ABSTRACT
This study was conducted to find out the phytotoxic and mutagenic effects of heavy metals present in city waste water of B.D.A. colony, Bareilly. This water has different heavy metals such as cadmium (Cd) copper (Cu), zinc (Zn) and lead (Pb). The seeds of two varieties of Vigna radiata (L)Millsp. Viz Narendra mung-1(NM-1) and Pantnagar mung-2(PTM-2) were treated with 80%, 90% and 100% concentrations of city waste water and sown to raise M1 generation the phytotoxic and mutagenic effects of heavy metals were observed on different growth parameters. In M1 generation there was a marked reduction in all parameters. In M2 generation the viable and chlorophyll mutation were observed. Some selected mutants were sown to raise M3 generation and a significant increase in yield and protein content was observed with their resistant nature against city waste water.
