Abstract:
The present study was carried out under three separate investigation in three parts. Part-I includes somatic karyotype, heterochromatin distribution and chromosome differentiation, and chromosome association and chiasma frequency under the head genomic composition. Somatic ka,yotypic analysis was carried out by quantitative method from selected dwmf plants of FrF6 progenies of seven single crosses involving six varieties/lines of hexaploid wheat (Triticum aestivum L.). Heterochromatin distribution and chromosome differentiation of six parental genotypes were studied by banding technique. A comparative study was made r to determine the effect of selection on the relationship between chiasma fequency and chromosome association of 12 Near lsogeneic Unes (Nils) from F6 populations of four crosses. ----
