Cytomorphological character of Indian tetraploid S. nigrum (n = 24) and S. nodiflorum ssp. nutans (n = 12) were studied. The reciprocal cross pollinations were made and the sterile hybrids were obtained which were at triploid level (n = 18). Chromosomal sterility and cryptic structural hybridity play important roles in hybrid sterility and genetic distinctiveness of Indian tetraploid S. nigrum and S. nodiflorum ssp. nutans.
