Abstract

In order to study CHICKPEA rhizobia BIODIVERSITY in Khorasan province as one of the major origins of CHICKPEA, root nodules were collected from different parts of the province and a total 36 stain were isolated and purified. 24 isolates were confirmed after infection test, using Leonard jar system and tested with uninoculated and N controls (complete nutrient solution) for nitrogen percent and content, root and shoot dry weight, symbiotic effectiveness and the number and weight of nodules in aseptic N-free hydroponic sand culture system. Results indicated significant differences (p< 0.01) among isolates for all parameters studied. Root nitrogen content was lower than shoot in all isolates indicating transfer of nitrogen from root to shoot immediately after biological fixation. Regression coefficient for nodule numbers with shoot nitrogen content was low. Finally five superior isolates were selected in terms of shoot nitrogen content and symbiotic effectiveness. In the last trial, symbiotic effectiveness in four CHICKPEA cultivars (two Kaboli and two Desi type) were evaluated by inoculating with selected isolates under soil conditions. In general, all isolates increased nodules in inoculated plants, although these differences were statistically significant only for few isolates. Nodule numbers in Kabuli cultivars were significantly higher than Desi cultivars. Dry weight of inoculated plants were higher from 2.5 percent in introduced isolate CP36 to 19.3 percent in isolate no. 27 as companed, Compared with control (80 kg N/ha). Simbiotic effectiveness in Flip CHICKPEA cultivar was 31.8 percent higher than N control and this was the highest between- CHICKPEA cultivars. This study indicated that inoculation of CHICKPEA cultivars with local isolates, increased shoot and plant dry weight, nodulation and symbiotic effectiveness.
