21.04.2021 · Path coefficient analysis has been used by plant breeders to discover traits that are of important interest to breeder so as to select for crop improvement [ 10 ]. Separation of the overall correlations into direct and indirect effects for selecting the best desirable traits for yield improvement can be done through path coefficient analysis.
Path coefficient analysis has been widely used in crop breeding programs to determine the nature of relationships between grain yield and its contributing ...
The concept of path analysis was originally developed by Wright in 1921, but the technique was first used for plant selection by Dewey and Lu in 1959. Path coefficient analysis is simply a standardized partial regression coefficient which splits the correlation coefficient into the measures of direct and indirect effects.

Sep 11, 2020 · Correlation and path analysis were carried out in twenty three tomato genotypes for yie ld characters. The correlation coefficient studies showed that positive association of fruit yield per plant with plant height, number of fruit length, fruit width, average fruit weight, ascorbic acid, total soluble solids and lycopene content.
Path coefficient analysis revealed direct high positive effect on number of grains per ear, 1000 grain weight, flag leaf width and number of effective tillers per plant. View full-text Article
Knowledge of interaction among the characters is very essential in plant breeding to determine the extent and nature of relationship between yield, yield components and physiological characters. Path Coefficient analysis enables a plant breeder to separate direct and the in indirect effects through attributes by partitioning the correlations.
Results of path coefficient analysis of all other traits to grain yield per hectare are given in Table 4 and Figure 1. The results of path coefficient analysis revealed that all the characters studied except plant height, plant count, and number of kernel-rows per ear had positive direct effects on grain yield.
