The pattern of dry matter accumulation in soybean pod and its relationship with pod shattering was studied using ten soybean genotypes that differed in the extent of pod shattering during three different seasons (kharif 98, Rabi/summer 99 and Kharif 99). Dry matter accumulation in pod and seed increased continuously up to physiological maturity, whereas dry matter of pod shell increased up to 40 days after anthesis and reduced afterwards. Dry matter accumulation in pod and seeds was negatively correlated with pod shattering. The partitioning efficiency of dry matter from pod shell to seed was higher in the pod shattering resistant varieties than the pod shattering susceptible varieties.
