中文摘要:
      为明晰濮花55号产量构成的关键要素,实现濮花55号的高产种植,本研究利用濮花55号在2017年国家北方片大粒组花生新品种多点试验中的数据,应用相关性分析、统计分析和主成分分析等方法,探讨濮花55号主要性状与产量的关系,并对其进行综合性评价。结果表明,濮花55号11个主要农艺性状和产量的变异系数为3.70%~36.92%,出米率变异系数最小,单株饱果数变异系数最大。濮花55号果数、仁数和出米率与荚果产量呈正相关,百果质量与荚果产量呈负相关,主茎高、侧枝长、总分枝数等农艺性状间也存在两两相关关系;对濮花55号荚果产量影响直接正效应最大的是果数和侧枝长,直接通径系数分别为0.938和0.879,直接负效应最大的是主茎高和结果枝数,直接通径系数分别为-0.513和-0.392。主成分分析将花生11个农艺性状降维为4个主成分,累积贡献率达79.952%,综合性分析结果表明,濮花55号在安徽固镇、山东临沂、山东菏泽、安徽泗县、山东济宁等地种植效益较好。本研究为濮花55号的高产栽培和品种推广提供了理论支撑。
英文摘要:
      To clarify the key factors influencing the yield composition of Puhua 55 and to achieve high-yield cultivation,this study employed correlation analysis,statistical analysis,and principal component analysis to investigate the relationship between the main agronomic traits and yield of Puhua 55. The results showed that the coefficient of variation for 11 main agronomic traits and yield of Puhua 55 ranged from 3.70% to 36.92%. The coefficient of variation for shelling percentage was the lowest,while the coefficient of variation for the number of full pods per plant was the highest. Pod yield was positively correlated with the number of pods per kilogram,the number of kernels per kilogram,and shelling percentage,but negatively correlated with hundred-pod mass. In addition,significant pairwise correlations were observed among agronomic traits,such as main stem length,branch length,and total number of branches. The strongest positive direct effects on pod yield were exerted by the number of pods per kilogram and branch length,with direct path coefficients of 0.938 and 0.879,respectively. Conversely,main stem length and the number of branches with pods had the most significant negative direct effects,with direct path coefficients of -0.513 and -0.392,respectively. Principal component analysis reduced the 11 agronomic traits to four principal components,with a cumulative contribution rate of 79.95%. Comprehensive analysis indicated that Puhua 55 demonstrated good planting benefits in Guzhen,Anhui ; Linyi,Shandong; Heze,Shandong; Sixian,Anhui,and Jining,Shandong. This study provides a theoretical support for the high-yield cultivation and extension of Puhua 55.
