“…The highly polymorphic EST-SSR markers resulted out 121 alleles with an average of 5.5 alleles per locus, which was comparable to other studies such as 4.91 in broomcorn millet, 4.79 in sorghum, 3.93 in rice, 8.2 in maize, 6.16 and 2.4 in foxtail millet, and 7.6 in sorghum (Cho et al, 2000;Agrama et al, 2007;Hu et al, 2009;Shehzad et al, 2009;Jia et al, 2009;Lin et al, 2012). The HE mean value in the present study (0.594) was higher than that reported in proso millet (0.37), while less than that reported in rice (0.67) (De campos et al, 2008;Cho et al, 2010). Similarly, the Ho average value (0.034) was slightly closer to Indian foxtail millet (0.045) (Gupta et al, 2012).…”

-Understanding the genetic variation among landrace collections is important for crop improvement and utilization of valuable genetic resources. The present study was carried out to analyse the genetic diversity and associated population structure of 621 foxtail millet accessions of Korean landraces using 22 EST-SSR markers. A total of 121 alleles were detected from all accessions with an average of 5.5 alleles per microsatellite locus. The average values of gene diversity, polymorphism information content, and expected heterozygosity were 0.518, 0.594, and 0.034, respectively. Following the unweighted neighbor-joining method with arithmetic mean based clustering using binary data of polymorphic markers, the genotypes were grouped into 3 clusters, and population structure analysis also separated into 3 populations. Principal coordinate analysis (PCoA) explained a variation of 13.88% and 10.99% by first and second coordinates, respectively. However, in PCoA analysis, clear population-level clusters could not be found. This pattern of distribution might be the result of gene flow via germplasm exchanges in nearby regions. The results indicate that these Korean landraces of foxtail millet exhibit a moderate level of diversity. This study demonstrated that molecular marker strategies could contribute to a better understanding of the genetic structure in foxtail millet germplasm, and provides potentially useful information for developing conservation and breeding strategies.

“…Following the publication of 25 microsatellite loci for P. miliaceum by Cho et al (2010), Hunt et al (2011) were able to use these markers to conduct analyses of 98 accessions of P. miliaceum landraces from across Eurasia in an attempt to elucidate the centre(s) of domestication of this species. Although the task was complicated by the tetraploid genome and lack of sequence data, their results showed two geographic clusters with either an eastern or western focus, with moderate genetic differentiation between the two groups.…”

(Poaceae), has been a crop in Asia and Europe for 10 000 years and for over 300 years in Canada, where it is grown for grain, rescue crops, birdseed, forage, and recently for swath grazing. Crop-like biotypes have escaped from cultivation throughout Canada, but these infestations were generally temporary. Probably the first persistent, weedy biotype in Canada (Quebec) has large, dormant, dark red seeds. Its eradication has been attempted for many years. In the 1970s, a worse problem, a black-seeded biotype with many weedy attributes, including shattering as seeds ripen and strongly dormant seeds distasteful to many birds, spread across southern Ontario and became labelled as noxious. Concurrently, it was described as the worst weed in the US Corn Belt. In the 1980s, Canadian studies revealed infestations of other weedy biotypes, differing in seed colour and other attributes. Panicum miliaceum is an extremely variable species world-wide. Since the late 1990s, weedy proso millet has declined dramatically after the adoption of newer herbicides, particularly glyphosate. This development may lead to increases in cultivated proso millet, especially where climate change favours short-season crops grown under drier conditions. Key words: weed biology, proso millet, Panicum miliaceum L., weed/crop, intraspecific variation, global distribution and history.Résumé : On cultive le millet, Panicum miliaceum L. (poacées), depuis 10 000 ans en Asie et en Europe et depuis plus de trois siècles au Canada pour ses graines, comme provende de secours, pour nourrir les oiseaux, pour son fourrage et, plus récemment, pour la paissance en andain. Des biotypes domestiqués sont redevenus sauvages un peu partout au Canada, mais les infestations restent le plus souvent temporaires. Le premier biotype envahissant persistant du Canada a probablement été observé au Québec. Il se caractérise par de grosses semences rouges dormantes. On s'est efforcé de l'éradiquer pendant de nombreuses années. Dans les années 1970, un biotype à graines noires, possédant de nombreuses caractéristiques d'une mauvaise herbe (notamment l'égrenage prématuré quand les semences parviennent à maturité et des graines à dormance prolongée que peu d'oiseaux aiment), a soulevé un problème plus épineux en se répandant dans le sud de l'Ontario. Ce biotype a été qualifié de nuisible avant de devenir la pire adventice dans la ceinture du maïs des États-Unis. Dans les années 1980, des études canadiennes ont révélé l'existence de peuplements d'autres biotypes envahissants, aux semences de couleur différente et présentant d'autres caractères. Panicum miliaceum est une espèce extrêmement variable dans le monde. Depuis la fin des années 1990, les variétés envahissantes ont diminué de façon draconienne avec l'apparition de nouveaux herbicides, particulièrement le glyphosate. Ce développement pourrait déboucher su...

“…The world's largest contribution to selections was in countries where common millet is most grown, such as India and USA (Manoharan & Sivasubramanian 1982, Baltensperger 2002, Karam et al 2004, Upadhyaya et al 2011. Crossing of various genotypes and examination of a large number of qualitative and quantitative indicators has been the subject of many studies (Barbeau & Hilu 1993, Zeller 2000, Heyduck et al 2008, Cho et al 2010, Hunt et al 2011. The aim of this study was to determine millet genotypes productivity for grain, based on regular and stubble crop on yield and individual agro-biological traits.…”

Summary: Agro-biological traits of common millet (Panicum miliaceum L.) genotypes were studied on experimental lots of the Institute of Field and Vegetable Crops in Bački Petrovac, Serbia in 2009 and 2010. The study included 16 genotypes of millet grown and used in selection programs in Serbia and abroad. Crops in trials were based on regular and stubble crops. A significant variability appeared during and at the end of growing season in the number of days from emergence to earing of some genotypes of millet, plant height, grain yield, 1000-grain weight and test weight of the test material, and it can be used as a good basis for further work on breeding and improvement of common millet. Cluster analysis identified genotypes with high performance for yield per plant, but also good stability of other studied parameters. Studies have shown that the genetic factor had significant effect on realized values of all tested traits. The difference between the yield of millet in regular and stubble crops was also statistically significant. Out of 9 varieties and lines of millet, 3 of them achieved a higher yield in stubble crops. From the point of agro-biological traits, 2010 was more favourable for the production of millet.
