Analysis of Correlation and Path between Main Agronomic Characters and Plot Effective Yield of Rubus corchorifolius
Year: 2014
Type: article
Abstract: The correlation analysis,regression analysis and path analysis were carried out to study the relationships between main agronomic characters and plot effective yield of 8 varieties of raspberry(Rubus corchorifolius).The results displayed that the order of the correlation coefficient between various agronomic characters and plot effective yield was:average fruit weight number of lateral roots length of multi-year basal branches width of lateral roots width of taproots number of fruit branches width of multi-year basal branches average number of fruits per branch average number of basal branches per plant average yield per plant.The multiple regression equation was:y = 1.29 + 1.63x3-1.02x4-2.35x6-2.63x7+ 2.31x8+ 2.15x10.Path analysis showed that the number of lateral roots,average fruit weight and average yield per plant had direct positive effects on the plot effective yield of raspberry;the width of taproots,length of multi-year basal branches,and average number of basal branches per plant had direct negative effects;the width of taproots,length of multi-year basal branches,and average number of basal branches per plant could affect the plot effective yield through coordinating other characters.
