better, especially the content of curcumin in rhizome and curcuminoids in root tuber is significantly higher than that of "Huangsi Yujin 1". "Chuanjianghuang 1" is high yield, good quality, good stability and strong adaptability, which is suitable for cultivation and promotion in Chengdu Jinma River Basin, such as Shuangliu, Chongzhou, Wenjiang.
