The application discloses a kind of resistance identification and
system breeding method of excellent strain of anti-
root rot Coptis, it is related to the technical field of medicinal
plant disease resistance identification and strain breeding, the application is first according to
pathogen composition,
inoculation body preparation,
seedling age, substrate treatment and environment window formation comparable batch group in
seedling inoculation stage, resistance observation
record generation group calibration
processing result is introduced into the same batch of
Coptis control strain, only allow comparable batch group to enter group screening in group calibration
processing result is effective state. In this way, the resistance observation
record that enters the same comparison chain meets the two prerequisites of consistent
inoculation condition and batch response effective simultaneously, batches of inoculation failure, inoculation too strong, control loss or control deviation anomaly no longer directly enter group retention set, so that the
disease level source of
Coptis candidate strain is constrained to the same inoculation pressure and the same observation prerequisite, solve the problem that the
disease level source of batches is inconsistent in front and back batches in multiple batches screening is directly combined and tabled.
