Genetic Relationship between Chinese Cabbage with Orange Color in Inner Head and Purple Color in Leaf
摘要
Abstract
F1, F2, BC1 and BC2 generations were obtained through crossing, self-crossing and backcrossing by Chinese cabbage ( Brassica campestris L. Ssp. Pekinensis ) of orange color in inner head with pakchoi ( Brassica campestris L. Ssp. Chinensis ( L. ) Makino var. Communis Tsen et Lee ) of purple color in leaf, in order to study the genetic relationship between inner head color and leaf color. Results showed that colors of Fi hybrids were non orange-purple colors. The ratios of 4 genotypes were close to 9 non orange-purple : 3 non orange-non purple : 3 orange-purple : 1 orange-non purple for F2 progenies. The ratio of orange-purple genotype ororPr- was close to 18.75%, of which was close to 6.25% for pure orange-purple genotype ororPrPr. For BC1 progenies, the ratios of 4 genotypes were close to 1 non orange-purple : 1 non orange-non purple : 1 orange-purple : 1 orange-non purple. For BC2 progenies, all plants owned non orange-purple colors. Results of X test deeply showed that the genetic relationship between inner head color and leaf color on Chinese cabbage and pakchoi was not linked, which controlled by 2 independent genes. Orange gene or was located on the end of chromosome 1 in Agenome. Purple gene was located on some chromosomes except chromosome 1, which or gene was located.关键词
