evaluation of accessions and varieties of chickpea (cicer arietinum l.) based on agro-physiological traits

in order to study of genetic variation and identification of yield components in chickpea, a trial consists of 96 accessions of chickpea received from iranian gen bank (seed and plant improvement institute) along with five checks (arman, bivanij, jam, hashem and ilc-482) was conducted based on an augmented design in 2005-06 cropping season at research farm of agricultural college, razi university, kermanshah, iran. for evaluating of accessionst the morphological, physiological and phonological traits during plant growth were measured. the result of anova and mean comparisons showed significant differences among accessions for some of the traits i.e., days to first flower opening (df-1), days to 50% flower opening (df-50%), days to first pod opening (dp-1), days to 50% pod opening (dp-50%), days to maturity (dm), days to 90% maturity (dm90%), plant height (ph), height of first pod (ph-1p), number of pod per plant (nppp), number of single seed per pod (1sp), number of double seed per pod (2 sp), and pod width (wp), number of see per pod (nspp) and 100 seed weight (100sw), correlation coefficient analysis showedthe grain yield significantly correlated with biomass (r=0.84**), 1sp (r=0.80**) and harvest index (hi, r=0.44**). stepwise regression analysis showed that the nppp, number of seed per pod (nspp), 100sw, biomass, hi, canopy width (canw) and dp-1 positively affected on grain yield, while ph-1p and df-1 negatively affected on grain yield.
