Assessment of molecular diversity using RAPD markers in elite genotypes of cotton (Gossypium hirsutum L.)

Author(s):
Suman Parre and Rajesh S Patil
Abstract:
The contemporary appraisal was to analyze eleven parental genotypes in cotton for their molecular diversity using RAPD markers so as to sort out the contrasting parents for developing mapping populations and study of different yield related traits for the development of varieties and heterosis breeding. Altogether 25 RAPD primers were utilized to contrast the parental genotypes out of which 15 showed transparent scorable distinct bands. Out of 15, 5 markers showed polymorphism and 10 showed monomorphism. Average number of bands per primer is 4.4. The genetic similarity coefficient ranged from 0.357 to 0.840 and the maximum dissimilarity of 0. 643. Clustering depicted that the 11 genotypes fell into two major clusters one formed by 8-1-2 genotype and the other include remaining 10 genotypes. Crosses between the genotypes based on their genetic distances which represent that genetic elements are in contrasting nature assist in creation of genetic variability and assist in hybrid breeding programmes.
