Genetic and Nutrient Analysis of New Pyropia yezoen-sis Strain“Huangyou No.1”
摘要
Abstract
Objective]New and high qualified Pyropia strains were screened to enrich the Pyropia strains resources in north China and provide fundamental data for their successful cultivation.[Methods]New strain of “Huangyou No.1”was obained by selective breeding of the wild germplasm from the farming ropes of Tuoji Island and cultivated in Nantong,Rizhao,and Tuoji Island,respectively.The genetic background (based on rbcL and COⅠ genes)and nutri-ent components (phycobiliprotein,chlorophyll a,carotenoid and soluble protein)were analyzed in “Huangyou No.1”from different farming areas together with its parent,the control stain of Pyropia yezoensis in Rizhao,the wild Pyropia from the shore of Tuoji Island and its cultivated offsprings.[Results]Based on the sequence of rbcL gene (about 1 200 bp),there were about 1.1% variation occurring in the population of the wild Pyropia growing on farming rope,com-pared to the other populations.All the other 6 populations had completely same rbcL gene se-quence.According to genetic diversity analysis ofCOⅠgene sequence (about 680 bp),only two cultivars(“Huangyou No.1”and Breeding 2)of Nantong had 2 bp difference,and the others were completely consistent.The nutrient content of“Huangyou No.1”cultivated in Rizhao was generally higher than the other cultivars and their wild germplasm,and the quality of seaweed cultivated in the Nantong was the lowest.[Conclusion]Based on the rbcL and COⅠ gene se-quence,most of the wild Pyropia on Tuoji Island were Pyropia yezoensis,and the nutrient compositions of the“Huangyou No.1”cultivated in different areas were superior to that of its wild parents.The results show that“Huangyou No.1”is more applicable for cultivation in the sea area of Rizhao.关键词
