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).
