Two recombinant wild-types, the ZGRW and the ZRGW were bred by reciprocal crosses of the green-type and the red-type pigmentation mutants of Porphyra yezoensis. They were cultivated to test the inheritance mode of yield and to measure the photosynthetic pigments content, red rot disease-resistance, color, luster and volatile sulfur compounds concentration. Standing crops and photosynthetic pigments content of gametothalli and color and luster of dried sheets were similar between the ZGRW and the ZRGW; therefore, these characters were governed by the nuclear inheritance mode. On the other hand, the resistance to red rot disease of gametothalli and dimethyl sulfide content of dried sheets were significantly different between the ZGRW and the ZRGW, so these characters were transmitted by the cytoplasmic inheritance mode.
Key words: color, inheritance mode, luster, photosynthetic pigment content, pigmentation mutant, Porphyra yezoensis, reciprocal crosses, recombinant wild-type, red rot disease resistance, volatile compound concentration, yield.
