Absence of interspecific mating incompatibility is of advantage in programmes of breeding for evolving improved varieties of the crop with built-in-resistance. The first generation hybrids though do not produce viable seeds in profusion, are not totally sterile. The scanty viable seed recovery from the hybrids against the parents is suspected to be due to chromosomal differentation that could have taken place during speciation in the genusennullThesis
