Abstract
Seeds from two soybean varieties Glycine max (L.) Merr. A2522 and A3803 were irradiated with three doses of gamma rays: 100, 150, and 200 Gy in order to obtain high yielding and early maturing mutants to be grown after wheat in a two crop rotation. All three doses induced morphological variations and malformation that increased with the dose in both varieties. Coefficient of variation values were higher in M 2 than their respective values in M 3. The results showed no selection efficiency under the non-optimal environmental growing conditions with this lack of efficiency being more evident for yield than for early maturity. Using FTAB statistical programme 20 M 2 and M 3 plants were selected for each character in both varieties and, when evaluated in the following generations, it was clear that selection efficiency was higher for early maturity than for yield with that of the latter being higher in M 3 than in M 2 plants. Eventually, 6 high yielding and 10 early maturing M 4 mutants were obtained from both varieties. These promising mutants have to be grown in several locations and for several years before recommending them as potential varieties. (author). 14 refs., 4 figs., 25
