Abstract
Autotetraploidy was induced in rahar by the application of colchicine. The tetraploid progeny was compared with the diploid parent for various qualitative and quantitative characters. The results show that gigas characters are not present in the tetraploid progeny, except for increased leaf and flower size. A study of meiosis in the tetraploid plant revealed a high degree of multivalent formation resulting in partial sterility. A daughter tetraploid plant was raised from this tetraploid and a study of meiosis in the daughter plant revealed its similarity to that in the mother.
