The objectives of this research were to evaluate (1) the performance of soybean mutant lines under drought stress conditions, and (2) the genetic diversity and relationship among the mutant lines using SSR markers. The field evaluation was conducted during the dry season of 2011 and 2012 at the experimental Farm of Mataram University, West Nusa Tenggara, Indonesia. The field experiment was set up in a randomized block design. Ten mutant lines and two control varieties were evaluated in four replications. Genetic distance among evaluated lines were determined based on allelic diversity analysis using 40 simple sequence repeat (SSR) loci. Under drought stress conditions, two mutant lines, Kdl3 and Kdl8, showed a better performance compared to the other ones. The high yielding mutant lines were Kdl3 and Kdl8, which yielded 1.75 t ha-1 and 1.69 t ha-1, respectively, compared to the parent and national control, Panderman 1.43 t ha-1 and Muria 1.32 t ha-1. These mutant lines required 30.75 to 32 days to flower and 79.75 to 83.75 day to harvest with relatively short plant height 28.25 and 23.35 cm respectively. Those mutant characters were better than those of the other three mutants, the original parents, and the control soybean species. Since the evaluated soybean mutant lines yielded more under drought stress conditions than the standard varieties, they can be used and registered as drought-tolerant soybean mutants. Moreover, the evaluated soybean accessions showed a wide genetic distance. The accessions were clustered into two groups according to their genetic background, namely group I (the Panderman with three mutant lines) and group II (the Muria with two mutant lines). Twenty-three out of 40 evaluated SSR loci,

“…Linkage mapping for QTL detection requires robust drought-tolerant donors. Yuliasti et al [119] evaluated five mutant lines along with their parents for drought tolerance and found nine SSR-markers viz., MBSS R033; satt137; MBSSR008; MBSSR203; MBSSR013; MBSSR021; MBSSR016; MBSSR136; and DMBSSR013 linked to drought stress tolerance. A recent report by Liu et al [120] describes the linkage of SSR loci associated with drought tolerance through linkage mapping.…”

Drought stress is considered a severe threat to crop production. It adversely affects the morpho-physiological, biochemical and molecular functions of the plants, especially in short duration crops like mungbean. In the past few decades, significant progress has been made towards enhancing climate resilience in legumes through classical and next-generation breeding coupled with omics approaches. Various defence mechanisms have been reported as key players in crop adaptation to drought stress. Many researchers have identified potential donors, QTLs/genes and candidate genes associated to drought tolerance-related traits. However, cloning and exploitation of these loci/gene(s) in breeding programmes are still limited. To bridge the gap between theoretical research and practical breeding, we need to reveal the omics-assisted genetic variations associated with drought tolerance in mungbean to tackle this stress. Furthermore, the use of wild relatives in breeding programmes for drought tolerance is also limited and needs to be focused. Even after six years of decoding the whole genome sequence of mungbean, the genome-wide characterization and expression of various gene families and transcriptional factors are still lacking. Due to the complex nature of drought tolerance, it also requires integrating high throughput multi-omics approaches to increase breeding efficiency and genomic selection for rapid genetic gains to develop drought-tolerant mungbean cultivars. This review highlights the impact of drought stress on mungbean and mitigation strategies for breeding high-yielding drought-tolerant mungbean varieties through classical and modern omics technologies.
