"Phenotypic and genetic diversity in the foxtail millet\r\n(setaria italica (l.) p. beauv.) core collection)\r\n"^^ . "Foxtail millet core collection consisting of 155 accessions was evaluated at three\r\nenvironments for 12 qualitative and 13 quantitative traits to study the phenotypic diversity and to\r\nidentify trait specific accessions. Foxtail millet core collection was also molecularly profiled\r\nusing 84 SSR markers to study molecular genetic diversity, population structure and to identify\r\nSSR markers associated with the agronomic traits.\r\nIn REML analysis variance due to genotypes (σ2\r\ng) and genotype × environment (σ2\r\nge)\r\nwere significant for all the 13 quantitative traits. On the basis of phenotypic dissimilarity\r\nbetween pair of accessions, ten pairs of most diverse accessions were identified for breeding\r\nprogram for the developing high yielding cultivars with a broad genetic base and for the\r\ndevelopment of mapping populations. On the basis of pooled BLUPs (Best Linear Unbiased\r\nPredictors) of three environments, we have identified trait specific accessions for economically\r\nimportant traits such as yield and its traits contributing to yield (15 accessions for each trait).\r\nThese accessions could be used in recombination breeding to develop cultivars with desirable\r\ncombination of traits.\r\nThe SSR markers detected a total of 1,356 alleles with an average of 16.14 alleles per\r\nlocus. Of these, 368 were rare alleles; 906 common alleles; and 82 the most frequent alleles.\r\nSixty one unique alleles which were specific to a particular accession and useful for germplasm\r\nidentification were also detected. The genetic diversity of foxtail millet in this study was\r\ncorrelated well with racial classification and the race indica showed greater genetic distance\r\nfrom the maxima and moharia. Ten pairs of genetically most diverse accessions were identified.\r\nLarge molecular variation observed in core collection could be utilized effectively for selection\r\nof diverse parents for breeding cultivars and development of mapping populations. Mantel test\r\nshowed significant correlation between phenotypic and molecular dissimilarity matrix.\r\nThe STRUCTURE analysis provided the evidence for the presence of four\r\nsubpopulations. The mixed linear model (MLM) was used and the number of significant marker\r\ntrait association was 130 in E1, 69 in E2 and 106 in E3 at P≤0.05, whereas only 49 in E1, 23 in\r\nE2 and 61 in E3 were found to be highly significant MTAs at P≤0.01. In pooled BLUPs of three\r\nenvironments, a total of 108 MTAs were detected at P≤0.05. Of these 18 SSR markers showed\r\n37 significant associations at P≤0.01 with yield and yield contributing traits. Fifteen MTAs, that\r\noccurred in all three environments and overall in pooled data were identified as stable. Our\r\nresearch provided a first report of association study for yield and yield contributing traits in\r\nfoxtail millet using SSR markers. The results from this research also demonstrated the use of\r\ncore collection as association mapping panel to disclose marker-trait associations in foxtail millet\r\nfor yield traits that could lead to effective utilization of ex-situ conserved genetic resources."^^ .
