Determination Of Relationships Between Yield Components İn Bean By Using Path Coefficient Analysis

OpenAlex İngilizce

This study was performed under three location conditions (Kahramanmaras-Center/Turkey, Kahramanmaras-Goksun district/Turkey and Malatya-Darende district/Turkey) in year 2008 with six common beans genotypes (Gungor, Yakutiye-98, Aras-98, Onceler-98, Goynuk-98 and a local genotype). The experiments were carried out in order to determine the relationships between seed yield and yield components. Direct and indirect effects of the yield components on seed yield were found by using Correlation and Path coefficient analysis. It was observed that seed yield was significantly correlated with all traits except plant height and 100-seed weight. On the other hand, the relationship of seed yield per plant with branch number per plant (r=0.78), pod length (r=0.51), seed number per pod (r=0.57), seed weight per pod (r=0.87), pod number per plant (r=0.90), seed number per plant (r=0.88), and seed yield per plant (r=0.92), was positive while correlation of seed yield per plant with first pod height (r=-0.79) was negative. Path analysis depicted that seed number per plant had positive and highest-direct effect (p=2.3274) on the seed yield while seed weight per plant had negative and highest-direct effect (p=-0.9575) on the seed yield.
