摘要
在棉铃虫常规饲养种群中发现一种成虫体色突变体,该突变体腹、翅颜色与野生型显著不同,用杂交试验对该突变体进行了研究。研究发现,突变体与野生型正反交F1代成虫体色均显示野生型色;F2代成虫野生型和突变体的分离比为3.23∶1;回交BC1代中野生型和突变体分离比为1.13∶1;F2代中的突变体自交,后代全部表现为突变。遗传分析结果表明,该成虫体色突变体属常染色体上单基因控制的隐性遗传性状。
A moth body color mutant was found in Helicoverpa armigera during regular feeding.Different color,compared with the wild type,mainly showed in abdoment and wing.Wild phenotype appeared in F_1 progenies when reciprocal cross of mutant with the wild type.Segregation ratio of 3.23∶1 in F_2 progenies and 1.13∶1 in backcross progenies was statistically counted respectively.Offspring entirely showed mutant type when F_2 progenies self crossed.Results indicated that this body colour mutant was monogenic autosomal recessive inheritance.
