Intra-category hybrids of Carthamus tinctoriuswere analyzedfor the genetic toxicityin detail for effect of Cd2++Cr6+on reproductive biology of Carthamus tinctorius.Five partially tolerant and five non-tolerant accessions of Carthamus tinctoriusafter screening were crossed to produce intra-category hybrid.These two heavy metals in combination Foundations influenced antagonistically first as well as second meiotic divisions inducing various kinds of anomalies and reduced the number of pollen bondage-kits grains per anther and significantly increased pollen sterility.

A differential response for the amount of meiotic irregularity was recorded between different treated sets of hybrids in (Cd+Cr) treated sets.This could be due to differential response of the genotypes for the same concentration of (Cd+Cr).These two heavy metals in combination reduced the number of pollen grains per anther and significantly increased pollen sterility.
