“…Finger millet can be grown in many agronomical regions, and the crop also has a higher shelf life making it economically viable (Onyango, 2016) [32] . Finger millets are used as a raw material for producing ethanol (Tekaligne et al, 2015) [45] . Soil salinity leads to hyperosmotic stress, and interferes with the various biological activities of plant roots and root microbes (Abbas et al, 2019) [1] .…”

Abiotic salinity stress affects the overall growth of plants. It is a major issue in arid regions of the world and semi-arid regions of the world. Physiological changes like germination percentage, root-shoot length, turgidity, and Relative water content were determined in 3 ragi varieties (Indaf, Hasiru gambe, and Carr ragi) with salinity treatments at a concentration (of 0, 50, 75, and 100 mm). Biochemical changes like concentration of Proline, reducing sugar, protein, and chlorophyll content were also measured in comparison to the control. Salinity was given as a basal dose and sampling was done after 21 days. The salinity treatment was started after 5 days of germination. Out of 3 varieties, Carr is found to be salt tolerant and Hasiru gambe ragi is found to be susceptible to salinity stress.

“…Given that new finger millet products such as bakery products, snacks, pasta, and sweet products are becoming increasingly popular, the demand for this crop is steadily increasing ( Onyango, 2016 ). Furthermore, finger millet is a raw material for ethanol production ( Tekaligne et al, 2015 ). The increasing global demand necessitates the development of advanced improvement techniques addressing complex attributes such as abiotic stresses that constrain its production.…”

Salinity stress is a major environmental impediment affecting the growth and production of crops. Finger millet is an important cereal grown in many arid and semi-arid areas of the world characterized by erratic rainfall and scarcity of good-quality water. Finger millet salinity stress is caused by the accumulation of soluble salts due to irrigation without a proper drainage system, coupled with the underlying rocks having a high salt content, which leads to the salinization of arable land. This problem is projected to be exacerbated by climate change. The use of new and efficient strategies that provide stable salinity tolerance across a wide range of environments can guarantee sustainable production of finger millet in the future. In this review, we analyze the strategies that have been used for salinity stress management in finger millet production and discuss potential future directions toward the development of salt-tolerant finger millet varieties. This review also describes how advanced biotechnological tools are being used to develop salt-tolerant plants. The biotechnological techniques discussed in this review are simple to implement, have design flexibility, low cost, and highly efficient. This information provides insights into enhancing finger millet salinity tolerance and improving production.

“…Due to its ease of cultivation, low fertilizer requirements and high adaptability, finger millet is considered a food security and major staple food crop for millions of subsistence and rural communities in semi-arid regions of Asia and Africa (Chivenge et al, 2015). Besides its direct use as table and feed stock, finger millet is also a candidate for the production of renewable plant products such as ethanol (Tekaligne et al, 2015). Compared to other cereals, finger millet has outstanding nutritional qualities as the grain is rich in calcium, phosphorus, iron, cysteine, tyrosine, tryptophan and methionine (Latha et al, 2005).…”

A simple and efficient plant regeneration system via direct organogenesis was established in finger millet using in vitro derived shoot apical meristems. Six varieties; GBK-043128, GBK-043094, GBK-043050, GBK-043137, GBK-043122 and GBK-043124 were evaluated. MS medium was used for cotyledonary germination. Maximum number of shoots (84.33%) was observed in variety GBK-043128 while GBK-043094 had the least germination efficiency (62. 67%). Shoot apical meristems from threeday old seedlings were evaluated for their potency of shoot induction on varied 6-benzylaminopurine (BAP) concentrations. Highest shoot induction was observed in medium supplemented with 1.75 mg/l BAP in GBK-043050 (3.00) whereas GBK-043094 (1.28) had the least response in medium supplemented with 1.0 mg/l BAP. To induce rooting, in vitro regenerated plants cultured on MS medium was supplemented with different concentrations of indole-3-acetic acid. The highest response in root induction, with a larger number of roots (10.28), was observed in MS medium supplemented with 4.0 µM IAA. Statistical analysis indicated that plant regeneration response varied greatly among the varieties. In vitro germinated plants were successfully transferred to the greenhouse after hardening, with 300 shoots developing into fertile plants, which were indistinguishable with wild type plants. This plant regeneration system has potential for production of transgenic finger millet crops.
