“…This is because the AAs resulting from the breakdown of proteins during the fermentation process combine to produce a unique flavor (Katekan, et al 2011). The increase in FAAs after fermentation of soybeans results in functional benefits to the health of humans (Luo et al 2014;Shekar and Pushpendra, 2017).…”

The enzymatic activity (EA) and amino-type nitrogen (ATN), viscous substance (VS), organic acid (OA), free amino acid (FAA), and volatile compound (VC) content in fermented soybeans of six cultivars (Glycine max L. 'Taekwangkong' [TKK], 'Daechankong' [DCK], 'Misokong' [MSK], 'Seonpungkong' [SPK], 'Uramkong' [URK], and 'Chamolkong' [COK]) were compared.Fermentation increased the quality indices such as EA, ATN and VS in soybean, and their highest content were observed in DCK. The content of major OAs decreased in the following order: lactic acid > acetic acid > fumaric acid. The essential amino acid (EAA) content was increased by fermentation, and FAA production had a positive effect on the abundance of the fermentation metabolites γ-amino-n-butyric acid and ornithine. The content of the VS pyrazine differed with cultivar. Overall, soybean cultivars showed differences in the composition and fermentation properties, with raw DCK soybeans being particularly suitable for fermentation.

“…The development of high-yielding varieties depends on the availability of genetic diversity, which can be enriched by induced mutagenesis. The genetic diversity generated by induced mutagenesis has been reported in many studies that included faba bean (Nair and Mehta 2014;Shekar and Pushpendra 2017;Khursheed and Khan 2017;Singh and Sadhukhan 2019). However, most of these studies were based on morphology-based diversity.…”

Background: Although induced mutagenesis can rapidly generate genetic diversity, every genotype responds differently to different mutagen treatments in induceing genetic diversity. This study assesses and compares the genetic diversity of two mutant faba bean populations. Methods: Two genotypes representing landrace (Hassawi 2) and inbred variety (ILB4347) were exposed to gamma radiation and diethyl sulfate (DES). Two hundred eighty-two samples derived from individual 140 M2 mutant plants of Hassawi 2 and ILB 4347 and two parental lines were characterized using 11 Amplified Fragment Length Polymorphism (AFLP) primer combinations. Result: 89,820 bands within 2,083 polymorphic alleles were generated from the samples. Genetic diversity comparison of the mutant populations revealed that each genotype had varying responses to different treatments. The two genotypes had a relatively similar response to gamma radiation, while different responses were recorded in DES-derived mutant plants. Based on the Nei’s genetic distance, the populations were separated based on the genotypic origin. The population structure analyses showed that the Hassawi 2 and ILB4347 mutant populations were clustered into three and two groups, respectively. The difference in the number of clusters between the two mutant populations explains their breeding history. The present diversity considered as a valuable material used for breeding and conservation purposes.

“…However, breeding against these traits can potentially predispose these lines to other unforeseen problems. For instance, several studies on mutagenesis of leguminous crops show that some properties of the crop can be altered after the change (Shekar 2017;Maganoba 2018;Singh and Sadhukhan 2019). Such changes may either be positive to bring more desirable qualities or negative and ranging from changing days to maturity, water retention or stress tolerance, pod shattering ability and even increasing susceptibility to pest attacks (Shekar 2017;Maganoba 2018;Singh and Sadhukhan 2019).…”

As a result, developing improved varieties of the crop must factor in the susceptibility of the crop pest due to unforeseen losses it can impose on production.…”

Abstract. Philip AA, Adu-Acheampong S, Addai IK. 2020. Short Communication: Response of insect foragers to four soybean mutant lines cultivated in savanna agroecology of Ghana. Asian J Agric 5: 1-3. To increase soybean production, different lines have been developed with improved qualities to withstand problems associated with the production process. However, such development can render the lines (e.g., mutant lines) susceptible to pest attacks. We sampled for insect abundance and diversity within four soybean lines (150Gy, 200Gy, 250Gy, 300Gy) cultivated under two levels of NPK-15-15-15 fertilizer to check if mutagenesis has increased their attraction to insect activities including pest attacks. Some of the species recorded were Acanthacris ruficornis, Apis mellifera, Spodoptera frugiperda, Helicoverpa armigera, Bemisia tabaci, and Callosobruchus spp. The study also realized that NPK-15-15-15 had no significant impact on insects recorded within the various mutant lines. This only translates into no special pest attraction due to mutagenesis of not for any line. We recommend from this study that farmers should not have any reservation for cultivating any recommended mutant line for mass production after all other tests are completed on them before release.
