Abstract:
The experiment was conducted to study the mutagenic effects of space environment on summer soybean varieties Hedou 3，Meng91-413 and Meng 9609-1. The results showed that space environment led to the decline in seedling emergence rate of Hedou 3;In SP1 generation, comparing with control, the lowest pod height of Hedou 3 and infertile pods per plant of Meng91-413 and Meng9609-1 all increased;The number of effective branches of Hedou 3 were less than control. In addition, a plant with many stable mutation characters was obtained in SP1 generation of Hedou 3. There were 236 mutants of stem, leaf, branch, pubesence, growth stages, and fertility mutant of Hedou 3, and 66 mutants of stem, leaf, pubesence and growth stages of Meng91-413 in SP2 generation with the mutation rate of 2.74%and 0.59%. Meanwhile, in SP2 generation of Hedou 3 some mutants with many mutation characters were obtained from 2 lines.
