Antiandrogens in the environment which are members of the cabbage family. The compound N-butylbenzenesulfonamide (NBBS) isolated from the bark of "Prunus africana", the Subsaharan red stinkwood tree, is a specific androgen antagonist and has been used as alternative medicine in benign prostatic hyperplasia. Licorice, or "Glycyrrhiza glabra" native to southern Europe, India, and parts of Asia has shown antiandrogen activity in male rats. Antiandrogens in the environment Antiandrogens in the environment have become a topic of concern. Many industrial chemicals, including phthalates and pesticides exhibit antiandrogen activity in animal experiments. Certain plant species have also been found to produce antiandrogens. In animal studies, environmental
Selection methods in plant breeding based on mode of reproduction species where normal mode of seed set is through a high degree of cross-pollination have characteristic reproductive features and population structure. Existence of self-sterility, self-incompatibility, imperfect flowers, and mechanical obstructions make the plant dependent upon foreign pollen for normal seed set. Each plant receives a blend of pollen from a large number of individuals each having different genotypes. Such populations are characterized by a high degree of heterozygosity with tremendous free and potential genetic variation, which is maintained in a steady state by free gene flow among individuals within the populations. In the development of hybrid varieties, the aim is
