“…The descriptive statistical parameters and the frequency distribution analysis of the F 5:6 lines (2 replications) was conducted as mentioned in Kulkarni et al [27]. Analysis of variance (ANOVA) and least significant difference (LSD) analysis was conducted using the general linear model (GLM) in the SAS software program [28] to identify the level of significant difference in the fatty acid concentration in F 5:6 lines.…”

A high ω‐6/ω‐3 fatty acid ratio in the soybean seed adversely affects human health. The objective of the present study was to improve the fatty acid biosynthesis to reduce the ω‐6/ω‐3 ratio by combining the FAD2‐1A and FAD2‐1B mutant alleles with α‐linolenic acid (ω‐3) related alleles from wild soybean. The F2 population comprising 2320 F2:3 lines developed from S08‐14717 × PI 483463 cross exhibited significant variation for fatty acid components. Of these, 114 lines were advanced to the F5:6 generation and genotyped for FAD2‐1A and FAD2‐1B alleles. The lines carrying mutant FAD2‐1A and FAD2‐1B alleles showed ~ 761 g kg−1 oleic, and ~ 50 g kg−1 linoleic acids, which reduced ω‐6/ω‐3 ratios to ~ 0.6. Conversely, the lines carrying FAD2‐1A or FAD2‐1B mutant alleles had 267 or 399 g kg−1 oleic, 327 or 471 g kg−1 linoleic, and 120 or 130 g kg−1 α‐linolenic acids concentration, respectively. The elevated α‐linolenic acid resulted in the reduction of ω‐6/ω‐3 ratios in the range 2.5–3.9. The present study demonstrated that combining FAD2 mutant alleles with α‐linolenic acid‐related alleles from wild soybean reduces the seed ω‐6/ω‐3 ratio.

“…The study utilized a cross of two cultivated soybeans differing in many traits, including root and shoot traits. However, wild soybeans ( Glycine soja ) have also been shown to possess alleles that can contribute positively to different agronomically important traits in cultivated soybean ( Ha et al, 2013 , 2014 ; Kulkarni et al, 2016 , 2017a ; Patil et al, 2016 ). Lee et al (2014) observed that some of the RILs from an interspecific cross of PI 483463 (a wild soybean accession, with thinner main stems and branches and good forage yield) and “Hutcheson” had higher feeding value than cultivated soybeans, which suggested that the wild soybean PI 483463 may have favorable alleles that could be utilized to improve forage traits.…”

Substantial improvements in access to food and increased purchasing power are driving many people toward consuming nutrition-rich foods causing an unprecedented demand for protein food worldwide, which is expected to rise further. Forage legumes form an important source of feed for livestock and have potential to provide a sustainable solution for food and protein security. Currently, alfalfa is a commercially grown source of forage and feed in many countries. However, soybean and cowpea also have the potential to provide quality forage and fodder for animal use. The cultivation of forage legumes is under threat from changing climatic conditions, indicating the need for breeding cultivars that can sustain and acclimatize to the negative effects of climate change. Recent progress in genetic and genomic tools have facilitated the identification of quantitative trait loci and genes/alleles that can aid in developing forage cultivars through genomics-assisted breeding. Furthermore, transgenic technology can be utilized to manipulate the genetic makeup of plants to improve forage digestibility for better animal performance. In this article, we assess the genetic potential of three important legume crops, alfalfa, soybean, and cowpea in supplying quality fodder and feed for livestock. In addition, we examine the impact of climate change on forage quality and discuss efforts made in enhancing the adaptation of the plant to the abiotic stress conditions. Subsequently, we suggest the application of integrative approaches to achieve adequate forage production amid the unpredictable climatic conditions.

“…Recent advances in molecular marker technology have facilitated allele mining and gene discovery to aid in the genetic dissection of key traits (Niu et al 2013;Asekova et al 2016b;Kulkarni et al 2016;Kulkarni et al 2017). Maturity is one such trait that has substantial significance in the development of cultivars suitable for the environmental conditions in Kazakhstan.…”

ABSTRACT Kazakhstan is an agrarian country with 270 million hectares utilized for animal and crop production. The foremost objective of the state agriculture programs in Kazakhstan is to achieve food security of country on the basis of competitive crop production. Demand for soybean as an oil crop and animal feed is steadily growing in Kazakhstan and hence soybeans can be a great attribute for food security in this region. Currently, over 90% of all soybean production is concentrated in one region (Almaty) because the crop is highly sensitive to photoperiod and temperature. The climatological conditions in majority of the region pose difficulties in growing the soybeans. In this review, we discussed the impact of the geographical and environmental conditions in enhancing the soybean cultivation in different parts of Kazakhstan. Additionally, we have taken an account of current status of soybean production and the barriers that may have great influence on the soybean yield. Because soybean is a short-day plant, the main role in its adaptation to areas in Kazakhstan is played by its E genes (maturity and flowering genes), the exploitation of which constitutes the primary challenge for the expansion of soybean cultivation. Besides, we have proposed candidate regions for soybean expansion, including Almaty, Zhambyl (south), East Kazakhstan and Kostanay (north). Expanding soybean production in Kazakhstan and in Central Asia could be addressed using competitive education, application of modern scientific methods and cutting-edge breeding technologies, appropriate financing, and productive strategies to develop superior cultivars with tolerance to abiotic stresses.
