Abstract: Variation and transgressive segregations were studied in the backcross generations of populations involving three crosses in long bean [Vigna sesquipedalis (L.) Fruw]. Trends were different for different crosses. In Cross 1, high mean, variance and significant transgressive segregation (STS) pattern were exhibited by BC2F1 generation for shelf life, pod yield per plant and pod weight. In Cross 2, high means were shown by BC1F1 generations for shelf life and pod yield per plant, but high STS were observed in BC2F1 generation for shelf life, BC1F1 for pod yield per plant and BC1F2 for pod weight. In Cross 3, BC1F2 generation revealed high variances for shelf life, pod yield per plant and number of pods per plant, but highest STS values were revealed for BC1F3 (selected) for shelf life and pod yield per plant, BC2F1 for number of pods per plant, and BC1F2 for pod weight. In general, shelf life was found to have exhibited high mean and STS in the BC2F1 generation. Pod length, in general did not show good transgressive segregation in the crosses. Exploitation of these transgressive segregants in breeding programmes for improvement of the character of interest is suggested.
