bibo:abstract
  • The aims of the work were to examine the variability induced by EMS(ethyl methanesulfonate) mutagenesis of soybean plants, and to isolate mutants altered in nodulation and other growth characters. Seeds of two soybean cultivars, 'Hwanggeumkong' and 'Baegunkong' were treated with 30 and 50mM EMS(pH 7.0) for 6 hours and were planted directly in the field. Field emergency of M₁ seed was averaged to be 61.0%, and frequency of plants with chlorophyll-deficient sectors of the first trifoliolate is about 0.7%. Regardless of varieties and does of EMS, M₁ plant injury at harvest was present in plant height, pod and seed number per plant when compared to those of original-type soybean plants. The M₂ variability of nodulation process induced by EMS treatment was found to be narrower than that of shoot dry weight. On the basis of the occurrence of chlorophyll-deficient plants, mutated cell frequency within M₁ seed ranged from 5.3% to 84.2%, suggesting that mutation frequency on the M₁ seed induced by EMS occurred partly and randomly regardless of varieties and doses of EMS. The putative mutant, which had more nodulation than original-type plant, was short in plant height. Sparse nodulating soybean mutant was lower in leaf chlorophyll content and showed reduced growth.
