日本松本、亮司等利用61个柑桔杂交组合的F_1代实生苗研究柑桔溃疡病抗性的遗传,F_1代分离比率表明,溃疡病抗性是由一对显性等位基因控制。日向夏、椪柑、温州蜜柑、土佐文旦等品种的基因型为显性纯合基因;香橙、甜春、请见、八塑、日本夏橙、克里曼丁桔、平户文旦的基因型为杂合基因;福原甜橙、葡萄柚和克来门特桔橙则为隐性纯合基因,在田间条件下,显性纯合体和杂合体品种的溃疡病抗性表现高抗至中感,而隐性纯合体品种表现为感病至高感。
Japan, Matsumoto Matsumoto, Bright Division and other 61 citrus hybrid combinations F_1 generation of seedlings of citrus canker genetic resistance, F 1 generation separation ratio shows that the ulcer resistance is controlled by a pair of dominant alleles. The genotypes of japonica, mandarin orange, satsuma mandarin and Tusanweidan were dominant homozygous; orange, sweet spring, see, eight plastic, Japanese summer orange, Is a heterozygous gene; Fuyuan sweet orange, grapefruit and Clementine oranges are recessive homozygous genes in the field conditions, dominant homozygous and heterozygous varieties of ulcer disease resistance to high resistance , While the recessive homozygous species showed the highest susceptibility.
