摘　　要：以11个谷子品种(系)为材料,采用相关分析和灰色关联度分析相结合的方法,对与产量相关的9个农艺性状进行综合评价。结果表明,谷子品种的10个农艺性状均存在显著差异,变异系数为2.00%~9.16%;单穗重、穗粒重和千粒重与产量呈显著正相关,株高与产量呈显著负相关;9个农艺性状对谷子产量影响大小依次为穗粒重、千粒重、单穗重、出谷率、穗粗、生育期、穗长、株高、出米率。说明谷子高产育种中应注重穗粒重、千粒重、单穗重优异种质资源的利用。DTOPSIS综合评价表明,谷子区试前三名与产量前三名排序一致,评价结果与区试结果一致,说明DTOPSIS可用于谷子新品种综合评价。Eleven millet varieties(lines)were used as materials,and nine agronomic traits related to yield were comprehensively evaluated by the method of correlation analysis and grey correlation degree analysis.The results showed that there were significant differences in the 10 agronomic traits of millet cultivars,and the coefficient of variation was 2.00%-9.16%.Weight per panicle,grain weight per panicle and 1000-grain weight were significantly positively correlated with yield,while plant height was significantly negatively correlated with yield.The effects of nine agronomic traits on millet yield were grain weight per ear,1000-grain weight per ear,single ear weight,grain yield,ear diameter,growth period,ear length,plant height and rice yield.These results indicated that high yield breeding of millet should pay more attention to the utilization of germplasm resources with excellent grain weight per ear,1000-grain weight per ear and single ear weight.The comprehensive evaluation of DTOPSIS showed that the ranking of the top three millet cultivars was consistent with the ranking of the top three in yield,and the evaluation results were consistent with the results of the district test,indicating that DTOPSIS could be used for the comprehensive evaluation of new varieties of millet.
