Abstract:

To investigate effects of genotypic and environmental on yield and scutellarin content of Erigeron breviscapus. Two new strains which through lines breeding were regional experimented of multi-point for many years. The variation coefficient of yield was 9.68%, higher variation coefficient of scutellarin content (5.15%). The genotypic effect of yield was 54.10% of total effects, and effects significantly (P<0.01), among point and among point×genotypic had effects significantly (P<0.05), but other effects had not significantly effects. The genotypic effect of scutellarin content was 78.28% of total effects, and effects significantly (P<0.01), among point had effects significantly (P<0.05), but other effects had not significantly effects. Conclusion: E. breviscapus had genotypic effects significantly, and can enhance scutellarin content and yield through variety breeding.
