Study on Adaptability of Hibiscus mutabilis Germplasm Resources in Chengdu Region

The adaptability of 171 Hibiscus mutabilis resources from 14 provinces were studied in Chengdu. The results showed that: (1) Most of the resources (80.70%, distributed in the south of 32°06'53"N) had good adaptability in Chengdu area. (2) Among the preserved resources, the proportion of single petal type (including single-petal red, single-petal white and single-petal white to red) was 57.25%, which was slightly higher than that of double-petal resources (42.75%). (3) 63.04% of the preserved Hibiscus mutabilis resources were firm, of which 62.07% were single petal and 40.23% were from Fujian. These results will be of great significance for the conservation and popularization of Hibiscus mutabilis germplasm resources.
