摘要

The assessment of genetic diversity in foxtail millet core collection can aid in the selection of best parents with complementary characteristics. It facilitates the introgression of favorable genes from plant germplasm into commercial cultivars and accelerates breeding progress. In this study, 595 foxtail millet landraces collected from Shanxi Province were subjected to a comprehensive assessment of 18 phenotypic traits. The results showed that the phenotypic diversity of foxtail millet genetic resources was abundant. Panicle weight (PW), grain weight (GW), primary branch number per panicle (PBNP), and spikelet number per primary branch (SNPB) showed abundant variation. Moreover, there were differences in foxtail millet genetic resources from different cities in Shanxi Province. The results of cluster analysis showed that the core collections were classified into three categories according to the geographical and ecological distribution of foxtail millet. The results of stepwise regression and principal component analysis (PCA) demonstrated that tillering capacity (TC), peduncle length (PeL), leaf length (LL), leaf width (LW), panicle length (PL), diameter of the main stem (DMS), panicle weight per main stem (PW), and protein content (PC) could be used as main identification indicators of the foxtail millet phenotypic variations. This research will benefit the identification and utilization of foxtail millet landraces and may help breeding values.
