【目的】对新疆甜高粱2008年区域试验中10个品种的13个农艺性状间关系进行研究。【方法】采用相关分析及主成分分析。【结果】产糖量与生物产量、茎秆产量、茎粗、单株重、秆重呈极显著相关,与生育期、锤度、株高、秆长和节数呈正相关,但未达到显著程度,与籽粒产量、穗粒重和相关性很小,与千粒重呈负相关;主成分分析结果表明,前3个主成分的累积贡献率是88.47%。【结论】在性状选择上,应选择植株高大、节数多、茎杆粗壮、生育期适中和锤度高的品种。
【Objective】 The objective of this study was to investigate the relationship among 13 agronomic traits of 10 cultivars in sweet sorghum in Xinjiang in 2008. 【Method】 Correlation analysis and principal component analysis were used. 【Result】 The results showed that there was a significant positive correlation between sugar yield and biomass, stem yield, stem diameter, plant weight and culm weight, but positively correlated with growth period, brix, plant height, culm length and node number but did not reach significant The degree of grain yield, grain weight per plant and kernel weight were small and negatively correlated with 1000-grain weight. The principal component analysis showed that the cumulative contribution rate of the first three principal components was 88.47%. 【Conclusion】 In the selection of traits, we should select the varieties with tall plants, more nodes, stout stems, moderate growth period and high brix.
