“…These results suggest that breeding of proso millet in specific regions has proceeded in isolation (Liu et al, 2016). Similar to Trivedi et al (2015), Liu et al (2016) observed abundant morphological variation in the Chinese accessions, but more molecular markers or different types of markers are needed to assess their genetic diversity. These Chinese gene pools could also be valuable to future proso millet breeding programs since some accessions and ecotypes could be suitable to particular regions in the PNW.…”

“…Scientists have examined the genetic diversity of proso millet accessions to investigate the genetic relationships among landraces, breeding lines and cultivars, construct phylogenetic trees and draw connections between genetic diversity and geographical origins. Several types of molecular markers have been used to estimate genetic diversity and relatedness in P. miliaceum accessions, including amplified fragment length polymorphism (AFLP) (Karam et al, 2004, 2006), random amplified polymorphic DNA (RAPD) (M’Ribu and Hilu, 1994; Colosi and Schaal, 1997), cleaved amplified polymorphic DNA (CAP) (Lágler et al, 2005), inter simple sequence repeats (ISSR) (Lágler et al, 2005; Trivedi et al, 2015), sequence related amplified polymorphism (SRAP) (Trivedi et al, 2015) and simple sequence repeat (SSR) polymorphic markers (Hu et al, 2009; Cho et al, 2010; Hunt et al, 2010, 2011; Rajput et al, 2014; Dvořáková et al, 2015; Rajput and Santra, 2016). More genetic diversity studies using SSR markers have been conducted compared to other PCR-based markers because SSR markers are (1) neutral, abundant, and evenly distributed in the genome; (2) more informative since they are co-dominant, multi-allelic, and have high polymorphic information (PIC); and (3) easier to reproduce and score (Rajput et al, 2014).…”

Proso Millet (Panicum miliaceum L.) and Its Potential for Cultivation in the Pacific Northwest, U.S.: A Review

Proso millet (Panicum miliaceum L.) is a warm season grass with a growing season of 60–100 days. It is a highly nutritious cereal grain used for human consumption, bird seed, and/or ethanol production. Unique characteristics, such as drought and heat tolerance, make proso millet a promising alternative cash crop for the Pacific Northwest (PNW) region of the United States. Development of proso millet varieties adapted to dryland farming regions of the PNW could give growers a much-needed option for diversifying their predominantly wheat-based cropping systems. In this review, the agronomic characteristics of proso millet are discussed, with emphasis on growth habits and environmental requirements, place in prevailing crop rotations in the PNW, and nutritional and health benefits. The genetics of proso millet and the genomic resources available for breeding adapted varieties are also discussed. Last, challenges and opportunities of proso millet cultivation in the PNW are explored, including the potential for entering novel and regional markets.

Neutral and functional marker based genetic diversity in kodo millet (Paspalum scrobiculatum L.)

Kodo millet (Paspalum scrobiculatum L.) is known for its high nutritive value, dietary fiber, antioxidant activity, as well as for drought tolerance. It is primarily grown as a grain in India and in Africa it is either cultivated or harvested in wild. Neutral-ISSR (inter simple sequence repeat) as well as functional-SCoT (start codon targeted) and SRAP (sequence-related amplified polymorphism) markers were employed for genetic diversity studies in 96 accessions of kodo millet collected from diverse regions of India. The genetic diversity parameters like average bands per primer, Polymorphic information content, Nei's gene diversity and Shannon's information index of 11.22, 9.69; 0.12, 0.11; 0.15 ± 0.14, 0.13 ± 0.13 and 0.26 ± 0.21, 0.22 ± 0.19 was observed with neutral and functional markers respectively. Neutral markers were showing higher values as compared to functional markers for the genetic diversity parameters as discussed. Structure based analysis placed all the accessions into four sub-groups not strictly according to their geographical locations. The accessions from Bihar followed by Karnataka were showing high diversity based on both the marker systems useful for designing exploration, conservation and germplasm enrichment strategies. Further, the set of diverse accessions selected based on these markers would serve as potential sources of unique alleles and may be exploited in future for enhancement and utilization of kodo millet germplasm. Usage of African gene pool and wild species for broadening the genetic base of Indian kodo millet was also suggested based on the present studies.

ABSTRACT. Araucaria angustifolia seeds are the basis for the rural economy in southern Brazil, and the species presents different botanical varieties. The objective of this work was to evaluate the diversity of physical, physiological and biochemical characteristics of Araucaria angustifolia seeds from local varieties: 'sancti josephi', 'angustifolia', 'caiova', and 'indehiscens'. Seeds were collected from the cities of Painel and Urubici in Santa Catarina State and tested for moisture content, 1000-seed weight, emergence, emergence speed index (ESI), root and shoot length, electrical conductivity, tetrazolium, soluble carbohydrates, and starch content. Among the varieties cited above, the angustifolia variety from Painel displayed a greater 1000-seed weight, ESI, electrical conductivity and shoot length. However, the sancti josephi variety displayed a lower emergence percentage, 1000-seed weight, ESI, root and shoot length, and carbohydrate content. In a cluster analysis, based on Euclidean distance, three groups constituting the sancti josephi, indehiscens, and caiova/angustifolia varieties were found. In conclusion, there is great diversity in A. angustifolia seeds. The angustifolia and caiova varieties displayed similar diversity, and their physiological quality was better than that of other varieties. Variety characterization allowed for the compilation of information regarding seed collection and use for seedling production and species conservation.Keywords: viability, vigor, carbohydrates, caiova, indehiscens, sancti josephi.Qualidade fisiológica e física de sementes de variedades locais de Araucaria angustifolia RESUMO. Sementes de Araucaria angustifolia servem de base para a economia de muitas famílias rurais do sul do Brasil e apresenta diferentes variedades botânicas. Este estudo objetivou avaliar a diversidade das características físicas, fisiológicas e bioquímicas de sementes de Araucaria angustifolia das variedades locais sancti josephi, angustifolia, caiova e indehiscens. Sementes foram coletadas nos municípios de Painel e Urubici -Santa Catarina e submetidas aos testes: grau de umidade, massa de 1000 sementes, emergência, índice de velocidade de emergência -IVE, comprimento da raiz e parte aérea, condutividade elétrica, tetrazólio, teores de açucares solúveis e amido. A variedade angustifolia de Painel apresentou maior massa de sementes e vigor pelo IVE, condutividade elétrica e comprimento parte aérea. Enquanto, a variedade sancti josephi apresentou baixa porcentagem de emergência, massa de sementes, IVE, comprimento de raiz/parte aérea e teores de açucares. Na análise de cluster baseada na distância euclidiana, verificaram-se três grupos formados pelas variedades sancti josephi, indehiscens e caiova/angustifolia. As variedades angustifolia e caiova apresentaram similaridade e melhor qualidade fisiológica. A caracterização destas variedades possibilitou obter informações que podem auxiliar na coleta e aproveitamento das sementes para produção de mudas e conservação da espécie.Palavras-chave: via...
