During the period 2004 – 2006 was performed a study with 21 garden pea genotypes for determination of the relationships between qualitative characters in garden pea by Paht-analysis. It was established that the highest direct effect on plant productivity have the characters internode length 16.7 and grain number per pod 16.0. Their indirect effect is positive and high as well as by the pod number and grains per plant and by the plant height and unproductive nodes number. It is interesting to be underlined that the high correlation of the plant productivity with grains per plant r = 0.76, height to first pod r = 0.69 and pod length r = 0.67 was determined on their indirect effect through the pod number, unproductive nodes number and the internode length while in the grain number in pod – mainly by the direct effect.
