Description Chickpea is one of the most cultivated grain legumes in Ethiopia for grain production and amelioration of soil fertility through N-fixation, and income generation. This study was conducted to estimate the heritability and correlation analysis of N-fixation in chickpea. Six F1 crosses were evaluated in lath house during the year 2014/15 using randomized complete block design (RCBD) with two replications at Debre Zeit Research Center. Heritability of the characters was estimated in F1 generations from the combining ability analysis of a di-allele cross using fixed model expectations of mean squares for GCA and SCA . The calculated narrow sense heritability was high (>0.50) for all traits except for seed filling duration, number of pod per plant, shoot nitrogen fixation, grain harvesting index and grain production efficiency. All symbiotic traits such as number of nodules, shoot nitrogen fixation, N fixed in biomass, N fixed in grain, Nitrogen harvest index (NHI), Grain N yield, Shoot N yield, Biomass N yield, Nodule dry weight, Shoot and grain protein contents and Nitrogen showed strong positive association with yield and other agronomic traits, indicating the improvement of symbiotic traits results in the improvement of other agronomic traits of the crop. The prevailing high heritability indicates the possibility of improving the traits either by selection or crossing of selected parents. This study is first of its kind in Ethiopia, and helps the future breeding and genetics in chickpea dealing with the nitrogen fixation processes.
