Correlation and regression analysis of fresh fruit bunch yield components in oil palm ( Elaeis guineensis)
摘要
Abstract
Oil palm is the most important oil crop all over the world, its production is 30%of the world' s total vegetable oil, but there is still room for improving the yield. In order to verify relationship among fresh fruit bunch yield compo-nents, correlation between fresh fruit bunch yield and other traits were studied by using correlation, regression and path analysis. The results indicated that fresh fruit weight, number of bunch were the most closely related with fresh fruit bunch yield. Moreover, breeder should focused on average weight of fresh fruit bunch, number of fresh fruit bunch in each plant, fruit length, fruit width and oil content of mesocarp, and balance interaction among these characters was re-lated with fresh fruit bunch yield in the high yield oil palm varieties breeding. Analysis of variance and correlation showed that the average shell thickness had the most coefficient of variation ( CV=88.34%) , average fruit length had the least coefficient of variation (CV=11.99%), fresh fruit bunch yield had extremely significant positive correlation with average fresh fruit bunch weight, number of bunch produced, average fruit weight ( r=0. 882??, 0. 714??, 0.439??), and had significant positive correlation with average fruit length (0.334?). Multiple regression and path analysis showed that practical regression equation x1=-281.511+2.787x4+3.455x5-2.672x6+0.411x7+6.690x8+ 3.664x9 was established by comparing parameters related with multiple linear regression equation. Average fresh fruit bunch weight and number of bunch had maximum direct effects (0.670, 0.439), other characters were relatively less, average fruit weight and average fruit length had maximum indirect effects (0.335, 0.322). The results provide information for the high yield varieties breeding.关键词
