摘要

Two field experiments were carried out in 2007 and 2008, to investigate grain filling rate (GFR), effective grain filling period (EGFP) and resistance indices of three chickpea cultivars (Hashem and Arman from kabuli and Pirooz from desi type) under well watering (I1: 70mm evaporation from class A pan), gradual water deficit (I2 and I3: 70…90…110…130 and 70…100…130mm evaporation, respectively) and water deficit (I4: 130mm evaporation). GFR, EGFP, grain yield (GY) and biological yield (BY) were significantly affected (P<0.05) by irrigation treatments. Cultivars differed significantly for GFR, EGFP and GY. Interactions of year × cultivar for GY and BY were significant. The pattern of seed dry weight accumulation followed similar two-linear models in the three cultivars under four irrigation treatments. C3 (Arman) had the highest GFR and GY among the cultivars, and had significant differences with C1 (Hashem) and C2 (Pirooz). BY was not different among cultivars. EGFP of C2 (desi type) was significantly less than those of kabuli type cultivars. GY had significant positive correlation with GFR and EGFP. It is concluded that GFR and EGFP can be reliable criteria for selecting high yielding chickpea cultivars under water deficit conditions. Arman had the highest YP, YS, STI, MP and GMP, therefore this cultivar had higher grain yield under both water deficit and well watered conditions.
