Using Path Coefficient Analysis to Determine the Relationship between Yield and Yield Components of Dry Bean (Phaseolus vulgaris L.)

Abstract

This study was conducted to determine relationship between yield and yield components of 10 dry bean varieties for 2 years. Field trials were carried out under Tokat-Turkey ecological conditions and utilized a randomized complete
blocks design with 3 replications. The relationship between total seed yield and plant height, number of pod per plant, number of seed per pod, number of seed per plant, seed yield per plant, 1000 seed weight, and total biological yield were investigated. Significant and positive relationship were found between total seed yield and number of pod per plant (0.594**), seed yield per plant (0.527*), total biological yield (0.877**), number of seed per pod (0.455*), number of seed per plant (0.420*). Negative and non-significant relationships were determined between total seed yield and plant
height (-0.234). There was positive but no significant relationship between total seed yield and 1000 seed weight (0.245). According to path analysis results, the most important characteristics determining seed yield in dry bean were total
biological yield and number of seed per pod.
