Abstract EN
Soybean (Glycine max) productivity is adversely affected by drought stress worldwide, including Vietnam.
In the last few years, we have made a great effort in the development of drought-tolerant soybean cultivars by breeding and/or radiation-induced mutagenesis.
One of the newly developed cultivars, the DT2008, showed enhanced drought tolerance and stable yield in the field conditions.
The purpose of this study was to compare the drought-tolerant phenotype of DT2008 and Williams 82 (W82) by assessing their water loss and growth rate under dehydration and/or drought stress conditions as a means to provide genetic resources for further comparative and functional genomics.
We found that DT2008 had reduced water loss under both dehydration and drought stresses in comparison with W82.
The examination of root and shoot growths of DT2008 and W82 under both normal and drought conditions indicated that DT2008 maintains a better shoot and root growth rates than W82 under both two growth conditions.
These results together suggest that DT2008 has better drought tolerance degree than W82.
Our results open the way for further comparison of DT2008 and W82 at molecular levels by advanced omic approaches to identify mutation(s) involved in the enhancement of drought tolerance of DT2008, contributing to our understanding of drought tolerance mechanisms in soybean.
Mutation(s) identified are potential candidates for genetic engineering of elite soybean varieties to improve drought tolerance and biomass.
