Pearl millet (Pennisetum glaucum R. Br.) is an important staple and nutritious food crop in the semiarid and arid ecologies of South Asia (SA) and Sub-Saharan Africa (SSA). In view of climate change, depleting water resources, and widespread malnutrition, there is a need to accelerate the rate of genetic gains in pearl millet productivity. This review discusses past strategies and future approaches to accelerate genetic gains to meet future demand. Pearl millet breeding in India has historically evolved very comprehensively from open-pollinated varieties development to hybrid breeding. Availability of stable cytoplasmic male sterility system with adequate restorers and strategic use of genetic resources from India and SSA laid the strong foundation of hybrid breeding. Genetic and cytoplasmic diversification of hybrid parental lines, periodic replacement of hybrids, and breeding disease-resistant and stress-tolerant cultivars have been areas of very high priority. As a result, an annual yield increase of 4% has been realized in the last three decades. There is considerable scope to further accelerate the efforts on hybrid breeding for drought-prone areas in SA and SSA. Heterotic grouping of hybrid parental lines is essential to sustain long-term genetic gains. Time is now ripe for mainstreaming of the nutritional traits improvement in pearl millet breeding programs. New opportunities are emerging to improve the efficiency and precision of breeding. Development and application of high-throughput genomic tools, speed breeding, and precision phenotyping protocols need to be intensified to exploit a huge wealth of native genetic variation available in pearl millet to accelerate the genetic gains.

“…Pearl millet (Pennisetum glaucum) is a crop of economic significance in the semi-arid and arid regions of Africa and India where it is consumed as a staple crop by some communities (Govindaraj et al, 2020). Its grain zinc content is comparatively higher than in other cereals such as rice and wheat, however major concern is on the grain iron content produced by most pearl millet genotypes.…”

“…A target increment of +30 ppm iron was set by HarvestPlus to achieve a target level of 70 ppm iron in pearl millet grain from a baseline level of 47 ppm (Govindaraj et al, 2020). Germplasm screening by different institutions and researchers have revealed wide variability for iron across diverse populations that include landraces, inbred parents, population progenies and hybrids.…”

Genetic "biofortification" presents an opportunity to provide sustainable and cost effective solution to the perennial problem of 'hidden hunger' prevalent in most marginalized regions of the world. Diets in households across many developing countries typically consist of high calorie crops which are mostly cereals with limited diversified food. Production of cereal crops with elevated quantities of micronutrients needed by the human body is thus imperative. This review outlines "biofortification" of cereal crops with emphasis on existing genetic variability, genetic and molecular basis for essential amino acids, zinc and iron accumulation in crops. Key issues emerging are that in most crops there is scope to undertake conventional improvement given the sufficient variability influenced by additive genes or associated with polymorphic molecular markers. Availability of high potential noncommercialized genetically modified cereals points to prohibitive legislative frameworks and the need to adopt other tools such as gene editing, mutation breeding not subject to stiff restrictions. Furthermore, given the output nature of "biofortification" traits there is need to integrate this genetic enhancement in a pipeline breeding approach which integrates breeding objectives so that communities and processors can access these peculiar traits in every new improved variety.

“…The useful multivariate statistical methods are related to the relationship between related genotypes, as cluster dendrogram analysis that is an efficient tool that aimed to detecting the amount of genetic variance among genotypes under study based on their contributing traits and performance (Govindaraj et al 2020) and principal components analysis (PCsA), those have been widely used in variance study in germplasm groups of numerous species (Kumar et al 2020).…”

The presence of divergence in germplasm and its efficient utilization is essential for successful improvement of any fodder crop. During 2020-2021 summer seasons at Sids ARS. A total of ten pearl millet genotypes were grown with RCB design in three replicates to determine genetic variability, genotypic and phenotypic coefficients of variations, heritability, genetic advance and degree of linkage among various traits based on yield component, forage yield, and quality traits using cluster and principal components analysis (PCA). Results of combined analysis revealed significant differences among two years, genotypes and interaction of year x gen. for most traits. The genotypes (G2, G5 and G7) are promising and can be recommended in breeding programs due to revealing the highest yield components, forage yield, and quality values.The largest estimates of genotypic and phenotypic coefficients, high value of heritability connected with high value of genetic advance percent as mean were observed for most traits, indicating to existence of genetic variation beside efficient possibility selection for these traits. Results of cluster dendrogram analysis exposed a great genetic divergence among the tested genotypes, classifying them into 4 sub-clusters. The study detected six principal components (PCs) with Eigen values higher than 1.00 which, accounted for 90.027 % of the total variation for discriminating the 10-millet genotypes based on the studied traits. Therefore, these traits can be applied to selection criteria for yield improvement and determined appropriate genetic resource for efficient in pearl millet breeding program.
