Study of the genetic nature of induced mutations in peas


, : Study of the genetic nature of induced mutations in peas. Genetika 4(6): 13-21

The genetic nature of induced mutations in peas was studied by means of hybrid analysis. All the mutations studied were recessive. Frequent mutants with an abnormal stem differed from the initial cultivar in a number of other characters. The number of changed characters in 1 mutant can be 8-10. Such mutants differing in a complex of features are usually the result of a pleiotropic effect of the mutated gene. In crosses to the initial cultivar a 1:1 mono-hybrid segregation was observed in F2. Many mutations induced in various cultivars and forms are similar phenotypically. However, as it was shown that not all phenotypically similar mutations had the same genetic nature.
