CLONAL PROPAGATION OF F1 HYBRIDS AS A TOOL IN GENETIC-STUDIES OF THE SOYA BEAN [GLYCINE-MAX (L) MERRILL]

A simple technique for the vegetative propagation of F1 hybrid soya bean plants is described. By growing 1- and 2-wk old cuttings, all treated with 1-naphtylacetic acid and the fungicide metalaxyl, average success rates of 18 and 34% respectively were obtained. Cuttings grown under a long-day regime for two months produced large numbers of F2 seeds to be used in genetic studies. This method reduced the time and effort necessary to obtain hybrid progeny. © 1990 Kluwer Academic Publishers.
