Abstract
The study was conducted at farmers’ field of Itbaria, Patuakhali sadarupazila under Patuakhali district during January to April 2016under the agro ecological zone AEZ-13 (Ganges Tidal Flood plain). This site was located in between 22°14' and 22°29' North latitudes and in between 90°12' and 90°28' East longitudes of Bangladesh. Fifteenmungbean varieties viz., BARI Mung-1, BARI Mung-2, BARI Mung-3, BARI Mung-4, BARI Mung-5, BARI Mung-6, BINA Moog-4, BINA Moog-5, BINA Moog- 6, BINA Moog-7, BINA Moog-8, BU Mug-1, BU Mug-2, BU Mug-4 and Patuakhali local Mung were tested to select best suitable variety for costal region.The experiment was laid out in randomized complete block design (RCBD) with threereplications. Significant variation was observed among the different mungbeanvarities in respect of majority of the observed parameters.BU Mug-1 showed the tallest plant height while the tallest pod length was observed in BARI Mung-5. The highest number of branches per plant was found in BINA Moog-4 whereas the highest number of leaves per plant found for BARI Mung-6. The highest seed yield and yield attributes like number of pods per plant, number of seeds per pod and 1000 seed weight was recorded in BARI Mung-6 followed by BINA Moog-8 while Patuakhali local Mung produced the lowest yield and attributes. Most of the yield contributing factors of BARI Mung-6 wasfavorable for better yield in coastal region of Bangladesh. Hence the mungbean production can be increased by introducingBARI Mung-6 in costal region.

Highlights
The tallest plant was recorded in BU Mug-1 (43.80 cm) followed by BU Mug-4 (41.40 cm), Bangladesh Agricultural Research Institute (BARI) Mung-5 (41.26 cm) and Patuakhali local Mung (41.13 cm)
The shortest plant was recorded in Bangladesh Institute of Nuclear Agriculture (BINA) Moog-4 (31.73 cm) which was followed by BARI Mung-2 (34.80 cm) and BINA Moog-5 (34.93 cm)
The variety BARI Mung-6 (18.33) produced the highest number of pods per plant followed by BARI Mung-2 (16.27) which was statistically similar to BINA Moog-8 (15.80)
Summary
The rice based cropping pattern has been found as an important cropping system in our country, as such condition short duration crop mungbean can be fit as a cash crop between major cropping seasons It is a major pulse crop in Asia. The low productivity can be attributed to lack of suitable genotypes for different cropping situations (Dikshit et al, 2009). It is grown in three seasons in a year in Bangladesh and more than 70% mungbean area is concentrated in the three southern districts viz. Patuakhali, Barisal, and Noakhali within AEZ 13 and 18 and Patuakhali alone occupies about 30% area (Mondolet al., 2013).
