An experiment was conducted during summer season of 2006, 2007 and 2008 to study the stability parameters viz., regression coefficient (bi) and mean square deviations (S2di) from linear regression, along with per se performance of 12 varieties of bush type French bean for 9 yield related characters. Highly significant pooled deviation for days to 50% flowering, plant height, pod length, pod width and pod girth and significant/highly significant GxE (linear) interaction for number of pods/plant and pod weight indicated the preponderance of non-linear components of GxE interaction. The stringless and round podded line HAFB-2 was high yielding, stable and showed average response to change in environmental condition for green pod yield (14.42 t/ha) and can be recommended for summer season cultivation in Chotanagpur plateau region of Jharkhand. The line was also better performing, stable and suitable for favourable environment for pod weight (6.98 g) and pod girth (0.93 cm) and suitable for unfavourable environment for number of pods/plant (13.85). The line HAFB-4 was also better performing, stable and suitable for favourable environment for green pod yield (13.85 t/ha), number of pods/plant (14.94) and pod girth (0.92 cm). The stringless and flat podded variety Swarna Priya was also better performing, stable and suitable for favourable environments for green pod yield (13.86 t/ha) and plant height (45.46 cm). The variety Arka Komal was better performing, stable and suitable for favourable environment for pod weight (7.19 g), pod length (14.90 cm) and pod width (1.06 cm) and suitable for unfavourable environment for early flowering (37.88 days).
