Results:(1) The conchosporangia of brown yellow mutant was smaller and mature time was 15 days later than the parents. Thallus grew slowly in early stage, but average daily growth rate reached (7.50±1.18) cm after blade length was over 60 cm.(2)The emerald conchocelis were easy to mature and had special developmental mode that the spherulocytes can directly develop into sporangial branchlets and conchosporangia without thick conchocelis stage. Emerald blades were low in RPE with just (6.4710±0.0184) mg/g dry mass. The thallus grew quickly, average daily growth rate reached (11.95±2.33) cm after blade length was over 60 cm.(3) The conchocelis filaments of breen mutant were thin and short. Thallus grew slowly and had low contents of three phycobiliprotenin and chlorophyl.
