Forming Core Collections in Barnyard, Kodo, and Little Millets using Morphoagronomic Descriptors

Abstract

2673ReseaRch M illets, which are comprised of a number of C 4 smallgrained, annual cereal grasses including barnyard millet, kodo millet, and little millet have abundant within-species racial diversity. These species also differ in ploidy levels. The ploidy levels in barnyard millet range from tetraploid to hexaploid to octaploid, while kodo and little millets are tetraploids (de Wet et al., 1983;Wanous, 1990). Barnyard millet has two distinct cultivated species, the Indian barnyard millet [E. colona (L.) Link] and Japanese barnyard millet [E. crus-galli (L.) Beauv], each with two Abbreviations: CB, culm branching; CR%, coincidence rate; CT, culm thickness; DF, days to 50% flowering; FL, fruit length; FLBL, flag leaf blade length; FLBW, flag leaf blade width; FLSL, flag leaf sheath length; FW, fruit width; G × E, genotype × environment; GH, growth habit; H´, Shannon-Weaver diversity index; IL, inflorescence length; LLR, length of lowest raceme; LRL, longest raceme length; MD%, mean difference percentage; NBT, number of basal tillers; NL, number of leaves; NNPAI, number of nodes on primary axis of inflorescence; NRAT, number of racemes above thumb; NRI, number of racemes per inflorescence; NSIB, number of secondary inflorescence branches; OPAS, overall plant aspects score; PE, panicle exsertion; PH, plant height; PL, peduncle length; PP, plant pigmentation; TL, thumb length; VD%, variance difference percentage; VR% variable rate.

Variability for Productivity and Nutritional Traits in Germplasm of Kodo Millet, an Underutilized Nutrient‐Rich Climate Smart Crop

“…in). Therefore, this study selected a representative set of 200 kodo millet accessions from the 665 accessions conserved at the ICRISAT genebank using the cluster information that was used to constitute the kodo millet core collection (Upadhyaya et al, 2014), representing ?30% of entire collection, and 26, 37, and 48% of the races regularis, variabilis, and irregularis, respectively. Globally, >8000 germplasm accessions of kodo millet have been conserved in genebanks, and a majority are housed in India (Upadhyaya et al, 2015).…”

“…Neither is such information available for grain nutritional traits that could provide important insights to kodo millet researchers and prove useful in germplasm selection and multilocation testing, and even lead to their direct release as cultivars. Therefore, this study selected a representative set of 200 kodo millet accessions from the 665 accessions conserved at the ICRISAT genebank using the cluster information that was used to constitute the kodo millet core collection (Upadhyaya et al, 2014), representing ?30% of entire collection, and 26, 37, and 48% of the races regularis, variabilis, and irregularis, respectively. This study aimed to assess kodo millet germplasm for morphoagronomic and grain nutritional traits, to assess the association between agronomic and grain nutritional traits, and to identify high-yielding and nutrient-rich accessions for use in research to identify and/or develop suitable cultivars.…”

Biofortification in Millets: A Sustainable Approach for Nutritional Security

“…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 ).…”

Barnyard millet – a potential food and feed crop of future

“…For optimum and precise utilization of diversity for agronomic and nutritional improvement, a core collection representing 50 and 89 accessions has been developed by Gowda et al () and Upadhyaya et al (), respectively. Halaswamy et al.…”

“…For optimum and precise utilization of diversity for agronomic and nutritional improvement, a core collection representing 50 and 89 accessions has been developed by Gowda et al (2009) and Upadhyaya et al (2014), respectively. Halaswamy et al (2001) characterized the national collection and identified promising accessions for higher plant height (seven accessions), higher number of basal tillers (nine accessions), longer inflorescence (10 accessions) and early flowering (27 accessions).…”
