Correlation and relationships between seed yield and other characteristics in chickpea (Cicer arietinum l.) cultivars under deterioration

Abstract

This study was done in order to evaluate the relationships between grain yield and the other characteristics with two cultivars of chickpea (Hashem and Arman) in deterioration (0 (control), 7 and 14 days). The experiment was a factorial completely randomized design with 2 factors. It was conducted on a research farm at Gonbadekavoos High Education Center- Iran in 2009. At harvest time, height of the plants, filled and unfilled pods per plant, number of seeds per plant, plant dry weight and yield were measured. Results showed the yield had highly positive correlation with filled pod per plant (r = 0.96)) (p<0.01).  In Arman and Hashem cultivar, yield had highly correlation with seed number per plant (r = 0.95) (p<0.01) Dependence of seed yield to height was great with deterioration 14 days; and the correlation coefficient between filled pod number and height after 7 days deterioration was significantly (P<0.01) negative (r = -0.95) (P<0.01) but it was of greater magnitude in 14 days deterioration (r = 0.79) (P<0.01).   Key words: Chickpea, correlation, deterioration, relationship, yield.
