Chickpea, Cicer arietinum L., is a staple protein source in many Asian and Middle Eastern countries. Hence, the mineral content of its seed,
especially that of calcium, is of nutritional importance. Calcium is transported through plants and to legume pods almost exclusively via
the xylem stream, with Ca accretion in developing seeds resulting primarily from di.usion of Ca from the adjoining pod wall. Thus, for
seeds of di.ering surface-to-mass ratios, Ca concentration is expected to correlate inversely with seed weight. The relationship between seed
weight and Ca concentration in chickpea seeds was studied using a range of germplasm and derivatives from crosses between types di.er-
ing in seed Ca concentration. Among the cultivars tested, low seed mass was associated with high Ca concentration. However, the study of
hybrid progeny indicated that seed Ca content was mainly determined by genetic factors other than grain weight genes. This ®nding may assist in future breeding of high nutritional quality chickpea cultivars.
