Genetic and Cultural Control of Fusarium Root Rot in Bush Snap Beans

Abstract

(...) Deep subsoiling was more effective than narrow row spacing in increasing seed yields. Irrigation at 50% vs. 60% available soil moisture did not reduce seed yields. Because of its high genetic resistance to Fusarium root rot, bean line FR-266 had a seed yield almost double that of susceptible cultivar Blue Mountain under most combinations of cultural practice treatments. Growing resistant FR-266 combined with subsoiling, narrow rows, and irrigation after 50% available soil moisture depletion raised 3-yr mean seed yields to 2836 kg/ha, which was 310% of the yield for susceptible Blue Mountain grown under standard cultural practice conditions
