Abstract

In order to determine the correlation between some traits and YIELD components in three chickpea cultivars as well as cause and effect relationships between them, The experimental plots once crushed (Split plot) the base of a randomized complete block design with four replications in the Shirvan Chardavel region of Ilam,1387-1388 was conducted during the crop year. The main factor of four irrigation treatments, irrigation control, irrigated once in 50% of budding, Irrigation at 50% flowering, and Irrigation filling pods, and sub-factor 3 genotype. Analysis of variance based on the effect of irrigation treatments on grain YIELD, biological YIELD, harvest index, The number of fertile pods per plant, seed number per plant and seed weight was significant at the one percent level. Generally performed in a water pod filling stage and the flowering of the 41.3 and 29.3 percent YIELD was higher than control. Observations showed that the highest YIELD significant positive correlation with other traits of biological function and harvest index belonged Grain YIELD and protein YIELD had a negative correlation. To remove the effects of ineffective or low impact on YIELD traits in the regression model, STEPWISE REGRESSION was used. Important traits in grain YIELD in this study, harvest index, seed weight and seed number per plant, respectively The model has a coefficient of determination (0.999), respectively. PATH ANALYSIS results showed, harvest index and the highest positive direct effect on grain YIELD had and the seed weight and number of seeds per plant and a negative indirect effect on performance can be applied.
