An investigation of determination for correlation and path analysis of yield and yield component in peanut (Arachis hypogaea L.)

In this research, of which field experiments were layout as to NC-7 peanutvariety in Çukurova Region, positive correlation between fruit yield and weight of100 seed (0.871), weight of 100 fruit (0.789), fruit yield per plant (0.696), internalratio (0.858), weight of second quality fruit (0.700) and ratio of oil (0.842) wasconcluded, while there exists negative correlation between fruit yield and number offruit per plant.As a result of Path Analysis, the yield characteristics which directly affect theyield and are the highest can be listed as weight of 100 fruit (0.8346), fruit yield perplant (0.4537), internal ratio (0.2987), weight of 100 seeds (0.1902) and ratio of oil(0.1171). Consequently, it is concluded that in improvement facilities, weight of 100fruit and fruit yield per plant can be utilized as main criterion.Key words: NC-7, Peanut, variety, Path , Correlation
