Summary:Genotype-location interaction was studied for grain yield, protein content and maturity period for 15 were exotic and locally collected varieties/lines of proso millet across three different locations of Bangladesh. Varieties/lines differed significantly for genotype-location (G-L) interactions for all the characters studied. BPm-34, BPm-48 and BPm-27 were found to be the most stable varieties while BPm -27, BPm-103 and BPm-146 were stable for protein content and most of the varieties/lines except BPm-37, BPm-48 and Bagaikandi were stable for maturity period over all locations. Only BPm-159 and BPm-37 had the above average stability for grain yield, thus suitable for poor environment. No other varieties/lines were considered suitable for either favourable or poor environment in respect of any characters. The study suggests that BPm-27 could be used in breeding programs to increase stability for grain yield, protein content and maturity; BPm-34 for grain yield and maturity and rest of the stable varieties/lines be used independently to impart homeostasis to individual characters.
