摘　　要：通过筛选适宜在山西省旱作丘陵区种植的酿造高粱品种,以集成丘陵旱作区高粱优质高效栽培技术。选取了12个高粱品种进行不同性状的相关性分析、主成分分析。结果表明,折合产量最高的是晋粱211,为10 560.85 kg/hm^(2),较对照品种高杂4增产8.35%;其次是晋杂44号,为10 502.12 kg/hm^(2),较对照品种高杂4增产7.74%;吉杂225排第3,为10 500.15 kg/hm^(2),较对照品种高杂4增产7.72%。晋杂44蛋白质含量最高(126.6 g/kg),高杂4脂肪含量(56.4 g/kg)和淀粉含量最高(773.8 g/kg)。相关性分析表明,主要农艺性状对产量的直接效应从大到小依次为出籽率、穗数、生育期、穗长、株高。通过主成分分析,将7个产量相关指标划分成3个主成分因子,第1主成分与鲜穗重、产量、穗数有关;第2主成分与穗粒数、出籽率、水分含量有关;第3主成分与千粒重有关。综合分析可知,晋杂51号、禾粱1号、晋杂44号、吉杂225、晋粱211和高杂4号适宜在山西省旱作丘陵区推广种植。In order to integrate the high quality and high efficiency cultivation technology of sorghum in the hilly area of Shanxi Province,the brewed sorghum varieties suitable for planting in the upland area were screened.12 sorghum varieties were selected for correlation analysis,and principal component analysis.The results showed that Jinliang 211 had the highest yield of 10560.85 kg/ha,which was 8.35%higher than the control variety Gaoza 4.The second was Jinza 44(10502.12 kg/ha),which was 7.74%higher than the control variety Gaoza 4.Jiza 225 ranked the third with 10500.15 kg/ha of yield,which was 7.72%higher than the control variety Gaoza 4.The protein content of Jinza 44 was the highest(126.6 g/kg),the ether extract content(56.4 g/kg)and starch content(773.8 g/kg)of Gaoza 4 were the highest.The correlation analysis showed that the direct effects of main agronomic traits on yield were seed rate,panicle number,growth period,panicle length and plant height in descending order.By principal component analysis,7 yield-related indexes were divided into 3 principal component factors.The first principal component was related to fresh spike weight,yield and spike number.The second principal component was related to grain number per spike,seed yield and water content.The third principal component is related to thousand-grain weight.The comprehensive analysis shows that Jinza 51,Heliang 1,Jinza 44,Jiza 225,Jinliang 211 and Gaoza 4 are suitable for spreading planting in the dry hilly area of Shanxi Province.
