Abstract

The effect of flowering pattern and floral abscission on the yield and yield attributed characters of French bean varieties were studied in a field of Bangladesh Agricultural Research Institute, Gazipur. There nine varieties were treated- (1) BARI Jharsheem-1 (2) BARI Jharsheem-2 (3) Sylhet local-1 (4) Sylhet local-2 (5) Sylhet local-3 (6) Sylhet local-4 (7) Sylhet local-5 (8) Sylhet local-6 and (9) Sylhet local-7. Among the treatments, the highest number of flower was recorded within 5 to 8 days in BARI Jharsheem-2 although, the maximum flower opened within 5 to 8 days and following ceased within 15 to 20 days after first flowering. The total number of flowers per plant varied between 19.36 to 45.06 and 22.0 to 47.20 in two consecutive years while percentage of pod abscission varied between 70.53 to 82.26 and 73.46 to 80.75 in two consecutive years. The maximum yield of French bean was obtained from BARI Jharsheem-1, however identical yield was obtained from BARI Jharsheem-2 treatment. The flowering pattern and percent abscission as well greater number of pod were found to be the influential character for the highest yield of French bean. In addition, seed yield was strongly correlated to the number of opened flowers as well as number of mature pods.
