Fifteen genotypes/varieties of french bean (Phaseolus vulgaris L.) were evaluated during 2004–2007 for stability of green pod yield. Pooled analysis of variance revealed significant differences amongst genotypes and substantial genotype x environment interaction effect on green pod yield. The results revealed that the genotypes viz., IIHR-909, DPFBBS-1, HAFB-1, Contender, HAFB-2 and MFB-3 possessed specific adaptability for better/rich/favourable environments and could be cultivated under rich environments created through better/well management practices with respect to fertilizer application, irrigation, weed control etc. In addition to these, genotypes IVFB-1 and IVFB-2 were highly stable and expected to perform in a stable manner over the fluctuating environmental conditions. So, these genotypes might play a significant role as promising parents in the future breeding programmes of bush type French bean or as such can be recommended for the cultivation under north-western Himalayan region.
