Cull fruit formation (CFF) in cucumber is a serious problem in subtropical regions. A world collection of cucumber was evaluated in the field for tolerance to CFF over 2 years. Tolerance was identified in landraces collected from the centre of origin (India). Highly significant genotypic effects for tolerance to CFF were observed. The data revealed the presence of genetic variability among cucumber inbreds for tolerance to CFF, which would be useful to develop CFF‐tolerant varieties or hybrids. Genotype‐by‐environment interaction for tolerance to CFF was not detected. Twenty‐one F 1 hybrids evaluated for tolerance to CFF indicated the dominance of a low CFF trait which appears to be controlled by many dominant genes. The in breds ‘JL‐1’, ‘JL‐2’ and ‘JL‐11’ would be good choices as parents for developing CFF‐tolerant cucumber hybrids.
