Germplasm Core Collection for Association Mapping\r\n\r\n"^^ . "Chickpea (Cicer arietinum L) is one of the most important cool season grain legume crops grown in semi-\r\narid tropics and Mediterranean regions. Terminal drought stress is one of the limiting factors for chickpea\r\nproduction. Utilizing of germplasm collections are the main gateway to improve the stagnant production\r\nof chickpea in semi arid tropics.\r\nHence, the objectives of this study were to i) Preliminary phenotyping and genotyping of germplasms\r\ncollections for diversity assessment; ii) Development of chickpea core collection based on diversity\r\nanalysis; iii) Identification of desirable accessions for drought tolerance from core set by proper\r\nphenotyping; iv) Large scale genotyping of the core collections by SNP markers; v) Large scale\r\ngenotyping of the core collections by SNP markers; vi) Identification and establishing marker trait\r\nassociations using appropriate association genetic approaches; vii) Quantification of population structure\r\nand relationship of Ethiopian chickpea collection.\r\nThe phenotypic evaluation in contrasting environment and SNP marker data analysis revealed that there is\r\nsignificant phenotypic and genotypic variability in Ethiopian chickpea germplasm for drought tolerance\r\nand other agronomic traits. The population structure and relationship analysis also revealed strong\r\nsubpopulation fixation and differentiation which was significantly different from the original population.\r\nHigh allelic and gene diversity were observed in the entire collection with common and rare alleles. Trait\r\nmarker association analysis showed markers which are strongly associated with maturity related traits and\r\nhigh linkage disequilibrium observed for the polymorphic markers.\r\nCore collection for Ethiopian chickpea germplasm were developed and validated for different validation\r\nparameters such as percent mean difference (MD %), percent variance difference (VD %), analysis of\r\nvariance, coincidence rate of range (CR %), variable rate of coefficient of variance (VR %) and genetic\r\ndiversity index. The result of validation showed better correspondence between the core set and the entire\r\nset which had avoided germplasm duplication and representing the whole collection economically in time\r\nand money with few numbers of accessions. Drought tolerant accessions were also identified in the\r\npreliminary field screening which needs further confirmation.\r\n"^^ . "2011" . . . .
