Genetic Analysis of Leaf Color Characteristics with Purple Genes on Chinese Cabbage(Chinese Cabbage×Purple Pakchoi)
摘要
Abstract
F1, F2, BC1 and BC2 generations were obtained through crossing, self-crossing and back-crossing by Chinese cabbage [ Brassica campestris L. ssp. pekinensis ( Lour ) Olsson ] of green leaves with purple pakchoi [ Brassica campestris L. ssp. chinensis ( L. ) Makino var. communis Tsen et Lee ] of purple leaves in order to study the genetic characteristics of leaf color. The results showed that leaf colors of F1 hybrid were purple, but its leaf colors were lighter than those of purple pakchoi. The ratios were close to 3 purple: 1 green for F2 progenies, 1 purple: 1 green for BC1 progenies. For BC2 progenies, all plants owned purple colors. The results of x2 test further proved that heredity of leaf color with purple genes on Chinese cabbage was controlled by one pair of gene. Purple genes were dominant genes compared with green genes and they showed addition effect.关键词
