1. Diploid and tetraploid races of Taraxacum kok-saghyz have been obtained by colchicine treatment. 2. Nineteen greenhouse-grown tetraploids had significantly larger roots but a lower rubber percentage than a similar number of greenhouse-grown diploids. Forty-three field-grown tetraploid plants had both significantly larger roots and higher rubber percentage than a group of thirty-six comparable diploids. Combined data from greenhouse and field tests show the tetraploids to have larger roots… CONTINUE READING
