Abstract

Naturally occurring plants with large differences in nodulation capacities (including nonnodulation) within chickpea cultivars have been reported. Two cultivars, ICC 4948 (= G 130) and ICC 5003 (= K 850), from which such nodulation variants were identified during the mid-1980s, were susceptible to fusarium wilt a widely occurring soilborne disease, caused by Fusarium oxysporum f. sp. ciceri. This made multilocational evaluation of the nodulation variants difficult in some important chickpea- growing areas. Studies reported here suggest that high-nodulating variants can be identified from advanced breeding chickpea lines that were reported as tolerant to fusarium wilt. The potential value of these and previously reported nodulation variants for quantification of N2 fixation, additional residual effect owing to additional N2-fixation by the high nodulating selections, improving soil health, and better understanding of the symbiotic process have been discussed. The potential to develop stress- tolerant symbiotic chickpea lines has been indicated through successful identification of high mineral-N tolerant symbiotic selections.
