摘要
为筛选出适合在湖南西部地区推广应用的饲用甜高粱品种,利用灰色关联度法对2020和2021年7个高粱品种的9个农艺性状指标进行综合评价.结果表明:不同品种间相比以阿尔托902的株高、茎粗、叶片数、叶长、叶宽、叶面积、单株鲜重、鲜草和干草产量均最高;不同年份间相比以2020年各高粱品种的平均株高、叶长、叶宽、叶面积、单株鲜重、鲜草和干草产量均较高,2021年各高粱品种的平均茎粗和叶片数均较高;年份×品种互作效应间相比以2020年阿尔托902的株高、叶片数、叶长、叶宽、叶面积、单株鲜重、鲜草和干草产量均最高,2021年阿尔托902的茎粗最高.综合评价结果显示,阿尔托902表现最优,生产性能最好,适宜在湖南西部地区推广应用.
Abstract
This study aimed to identify sweet sorghum varieties suitable for expansion in Western Hunan,China.Seven sweet sorghum varieties were evaluated based on nine agronomic traits using grey relational analysis in 2020 and 2021.The results showed that Alto 902 exhibited the highest values for plant height,stem diameter,leaf number,leaf length,leaf width,leaf area,fresh weight per plant,fresh yield,and hay yield compared to the other six sweet sorghum varieties.Significant year-to-year variation was observed,with 2020 demonstrating higher values for average plant height,leaf length,leaf width,leaf area,fresh weight per plant,fresh yield,and hay yield.Conversely,stem diameter and leaf number dis-played the highest average in 2021.The interaction effect of varieties and year also revealed Alto 902's superior performance in all traits except stem diameter,which peaked in 2021.Based on the comprehensive evaluation,Alto 902 demonstrated the most favorable agronomic performance across both years.These findings suggest its suitability for wider cultivation in western Hunan.
