摘要
为全面分析中国春播早熟区高粱品种产量的稳定性和适应性,利用双标图对2020年在8个参试地点种植的17个具有代表性的高粱品种的丰产性、稳定性和适应性进行评价,并对产量及其构成因素进行相关性分析,为参试高粱品种在生产上推广和应用提供理论依据。结果表明:2020年,参试的17个高粱品种产量差异显著(P<0.01),‘吉杂163’产量最高,为9239.25 kg/hm^(2),其次是‘凤杂48’、‘赤杂131’(稳产性差)和‘吉杂170’,‘吉饲粱1号’产量最低,为7122.32 kg/hm^(2);高粱产量在试验地点间差异显著(P<0.01);除穗长外,高粱产量与穗粒数、枝梗数和千粒重呈正相关;‘吉杂163’、‘凤杂48’和‘吉杂170’在各个试验点具有较高的产量及稳定性,公主岭试验点最接近理想试验环境。
In order to comprehensively analyze the yield and its adaptability of sorghum varieties in spring-sown early-maturing areas in China,the yield,stability and adaptability of 17 representative sorghum varieties planted were evaluated by employing GGE biplot in 8 testing sites in 2020,and the relationship between yield components and yield was analyzed to provide a theoretical basis for the effective application of these sorghum varieties for the production for the promotion and application of the tested sorghum varieties in production.The results showed that,in 2020,the yield of the 17 sorghum varieties was obviously significant(P<0.01).’Jiza163’had the highest yield of 9239.25 kg/hm^(2),followed by’Fengza48’,’Chiza131’(had the poor stability)and’Jiza170’.The yield of’Liang No.1’was the lowest at 7122.32 kg/hm^(2);the yield of sorghum was obviously significant among the testing sites(P<0.01)except for spike length;the yield of sorghum was positively correlated with the grain number per pa-nicle,the number of branches and 1000-grain weight;’Jiza163’,’Fengza48’and’Jiza170’had the high yield and stability in each testing point,the experimental site in Gongzhuling was closest to the ideal environment.
