“…Leaf wetness, alternate hosts, weeds, crop debris and high planting density promote the spread of blast disease (Gashaw et al, 2014; Lule et al, 2014; Mbinda et al, 2021). Additionally, other fungal diseases that threaten finger millet production include banded sheath blight, caused by Rhizoctonia solani Kühn, and foot rot, by Sclerotium rolfsii (Nagaraja & Das, 2016; Patro et al, 2018). These pathogens exhibit distinct pathological races.…”

Finger millet is a climate‐resilient and highly nutritious small grain crop widely grown in the semi‐arid tropics. It has multiple uses, including for food, feed and beverage preparations. However, finger millet is an under‐utilized and under‐researched crop with a mean yield of <1.0 t/ha despite a potential productivity of up to 8 t/ha. The yield gap is attributed to several production constraints, such as biotic and abiotic stresses, a lack of access to improved seeds and production inputs and poor agronomic management practices. There are valuable genetic resources and genetic variability of finger millet in its centres of diversity and global gene banks for variety design, product development and commercialization. The genetic variability can be harnessed further to integrate essential traits into candidate varieties through conventional and modern breeding methods. Breeding and genetic innovations such as genomics‐assisted breeding, mutation breeding and genome editing would accelerate finger millet breeding and new variety design and deployment. The objective of this review was to document the opportunities, challenges and prospects of finger millet improvement as a guide for variety development and deployment with enhanced grain yield and nutritional contents. The first section describes global production status and yield gains, major production and productivity challenges in finger millet. This is followed by an in‐depth presentation on breeding and genetic progress on variety development with improved agronomic and nutritional quality traits, drought and salinity tolerance, and fungal diseases, weeds and insect pest resistance. Further, the review summarized finger millet's genetic and genomic resources, reference genomes, whole genome re‐sequencing and transcriptomics of finger millet technologies, genetic engineering and genome editing and their integration with conventional breeding methods for variety design with desired end‐use traits. The review provides foundational information to expedite the development of new‐generation finger millet cultivars with desirable product profiles, including high grain yield potential, early maturity, desirable seed colour, compact head type, food and feed nutrients quality and high marketability through modern breeding approaches.

The study was undertaken to evaluate the 490 finger millet (Eleusine coracana L.) genotypes (released, pre-release and breeding genotypes) including two check varieties viz., Indaf 5 (susceptible) and GPU-28 (resistant) against neck and finger blast disease at Hill Millet Research Station, Waghai, The Dangs, Gujarat during kharif, 2018 to 2022. Among all the 490 genotypes, 148 genotypes have shown resistant reaction under high disease pressure field conditions for neck and finger blast disease. However, 44 germplasm genotypes have shown consistent susceptible reaction during five years tested viz; kharif, 2018 to 2022. The genotypes viz., CFMV 2, GN-8, VL-376, PR-202 and GPU-67, showed the higher immune reaction under natural field condition. The pooled percent disease intensity of neck and finger blast diseases ranged from 2.90 to 72.4 per cent and 3.9 to 84.2 per cent respectively, in all tested genotypes including national and local checks. The resistant check variety GPU-28 exhibited resistant reaction to both neck and finger blast. In susceptible check variety Indaf-5 recorded the pooled diseases intensity of 61.74 % for neck blast and 73.6 % for finger blast. In which 72.4 and 84.2 is the highest percent pooled disease intensity of neck and finger blasts recorded in finger millet entry WN 666 which is the most highly susceptible reaction noted across five years of study in blast susceptible zone of Gujarat.

Millets gained a great attention at the global level in 2023 which is celebrated as the “International Year of Millets” to create awareness to eventually promote consumption and production. An attempt is made here to understand the cultivation and production dynamics of millets as influenced by their demand and supply. We also assess challenges and emerging opportunities to make millets more productive, competitive, and relevant to future farming. Millets registered a 60% decline in area and a 200% rise in productivity, but production has remained the same during the last seven decades. The demand of millets decreased as food due to greater incentives (purchasing grain at a pre‐determined price) and policies (distribution of grains to the public at a subsidized rate) in favor of wheat and rice. Millets would play a greater role in future agriculture due to challenges posed by climate change, limited water supply, and reduced agro‐biodiversity. This would need a much greater intensity of investment in millet research and adequate support as extended to wheat and rice. Increased emphasis on their genetic improvement and agronomic management is required to develop cultivars, using new tools and technologies, with high production potential and adequate environmental adaptation to make millets competitive with other crops. Mainstreaming the nutritional traits in millet breeding is also critically important to develop high‐yielding cultivars with improved grain quality traits. Promoting millet consumption would remain the key issue for increasing their demand as food, feed, and industrial raw materials through policies and awareness programs. Strengthening of value chain will help in diversifying agri‐food production system and creating an ecosystem for millet promotion.
