“…The Shannon‐Weaver diversity index (SDI) (Shannon and Weaver, 1949) for each trait in domesticated and wild genotypes was estimated according to Bhattacharjee et al (2007) as follows:

SDI = (- \sum n_{i} = 1 P_{i} \times {log}_{e} P) / {log}_{e} n

where, n = number of phenotypic classes, P i = proportion of the total number of entries in the i th class.…”

To determine the natural variation for sucrose and raffinose fannily oligosaccharides (RFO) concentration in lentils {Lens culinaris Medik. ssp. culinaris), we analyzed a subset of 168 Lens germplasm lines from the ICARDA collection. Significant (P < 0.05) variations were found for sucrose, total RFO concentrations, and composition of the three main RFO (specifically raffinose, stachyose, and verbascose)

“…To overcome these problems, Frankel and Brown (8) proposed the establishment of a core collection (10% of the total) that could be selected from the existing collection of crop species resources in a gene bank. Core collections based on phenotypic data have been reported in several crops (3,27,28,32). Using passport information and data on 23 morphological descriptors, Upadhyaya et al (29) developed a core collection consisting of 155 foxtail millet accessions.…”

Identification of Blast Resistance in a Core Collection of Foxtail Millet Germplasm

et al. 2014

Blast, also known as leaf spot, caused by Pyricularia grisea (teleomorph: Magnaporthe grisea), is a serious disease affecting both forage and grain production in foxtail millet in India. For the identification of new and diverse sources of blast resistance, a foxtail millet core collection comprising 155 accessions was evaluated against the Patancheru isolate (Fx 57) of M. grisea. In a field screen during 2009 and 2010, 21 accessions were identified with neck and head blast resistance against Fx 57. In a greenhouse screen, 11 of the 155 accessions exhibited seedling leaf blast resistance to the same isolate. Further evaluation of the selected 28 accessions (found resistant to neck and head blast under field conditions during 2009 and 2010 or leaf blast in the greenhouse screen) against four M. grisea isolates (Fx 57, Fx 58, Fx 60, and Fx 62 from Patancheru, Nandyal, Vizianagaram, and Mandya, respectively) led to the identification of 16 accessions with leaf, sheath, neck, and head blast resistance to at least one isolate. Two accessions (ISe 1181 and ISe 1547) were free from head blast infection and showed resistance to leaf (score ≤3.0 on a 1-to-9 scale), neck, and sheath blast (score ≤2.0 on a 1-to-5 scale) against all four isolates. In addition, ISe 1067 and ISe 1575 also exhibited high levels of blast resistance. Blast-resistant accessions with superior agronomic and nutritional quality traits can be evaluated in multilocation yield trials before releasing them for cultivation to farmers.

“…For the past two decades, germplasm characterization at ICRISAT has led to the establishment of core and minicore collections for pearl millet (Bhattacharjee et al, 2007; Upadhyaya et al, 2009, 2011a), finger millet (Upadhyaya et al, 2006), and foxtail millet (Upadhyaya et al, 2008, 2011b) while only core collections was established for other small millets (Upadhyaya et al, 2014) ( Figure 1 ).…”

Nutritional insecurity is a major threat to the world’s population that is highly dependent on cereals-based diet, deficient in micronutrients. Next to cereals, millets are the primary sources of energy in the semi-arid tropics and drought-prone regions of Asia and Africa. Millets are nutritionally superior as their grains contain high amount of proteins, essential amino acids, minerals, and vitamins. Biofortification of staple crops is proved to be an economically feasible approach to combat micronutrient malnutrition. HarvestPlus group realized the importance of millet biofortification and released conventionally bred high iron pearl millet in India to tackle iron deficiency. Molecular basis of waxy starch has been identified in foxtail millet, proso millet, and barnyard millet to facilitate their use in infant foods. With close genetic-relatedness to cereals, comparative genomics has helped in deciphering quantitative trait loci and genes linked to protein quality in finger millet. Recently, transgenic expression of zinc transporters resulted in the development of high grain zinc while transcriptomics revealed various calcium sensor genes involved in uptake, translocation, and accumulation of calcium in finger millet. Biofortification in millets is still limited by the presence of antinutrients like phytic acid, polyphenols, and tannins. RNA interference and genome editing tools [zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeats (CRISPR)] needs to be employed to reduce these antinutrients. In this review paper, we discuss the strategies to accelerate biofortification in millets by summarizing the opportunities and challenges to increase the bioavailability of macro and micronutrients.
