Moench) landraces from\r\nNorth Eastern Ethiopia"^^ . "Understanding the pattern of genetic variability is an important component of germplasm collection and\r\nconservation as well as the crop’s improvement process including the selection of parents for making\r\nnew genetic recombination. Nine hundred seventy four sorghum landraces from North Eastern (NE)\r\nEthiopia were evaluated for agro-morphologic characters to assess geographic patterns of phenotypic\r\ndiversity and to identify whether there are specific areas of high diversity for particular traits. The\r\nShannon-Weaver diversity index (H′) for qualitative traits ranged from 0.30 to 0.93 (mean = 0.67) for\r\ngrain covering and grain color, respectively. The landraces also displayed highly significant differences\r\n(p<0.01) for all the quantitative traits with days to flowering ranging from 64 to 157 days (range = 93),\r\ndays to maturity from 118 to 215 (range=97) days, plant height from 115 to 478 cm; 1000-seeds weight\r\nfrom 18 to 73 g, and grain number from 362 to 9623. The first five principal component axes captured\r\n71% of the total variation with days to flowering and maturity, leaf number and length, panicle weight,\r\ngrain weight and number per panicle, panicle length, length of primary branches, 1000-seeds weight\r\nand internode length accounting for most of the variability. Cluster analysis grouped the landraces into\r\nten clusters. The clustering of zones and districts revealed close relationship between geographic\r\nlocations based on proximities and agro-ecological similarities. Differentiation analysis showed that\r\nmost of the landraces variability was within rather than between geographic origins of the landraces,\r\nindicating weak genetic differentiation among landraces from predefined geographic origins such as\r\npolitical administrative zones and districts. The weak differentiation might be due to frequent gene flow\r\nacross the study area because of seed exchanges among farmers."^^ . "2016-08-18" . . "11" . "33" . . "Academic Journals"^^ . . .
