摘要
On the basis of the character "hairiness of rosette leaves," it was determined that the gl1-1 allele in homozygote state suppresses the manifestation of the dis-2-1 allele (dis2-1 < gl1-1); therefore, F-2 segregation is identified in a ratio of 9: 3: 4, typical for recessive epistasis. Inheritance of differences in hairiness of stem leaves corresponds to the Mendel scheme of segregation (9: 3: 3: 1) which is typical for dihybrids. Hairiness is absent on stems of triple recessive dis2-1, er-1, and gl1-1 plants, and segregation in F-2 is observed in the ratio of 9: 3: 4. A new line (Lug227) has been obtained on the mapping of mutant recessive genes dis2-1, er-1, and gl1-1.
