Analysis of Correlation and Path between Main Agronomic Characters and Plot Effective Yield of Rubus corchorifolius
摘要
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 a-nalysis 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 .关键词
